Bombs in Baghdad, 1950–1951: Israeli Discourse and History
Authors: Meir-Glitzenstein Esther
Published: July 2024

The massive migration of Jews from Islamic countries, and in particular the fact that most of them came to Israel, led to the formation of various narratives that served the interests of the different groups involved. Particularly notable is the clash of narratives in the case of Iraqi Jews who were brought to Israel over a short period of time. In contrast to the Israeli-Zionist narrative, which explained the immigration as the result of both a national-religious yearning and persecution, Iraqi Jews presented a counter-narrative in which the State of Israel, through acts of terror, panic, and propaganda, pushed or even forced them to leave Iraq. The debate over these narratives also involves the story of two Iraqi Jews, Yosef Basri, and Shalom Saleh, who were executed in Iraq for allegedly planting bombs during that period. The article examines these narratives through their story, while attempting to compare the narratives to the findings of historical research and thus shed light on the place of historical events in current political and ideological struggles.
A Pragmatic Analysis of Conversational Implicatures in English Drama and their Role in Teaching Critical Literacy

Published: July 2024

This study aims to explore the role of conversational implicatures in English drama in developing students’ critical literacy. It identified conversational implicatures conveyed by characters of the selected drama texts, provided possible interpretations of the implicatures basing on Grice’s Cooperative Principle maxims, and critically analyzed the role of conversational implicatures in English drama in developing students’ critical literacy. The data were collected from the implicatures conveyed by the characters of two selected drama texts. These are ‘Family Abuse’ by Bernard Mersier and ‘The Edge’ by Paul Symonloe. Grice’s pragmatic theory of Cooperative Principle and its maxims were used to identify and interpret conversational implicatures in the selected drama texts. Forty-two (42) conversational implicatures were identified from these texts. These implicatures were categorized into types basing on the four conversational maxims, and each conversational implicature was taken as data. Using Grice’s interpretive model and the social context of the drama, what the characters implied by their utterances were explained together with the reasons for the implicatures. The Luke and Freebody’s four resources model of critical literacy was then used to study the role of conversational implicatures in English drama in developing students’ critical literacy. The study concluded that conversational implicatures in English drama develop students’ critical literacy by enabling them to study a drama text from a social angle and evaluate the social aspects that may have influenced the meaning of the characters ‘utterances. Therefore, it was suggested that drama texts should be used in language teaching and learning as they ease the teaching of conversational implicatures which can foster the development of students’ critical literacy.

A fenda facial sempre intrigou a sociedade por ser uma malformação que estigmatiza seus portadores. Os poucos dados relacionados à observação ultrassonográfica pré-natal dessa malformação, no Brasil, incentivaram o seu estudo no Setor de Medicina Fetal do departamento de ginecologia e obstetrícia do hospital das clínicas da faculdade de medicina da universidade de São Paulo (DOG, HCFMUSP). Métodos e objetivos: O estudo foi desenvolvido de maneira descritiva, sendo selecionados 97 fetos portadores de fenda facial diagnosticada ao ultrassom morfológico no Setor de Medicina Fetal da Clínica Obstétrica do DOG da HCFMUSP, sendo divididos em três grupos específicos: grupo I (fenda facial isolada), grupo II (fetos com fenda facial e outras malformações associadas) e grupo III (fenda facial cursando com aneuploidia) com o objetivo de estudar as características destes grupos separadamente e em conjunto. Resultados: Houve confirmação do diagnóstico ultrassonográfico no pós-natal do tipo de fenda facial em 88,7%; idade materna no diagnóstico de 27,8 ± 7,8 anos; idade gestacional no diagnóstico de 27,4 ± 5,9 semanas; fraca relação com história familiar; prevalência da fenda lábio palatina; prevalência da fenda labial esquerda na fenda facial isolada (grupo I) e da fenda lábio palatina mediana na fenda facial associada a outras malformações (grupo II) e também na fenda facial associada à aneuploidia (grupo III); a fenda labial e a fenda lábio palatina foram prevalentes no sexo masculino e a fenda palatina isolada no sexo feminino; maior associação com malformações musculoesqueléticas, cardíacas e holoprosencefalia; prevalência da associação com trissomia do 13; idade gestacional média no parto de 33,5 ± 6,3 semanas, sendo de 38,8 ± 1,17 semanas no grupo de fenda facial isolada (grupo I); peso fetal médio ao nascimento de 2,105 g ± 1086g, sendo de 3,027 ± 1910g no grupo de fenda facial isolada (grupo I); mortalidade na presença da fenda facial de 71,7 % com índice de mortalidade de 95,4 % na fenda facial associada a outras malformações (grupo II) e  índice de mortalidade de 100% na fenda facial associada a aneuploidia ( grupo III), sendo que não houve óbito no grupo da fenda facial isolada (grupo I). Conclusão: Houve uma excelente correlação entre o tipo de fenda facial diagnosticada pela ultrassonografia no período gestacional e o tipo de fenda facial observado no pós-natal, sendo a avaliação do palato foi o maior problema técnico para o diagnóstico da fenda facial. A idade gestacional no diagnóstico da fenda facial foi tardia e fetos com fenda facial isolada apresentaram bom prognóstico, com idade gestacional no nascimento e peso compatível com o termo. Fetos com outras malformações, independente de presença de aneuploidia, apresentaram mal prognóstico, com altíssima letalidade e tendência à prematuridade e baixo peso.

Authors: Melo Thainan Jardim de , Pimenta Yasmin Dantas , Portella Claudio Elidio Almeida
Published: July 2024

O Manguito Rotador (MR), composto pelos músculos supraespinhal, infraespinhal, redondo menor e subescapular, é crucial para a estabilidade do ombro. Lesões no manguito rotador, especialmente no tendão supraespinhal localizado entre o acrômio e a cabeça do úmero, são comuns devido à hipovascularização na “zona crítica”. Essas lesões podem ser parciais ou totais e apresentam sinais clínicos como dor intensa, inflamação, diminuição da funcionalidade, movimentos antálgicos, redução da amplitude de movimento (ADM), bloqueio articular e contratura muscular. A fisioterapia é fundamental para melhorar esses sintomas e restaurar a funcionalidade. Materias e métodos: Trata-se de um estudo de caso que teve por objetivo analisar a atuação da Fisioterapia nos pacientes com lesão de Manguito Rotador. As intervenções utilizadas foram alongamento terapêutico, cinesioterapia artrocinematica, eletrotermoterapia, manipulações articulares, cinesioterapia ativa, cinesioterapia ativa assistida e cinesioterapia resistida. Resultados: Os resultados deste estudo foram obtidos através da avaliação e reavaliações da paciente no período de 7 meses, onde constatou-se e comparou-se os ganhos através da atuação terapêutica. Conclusão: No presente estudo, observamos que a fisioterapia trouxe uma melhora significativa no quadro clínico da paciente, melhorando a qualidade de suas AVD’s, mas não foi suficiente para alta fisioterapêutica devido às limitações remanescentes. Para lesões mais graves, a literatura indica que a intervenção cirúrgica pode ser necessária para recuperação total. Concluímos que a fisioterapia é indispensável no tratamento de lesões do manguito rotador, pois proporciona melhorias significativas na dor e na funcionalidade.

Abstract. Black carbon (BC) is one of the most important climate forcers with severe health effects. Large uncertainties in radiative forcing estimation and health impact assessment arise from the fact that there is no standardized method to measure BC mass concentration. This study presents a 2-year comparison of three state-of-the-art BC measurement techniques at the high-altitude research station Pic du Midi (PDM) located in the French Pyrenees at an altitude of 2877 m above sea level. A recently upgraded Aethalometer AE33, a thermal-optical analyser Sunset and a single-particle soot photometer SP2 were deployed to measure simultaneously the mass concentration of equivalent black carbon (MeBC), elemental carbon (MEC) and refractory black carbon (MrBC), respectively. Significant deviations in the response of the instruments were observed. All techniques responded to seasonal variations in the atmospheric changes in BC levels and exhibited good correlation during the whole study period. This indicates that the different instruments quantified the same particle type despite the fact that they are based on different physical principles. However the slopes and correlation coefficients varied between instrument pairs. The largest biases were observed for the AE33 with MeBC values that were around 2 times greater than MrBC and MEC values. The principal reasons of such large discrepancy were explained by the mass absorption cross section (MAC) that was too low and C values recommended by the AE33 manufacturer and applied to the absorption coefficients measured by the AE33. In addition, the long-range transport of dust particles at PDM in spring caused significant increases in the bias between AE33 and SP2 by up to a factor 8. The Sunset MEC measurements agreed within around 17 % with the SP2 MrBC values. The largest overestimations of MEC were observed when the total carbon concentrations were below 25 µg C cm−2, which is probably linked to the incorrect determination of the organic carbon (OC)–EC split point. Another cause of the discrepancy between instruments was found to be the limited detection range of the SP2, which did not allow for the total detection of fine rBC particles. The procedure used to estimate the missing mass fraction of rBC not covered by the measurement range of the SP2 was found to be critical. We found that a time-dependent correction based on fitting the observed rBC size distribution with a multimodal lognormal distribution is needed to accurately estimate MrBC over a larger size range.

The first NASA spacecraft to visit and explore planet Venus since the 1990s will be the Venus Emissivity, Radio science, InSAR, Topography, And Spectroscopy mission (VERITAS) orbiter. The Venus Emissivity Mapper (VEM) onboard the spacecraft is designed for surface mapping of Venus within dedicated atmospheric spectral windows. The instrument will provide global coverage for the detection of thermal emissions like volcanic activity, surface rock composition, water abundance, cloud formation and their dynamics by observing 14 narrow filter bands in the near-infrared to short-wave infrared (NIR, SWIR) range of 790 nm to 1510 nm. An almost identical instrument will be part of ESA’s recently announced EnVision mission to Venus, the VenSpec-M in the Venus Spectroscopy Suite (VenSpec). The utilized photodetector for both missions will be an InGaAs type imaging sensor with integrated thermoelectric (TE) cooling, comprising a 640x512 pixel array with 20 µm pixel pitch.In general, a space environmental qualification of electronic devices combines its susceptibility to radiation induced single event effects (SEE) and the evaluation of permanent degradation effects due to total ionizing dose (TID) and displacement damage dose (DDD) and the assessment of the radiation-induced noise.After the qualification test with heavy-ions focusing on SEE performed at Radiation Effects Facility in Finland (RADEF) was completed, our imaging sensor was subject to a proton irradiation test campaign at Helmholtz-Zentrum Berlin (HZB) for combined TID and DDD testing, for the assessment of the radiation-induced noise and to investigate proton-induced SEE. 
On using polarization filters to build a high performance polarimeter/spectrometer
Authors: Erwin Justin , Vanhellemont Filip , Willame Yannick , Robert Séverine
Published: July 2024

Polarization is a topic largely neglected in spectroscopic investigation of planetary science. While true the degree of polarization is small in many observational situations, one can show that it has incur some bias in recent retrieval studies. Looking towards the future, with more high-performance spectrometers being sent to other planets, we would argue that future spectrometers should consider addressing polarization early in their design.Polarization of light commonly occurs dues to scattering by surfaces, aerosols (e.g. clouds), and molecules. The different polarization states of light entering the spectrometer instrument can have different transmission efficiencies to arrive at the detector, leading to a polarization sensitivity of the instrument. The combination of these two mechanisms leads to an incorrect calibration of radiances used for science retrievals. Especially when the target absorption features and the polarization features are correlated/anticorrelated, this leads to an unknown error in the retrieval. One can adapt their end-to-end tool to characterize this error and include it in the total error budget.One can include other elements in their design to correct for, or measure, the polarization. The simplest method might be to include a polarization scrambler early in the optical path. This would nullify the polarization sensitivity of the instrument. Then the retrieval tool can ignore polarization in the forward model completely. Still, in some cases, the forward model including or not including polarization can lead to large difference in the total radiance entering the instrument due to missing terms in scattering. Therefore, including a scrambler can still lead to some retrieval error. We present some estimations of this bias from recent Mars missions.Alternatively, one can use a combination of polarized filters and perform simultaneous (or near simultaneous) observations of the reflected radiance. By combining these spectra and using the knowledge of (and some assumptions based on) the observation geometry, one can determine the total radiance and some elements of the polarization state. We will present different options for filter combinations and discuss their calibration accuracy and performance. We present some design options for a spectrometer going to Venus, with the trade offs that need to be considered. As a bonus, the polarization state is a result of properties of the scattering medium. So, for instance, it can be used to constrain the aerosol size and composition.
Temperature Structure, Chemistry, and Clouds in the Atmosphere of Neptune Revealed by JWST

Published: July 2024

We present observations and analysis of Neptune’s atmosphere from JWST, providing new constraints on hydrocarbon abundances, cloud properties, and temperature structure across the planet’s disk.  Spatially-resolved spectra from JWST NIRSpec (1.6–5.2 µm) and MIRI (4.9–28.5 µm) were acquired in June 2023 and amount to the most comprehensive infrared observations Neptune’s atmosphere since Voyager 2.  We compare these observations and results to similar observations of Uranus made six months prior.From the ground, spatially resolved observations of Neptune’s mid-infrared emission are limited to imaging targeting the brighter regions of the infrared spectrum (i.e. 8-µm emission from stratospheric methane, 12-µm emission from stratospheric ethane, and 17-25 µm thermal emission from the hydrogen continuum). From space, Voyager provided infrared spectroscopy of Neptune at close proximity in 1989 (after similarly observing Uranus 3 years earlier), but lacked the sensitivity needed to adequately measure mid-infrared emission from stratospheric hydrocarbons.  Between 2004 and 2006, the Spitzer Space Telescope observed both planets' mid-infrared spectra between 7 and 36 µm, but Spitzer lacked the spatial resolution necessary to resolve potential thermal and chemical structure across the disk.Now, with its exceptional sensitivity and outstanding spatial and spectral resolution, JWST reveals Neptune's stratospheric temperature and chemistry with exquisite new detail, placing new constraints on hydrocarbon abundances, cloud properties, and temperature structure across the disk. In this talk, we introduce these new data along with results of an initial radiative transfer analysis.  We briefly compare and contrast these finding with those of our recent similar analysis of Uranus.With a projected lifetime of over a decade, JWST promises to continue providing exciting new insights into the atmospheric structure, composition, and variability of the ice giants for years to come.

Published: July 2024

Artemis 3, scheduled for no earlier than September 2026, will mark the return of humans to the Moon. This mission will include four astronauts, featuring the first woman and the first person of color to land on the lunar surface. Simulating space missions by replicating real-life conditions is crucial for understanding human behavior. As part of this effort, the EuroMoonMarsPoland initiative, established through a collaboration between the AATC Analog Astronaut Training Center and the ILEWG Lunex EuroMoonMars, is conducting several seven-day missions. In May 2024, a crew “4Artemis3” consisting of Clara Laforet from France and Matthew Harvey from Ireland will be isolated in a Moonbase analogue to reflect the composition of the Artemis 3 team. They will undertake various individual and collective scientific experiments to analyze the effects of the space environment. These activities aim to measure specifically the psychological impact of isolation, identifying optimal strategies to maintain astronauts' mental health and performance. The use of virtual reality equipment and exercises as alternatives to traditional exercise gear in isolated settings will be scrutinized. Additionally, experiments involving robots, such as rovers, will investigate the dynamics of astronaut-robot interactions, assessing how effectively astronauts can manage and collaborate with these robots to perform tasks on the lunar surface. The surface crew activity will be also supported by AATC mission control center crew that will therefore simulate the Artemis 3 two astronauts staying in LRHO Lunar Retrograde Halo Orbit and mission support from Earth (safety, operations, technologies, science, public outreach). The results of this campaign will enhance our scientific understanding of human behavior in space and will be showcased during the presentation.
Geodynamica: slinging Earth and (exo)planets’ structure and dynamics into Diamond Open Access

Published: July 2024

The past decade has seen the consolidation of open access practices in scientific publishing, with funding bodies, international agencies and academic institutions requiring free access to not only scientific papers but also other output such as datasets and computer codes. While mostly embraced by the scientific community, the transition to open access practices has led multiple academic publishers to offer Gold Open Access schemes, under which scientific papers are free-to-read. Compared to the traditional publication models, Gold Open Access comes at a much higher cost for the authors, normally of thousands of US Dollars for a single paper. These practices have had a documented negative impact on the scientific publishing landscape, from the rise of predatory journals to the broadening of the economic divide between academic institutions.Partly in response to the negative impact of Gold Open Access practices, different fields of Earth Sciences have recently seen the rise of several community-led, Diamond Open Access journals (e.g., Volcanica, Tektonika, Seismica). These journals are free-to-publish and free-to-read. The aim is to remove financial barriers to scientific publishing by publishing peer-reviewed articles at no cost to both authors and readers, thus offering a platform for true open science. Diamond Open Access journals are created and maintained by the very same scientific community they aim to serve, thus removing economical and business considerations that drive a large fraction of the modern publishing landscape. Therefore, community-led journals offer a high-quality alternative to classical for-profit scientific journals.We are pleased to announce a new Diamond Open Access journal initiative called Geodynamica, with the aim of promoting free-to-publish and free-to-read research on the  dynamics of the Earth’s and (exo)planets’ interior. Geodynamica was born in 2023 thanks to the effort of six scientists, who form the core committee that coordinate the efforts of the various teams. The target launch date for the journal is autumn 2024. Geodynamica aims at promoting academic discourse and disseminating research pertaining to the quantitative study of Earth and (exo-)planetary internal structure, dynamics, and evolution from observational to modelling perspectives.Geodynamica enjoys the support of eScholarship (University of California), and hugely benefits from the experience of existing community-led journals within the geosciences community, namely Volcanica, Tektonika and Seismica.In this contribution, we will provide the vision behind this initiative, report on the structure of this journal, its scope, and the remarkable community effort that will make this new diamond open access journal a reality.

Published: July 2024

The diversity of upcoming exoplanetary missions, both space and ground-based, will provide unprecedented view of the extrasolar planet population in the broader Galactic context. Missions like PLATO and ARIEL will build on the work of Kepler and TESS by discovering more planets with bright host stars and characterising the atmospheric compostition of a miriad of planetary systems. This is already presenting a need for systematic and coordinated ground-based follow-up observations to better support these missions. The rapid reaction and flexible, remote scheduling capabilities of robotic facilites makes them powerful tools for scientific explotation of time domain topics in general, and in particular of exoplanets and characterisation of their host stars.We introduce the Joan Oró telescope (TJO), a fully-robotic 0.8m telescope at the Montsec Observatory dedicated to astrophysical research and Space Surveillance and Tracking activities. We present past and ongoing involment in exoplanetary research, such as photometric follow-up programs of CARMENES, TESS and ARIEL targets, and the potential for transient alert observations and unattended long-term monitoring in support of the next generation of exoplanetary surveys.
5 years of Jupiter impacts monitoring and observations

Published: July 2024

After 1994 Shoemaker/Levy 9 comet fragmentation and impacts on Jupiter was predicted and observed by professional astronomers, it was estimated that impacts on Jupiter should be very rarely observed events, maybe once per century. But an Australian amateur observed dark traces of an impact on Jupiter with his backyard telescope in 2009 and observed a flash provoked by another smaller impactor on Jupiter atmosphere in 2010 [1]. This started a series of 13 observations of such events [2],[3], and a long monitoring program supported by a software (DeTeCt) aiming at estimating such impacts frequency, through both semi-automatic detection of flashes on amateur videos of Jupiter and logging of all observations period without any events.With those 13 observations, we have now enough data to analyze the apparent distribution of those impacts’ location on Jupiter. 75% occurred in the equatorial area (between -30° and 30 ° latitude), which could be an indication that the impactor bodies are originating from the same orbiting plan as Jupiter.Over the years, we could collect a year worth of videos analysis with our software, from 262 different observers (almost 360 000 videos). To refine the rate of Jupiter impacts’ frequency estimation, we analyzed the data in a more detailed way than before, per Jupiter apparition, and considering for each apparition the number of impacts discovered, the total duration and period of all negative observations collected through DeTeCt. Focusing on most relevant apparitions with around or more than a month worth of data collected, we find an impact frequency varying from none per year (no impacts detected in 2018 and 2022), and ~80/year (4 observed in 2023). Averaging the result for these apparitions (between 2018 and 2023), we estimate the impact frequency to ~29/y (twice as much as the previous way of estimating it). References:[1] Impact flux on Jupiter: From superbolides to large-scale collisions ", Hueso R., Delcroix M. et al., Astronomy & Astrophysics, September 2013[2] Small impacts on the Giant planet Jupiter, Hueso R., M.

Asteroid Thermal Inertia Analyzer

Published: July 2024

We developed the new model and corresponding publicly available software for determining the surface thermal inertia (TI) of asteroids [1,2]. We named it ASTERIA (Asteroid Thermal Inertia Analyzer). The model allows TI estimation based mostly on population-modeled input parameters in its basic variant. However, as in general cases the model may not work well if all physical parameters are population-based, we identified the set of critical parameters, which includes the diameter, albedo, and rotation periods of an object.ASTERIA has been validated using data from Bennu and ten other well-characterized NEAs. The results agree well with the literature values, demonstrating the model's reliability for TI analysis.We have identified a set of 38 near-Earth asteroids (NEAs) for which all the input parameters critical for the ASTERIA model to work reliably are available and presented the new TI for those objects. Among these 38 NEAs, 29 are classified as PHAs. It makes our results highly relevant from the planetary defense point of view. Our sample of new TI estimates also includes 31 sub-kilometer-sized asteroids. At the same time, there are only 17 other literature values in this size range, highlighting the importance of the ASTERIA model for determining the surface TI of small asteroids  (see Figure). A general advantage of the ASTERIA model is that it may be applied to smaller asteroids than TPM, because the Yarkovsky effect is more substantial in smaller objects and, therefore, easier to detect. Additionally, TPM requires thermal infrared observations and good shape models, which are currently challenging for asteroids below some 100 m in size. Based on the astrometric measurements and the detection of Yarkovsky-induced acceleration of orbital motion, it is primarily independent of the most widely used approach for the asteroid TI estimations based on TPM. As such, ASTERIA may also serve as a benchmark test to independently verify the results derived from TPM, one of the long-standing challenges of TPM models [3].References:[1] Novakovic, B., Fenucci, M., Marceta, D., and Pavela, D., 2024, PSJ, 5, 11.[2] Fenucci M., Novaković B., Marčeta D. and Pavela D. 2023 Fenu24/D-NEAs: ASTERIA v1.0.0 Zenodo, doi: 10.5281/zenodo.8365840[3] Hung D., Hanuš J., Masiero J.

Upgrading SPHERE with the second stage AO system SAXO+
Authors: Boccaletti Anthony
Published: July 2024

SAXO+ is a project to upgrade the SPHERE extreme Adaptive Optics instrument at the VLT to boost the current performances of detection and characterization of exoplanets and disks. The main science drivers are 1/ to access the bulk of the young giant planet population down to the snow line (3-10 au), to bridge the gap with complementary techniques (radial velocity, astrometry); and 2/ to observe fainter and redder targets in the youngest (1 − 10 Myr) associations compared to those observed with SPHERE to directly study the formation of giant planets in their birth environment.SAXO+ is a second stage AO system equipped with an IR pyramid wavefront sensor for increasing the sampling frequency (from ~1 to 3 kHz) as well as the sensitivity in the infrared (+2-3 mag). SAXO+ is developed in coordination with the ESO technology development group and will serve as a demonstrator for the future planet finder (PCS) of the ELT. SAXO+ has concluded its consolidation phase in Apr 2024 and will continue its development to aim for on-sky testing in 2027. After introducing the science cases, we will discuss the SAXO+ project in particular the system choices and the estimation of performances based on the most recent simulations (see Figure). Figure : Raw contrast estimated for SPHERE (square sympols) and SAXO+ (asterisque symbols) for several target properties (B for bright targets, R for red targets) and assuming 0.7'' seeing and tau_0=5.5ms.
Modelling phase errors induced by multilayer optical coating using Monte Carlo transmission line modelling and PAOS for performance sensitivity of the Ariel mission

Published: July 2024

The Ariel space mission requires the simultaneous observation of exoplanet systems in visible and infrared wavelengths through spectroscopic and photometric channels. These wavebands are selected and isolated using dichroic beamsplitters. Dichroic beamsplitters, or dichroics, are filters that rely on the optical interference occurring within thin film layers to ensure the transmission and reflection of selective wavelengths from an incident light beam. They aim to facilitate a predetermined pathway of different wavebands by manipulating the separation of precise ranges of wavelengths and play a role in determining the spectral response of an instrument.The assumption that the layers of coating that comprise the dichroic are entirely uniform may pose a significant limitation to its physical accuracy. Complex dichroic coatings can exhibit phase effects in both transmission and reflection of light, affecting the WaveFront Error (WFE) and, consequently, the point spread function (PSF) as a function of the wavelength. The deviations in the phase observed across the surface of the dichroic are primarily the result of variations in the thickness of a given coating layer, influenced by the accuracy of the technique and equipment used during the deposition process of the coatings.Here, we use transmission-line modelling to explore the effect of low-spatial frequency variations in the thicknesses of the layers to assess the subsequent impact on the resulting phase of the outgoing beams of a dichroic. We apply our methodology to a case study of an example dichroic that has been designed to comply with the spectral requirements of Ariel’s extreme broadband dichroic, D1.We will show that these non-uniformities introduce a wavelength-dependent shift in the observed phases of the outgoing beam, which may subsequently degrade the PSF. We obtain estimates of the expected phase variations when subjected to low-spatial frequency errors in thickness. The physical distribution of these errors in the form of WFE maps are propagated through the optical chain of Ariel using PAOS, an open-source, generic Physical Optics Propagation code developed by Ariel scientists, to assess the consequent impact on the PSF at the focal plane of the FGS-2 photometer.
Radiation hydrodynamics of protoplanetary disks with frequency-dependent dust opacities

Published: July 2024

In protoplanetary disks of gas and dust, sub-micron interstellar grains must grow at least 13 orders of magnitude in size to become terrestrial planets. The frequency-dependent opacities of these silicate grains to pre-main-sequence stellar radiation affect the thermodynamic structure of the disk, which itself influences the various stages of planet formation and migration. With a reduced overall opacity skewed toward shorter wavelengths, the tenuous disk atmosphere heats up as dust preferentially absorbs ultraviolet rays from the young star, while settled grains make the disk midplane optically thick and cooler. Conventional disk and planet formation models, however, use simplified assumptions about the thermodynamic structure, including vertically isothermal temperature profiles, Planck- or Rosseland-mean dust opacities, and flux-limited-diffusion approximations to radiation transport valid only in optically thick regions. Thus, further development of more detailed and self-consistent disk profiles using multifrequency radiation hydrodynamics is warranted. We use the Athena++ finite-volume hydrodynamics code, extended with multigroup radiation transport, to develop and analyze new stellar-irradiated disk models that include the frequency-dependent opacities of silicate dust grains. As the radiation module neither assumes a diffusion-dominated limit nor treats the radiation field as another fluid, our models can better capture the full dynamic range in disk optical depths.
Women in Astronomy in Belgium

The under-representation of women in STEM (Science, Technology, Engineering and Mathematics) and astronomy is a fact that appears in multiple European countries, and has been extensively analyzed [1]. Female astronomers and women in STEM appear to face struggles throughout their academic career path, due to a combination of factors, like family formation, childbearing, expectations connected to gender, personal choices in lifestyle, career preferences, etc. [2].In Belgium too, this seems to still be the case. In an early study, [3] analysed gender-specific statistics on the Belgian physicists. One of the difficulties they found was that Belgium keeps different statistics for the French-speaking and Flemish universities, and the career structure is different depending on the Communities.In a preliminary work, we attempted to gather all information available to study the question of the representation of women in astronomy in Belgium, which was not a straightforward task [4].In this poster, we will present the results of a quantitative and qualitative study carried out within the frame of a thesis of the Advanced Master in Space Studies at the KU Leuven and Universiteit Gent. We conducted a survey addressing the Belgian astronomer community currently working or who have worked in public institutes, such as universities and federal institutes.References[1] European Commission, Directorate-General for Research and Innovation, She figures handbook 2021, Publications Office, 2021, https://data.europa.eu/doi/10.2777/003736[2] ​Ceci & Williams, Understanding current causes of women's underrepresentation in science, 2011-02, Vol.108 (8)[3] Petra Rudolf, Vice‐President, Christine Iserentant, Muriel Vander Donckt, Nathalie Balcaen, Peggy Fredrickx, Karen Janssens, and Griet Janssen, "Women in Physics in Belgium: Still a Long Way From Achieving Gender Equality", AIP Conference Proceedings 628, 131-132 (2002) https://doi.org/10.1063/1.1505297[4] Piccialli, A., Lefever, K., Carine Vandaele, A., et al., 2021, European Planetary Science Congress. doi:10.5194/epsc2021-58
