description: IRAS 16293-2422 is a well studied low-mass protostar characterized by a strong level of deuterium fractionation. In the line of sight of the protostellar envelope, an additional absorption layer, rich in singly and doubly deuterated water has been discovered by a detailed multiline analysis of HDO. To model the chemistry in this source, the gas-grain chemical code Nautilus has been used with an extended deuterium network. For the protostellar envelope, we solve the chemical reaction network in infalling fluid parcels in a protostellar core model. For the foreground cloud, we explored several physical conditions (density, cosmic ionization rate, C/O ratio). The main results of the paper are that gas-phase abundances of H2O, HDO and D2O observed in the inner regions of IRAS16293-2422 are lower than those predicted by a 1D dynamical/chemical (hot corino) model in which the ices are fully evaporated. The abundance in the outer part of the envelope present chaotic profiles due to adsorption/evaporation competition, very different from the constant abundance assumed for the analysis of the observations. We also found that the large abundances of gas-phase H2O, HDO and D2O observed in the absorption layer are more likely explained by exothermic surface reactions rather than photodesorption processes.

Many body localization and delocalization in the two dimensional continuum

description: I discuss whether localization in the two dimensional continuum can be stable in the presence of short range interactions. I conclude that, for an impurity model of disorder, if the system is prepared below a critical temperature $T < T_c$, then perturbation theory about the localized phase converges almost everywhere. As a result, the system is at least asymptotically localized, and perhaps even truly many body localized, depending on how certain rare regions behave. Meanwhile, for $T > T_c$, perturbation theory fails to converge, which I interpret as interaction mediated delocalization. I calculate the boundary of the region of perturbative stability of localization in the interaction strength - temperature plane. I also discuss the behavior in a speckle disorder (relevant for cold atoms experiments) and conclude that perturbation theory about the non-interacting phase diverges for arbitrarily weak interactions with speckle disorder, suggesting that many body localization in the two dimensional continuum cannot survive away from the impurity limit.

description: We report the discovery of a giant stellar tidal stream in the halo of NGC 4631, a nearby edge-on spiral galaxy interacting with the spiral NGC 4656, in deep images taken with a 40-cm aperture robotic telescope. The stream has two components: a bridge-like feature extended between NGC 4631 and NGC 4656 (stream_SE) and an overdensity with extended features on the opposite side of the NGC 4631 disk (stream_NW). Together, these features extend more than 85 kpc and display a clear (g-r) colour gradient. The orientation of stream_SE relative to the orientations of NGC 4631 and NGC 4656 is not consistent with an origin from interaction between these two spirals, and is more likely debris from a satellite encounter. The stellar tidal features can be qualitatively reproduced in an N-body model of the tidal disruption of a single, massive dwarf satellite on a moderately eccentric orbit (e=0.6) around NGC 4631 over $\sim$ 3.5 Gyr, with a dynamical mass ratio (m1:m2) of ~40. Both modelling and inferences from the morphology of the streams indicate these are not associated with the complex HI tidal features observed between both spirals, which likely originate from a more recent, gas-rich accretion event. The detailed structure of stream_NW suggests it may contain the progenitor of the stream, in agreement with the N-body model. In addition, stream_NW is roughly aligned with two very faint dwarf spheroidal candidates. The system of dwarf galaxies and the tidal stream around NGC 4631 can provide an additional interesting case for exploring the anisotropy distribution of satellite galaxies recently reported in Local Group spiral galaxies by means of future follow-up observations.

Italian red zone

description: On February 2020,the Sars-Cov-2 reached Europe striking in Northern Italy.On February 21st, the police began to set manned checkpoints around quarantined towns: Codogno, Vo’Euganeo, and other 9 municipalities near Lodi district borders were renamed as “zone rosse” (red zones), and heavy mobility restrictions were applied”. The situation consequently has shaped the social media discourse: Facebook groups originally describing the peaceful daily life of the red zone became privileged arenas to understand the lockdownexperience. This paper aims at understanding if dark tourismactivities, defined as tripping to «places that either witnessed or represent death, destruction, suffering, or calamity (McDaniel, K., 2018, p.2), took place on the Facebook pages of the red zone cities, by analyzing the online behaviors and the interactions of out-of-towner people who joined these groups at the beginning of the lockdown period. Research design adopts a Digital Ethnography approach usingunobtrusive techniquesto test the paradigmatic application of digital methods. The results of our research aim to recreate the history of the action practiced through the Social Networks and will shed light on the culture and social implications of behaving and interacting online during an unforeseen event, like the COVD-19 pandemic
The AGN torus and beyond

description: A major advantage of ground-based thermal infrared observations is the increased angular resolution when compared to contemporary infrared space facilities. Even for the nearest active galactic nuclei (AGN), we need angular resolutions below 1" to probe their nuclear/circumnuclear regions (tens to hundreds of parsecs). The mid-infrared emission of AGN on those scales stems from the dusty torus, AGN polar emission and/or nuclear/circumnuclear star formation activity. In this talk I will review the most important results on the torus properties revealed with thermal infrared instruments on 8-10m class telescopes. I will discuss these results in the context of on-going ALMA and future JWST observations of the molecular gas and dust in the nuclear regions of nearby Seyfert galaxies.

description: Stellar population studies of globular clusters have suggested that the brightest clusters in the Galaxy might actually be the remnant nuclei of dwarf spheroidal galaxies. If the present Galactic globular clusters formed within larger stellar systems, they are likely surrounded by extra-tidal halos and/or tails made up of stars that were tidally stripped from their parent systems. The stellar surroundings around globular clusters are therefore one of the best places to look for the remnants of an ancient dwarf galaxy. Here an attempt is made to search for tidal debris around the supernovae enriched globular clusters M22 and NGC 1851 as well as the kinematically unique cluster NGC 3201. The stellar parameters from the Radial Velocity Experiment (RAVE) are used to identify stars with RAVE metallicities, radial velocities and elemental-abundances consistent with the abundance patterns and properties of the stars in M22, NGC 1851 and NGC 3201. The discovery of RAVE stars that may be associated with M22 and NGC 1851 are reported, some of which are at projected distances of ~10 degrees away from the core of these clusters. Numerous RAVE stars associated with NGC 3201 suggest that either the tidal radius of this cluster is underestimated, or that there are some unbound stars extending a few arc minutes from the edge of the cluster's radius. No further extra-tidal stars associated with NGC 3201 could be identified. The bright magnitudes of the RAVE stars make them easy targets for high resolution follow-up observations, allowing an eventual further chemical tagging to solidify (or exclude) stars outside the tidal radius of the cluster as tidal debris. In both our radial velocity histograms of the regions surrounding NGC 1851 and NGC 3201, a peak of stars at 230 km/s is seen, consistent with extended tidal debris from omega Centauri.

description: Абу Исхак Ибрахим б. Адхам ал-Балхи широко известен в мусульманской историографии как аскет, который жил в районе Балха в VIII в. Ранние источники изображают его сыном правителя Балха, который отказался от богатства мирской жизни и посвятил себя служению Богу. Наиболее важные из этих источников: «Табакат ас-суфийа» Абу ‘Абд ар-Рахмана ас-Сулами, «Хилйат ал-аулийа’» Абу Ну‘айма ал-Исфахани, «Табакат ас-суфийа» Абу ‘Абдаллаха Ансари, «Ар-Рисала фи-‘илм ат-тасаввуф» Абу-л-Касима ал-Кушайри, «Салват ал-‘арифин» Абу Халафа ат-Табари и «Райхан ал-хака’ик» Абу Бакра Мухаммада ад-Дарбанди. Здесь особенно важно проследить духовную преемственность ранней суфийской традиции: ад-Дарбанди получил иджазуот Абу Халафа ат-Табари, который, в свою очередь, был учеником Абу-л-Касима ал-Кушайри. Более поздние источники («Тазкират ал-аулийа’» Фарид ад-дина ‘Аттара, «Маснави» Руми и др.) показывают Ибрахима б. Адхама как правителя, который становится «святым». Преобразование образа святого, пришедшего из династии правителей Балха, можно четко проследить в миниатюрах школы Великих Моголов, резонируя с образами «святых правителей» династии Моголов, прежде всего с Ауренгзебом. Образ Ибрахима б. Адхама проник в Индию и Индонезию, где он приобрели дополнительные мифологические черты.Abu Iskhaq Ibrahim B. Adham al-Balkhi is well known in Muslim Historiography as the famous mystic and ascetic who lived in Balkh region in the 8th century. The early sources portray him as a ruler’s son who gave up riches of the worldly life and devoted himself to the service of God. The most important of these sources are: “Tabaqat as-sufiya” by Abu ‘Abd ar-Rahman as-Sulami, “Hilyat al-awliya” by Abu Nu‘aym al-Isfahani, “Tabaqat as-sufiya” by Abu ‘Abdallah Ansari, “Ar-Risala fi-‘ilm at-tasawwuf” by Abu ’l-Qasim al-Qushayri, “Salwat al-‘arifin” by Abu Khalaf at-Tabari and “Rayhan al-haqa’iq” by Abu Bakr Muhammad al-Darbandi. It is especially important to trace the spiritual continuity of the early Sufi tradition: ad-Darbandi received the written permission ( al-ijaza ) from Abu Khalaf at-Tabari, who was a disciple of Abu’l-Qasim al-Qushayri. The later sources (Farid ad-Din ‘Attar’s “Tadhkirat al-awliya”, Maulana Rumi’s “Masnawi”, etc.) show Ibrahim B. Adham as a ruler who becomes a saint. The transformation of the image of the saint, who came from the dynasty of the rulers of Balkh, can be clearly traced in the miniatures of the Mughal School, resonating with the images of the “holy rulers” of the Mughal dynasty. The image of Ibrahim B. Adham infiltrated to India and Indonesia, where it acquired additional mythological features.
Luminous Blue Variable stars as dust factories at sub-solar metallicities
Creators: name: Agliozzo, Claudia
Publisher: name: Zenodo
Year: 2020

description: Luminous Blue Variable stars are blue supergiants that undergo instabilities and experience outbursts with high mass-loss rates. An extreme example is eta Car, that in the XIX century ejected more than 40 solar masses at rates higher than 0.1 Msun/yr. Several Galactic LBVs exhibit extended circumstellar nebulae, often with large masses of dust (~0.01 Msun). How this dust is formed is not well understood, but the physical conditions in their ejecta during the giant eruptions seem favourable for the formation and growth of dust. Thus LBVs are candidate producers of dust in the early Universe, where massive stars were more numerous than at present.

description: We provide an algorithm for the construction of orthonormal multivariate polynomials that are symmetric with respect to the interchange of any two coordinates on the unit hypercube and are constrained to the hyperplane where the sum of the coordinates is one. These polynomials form a basis for the expansion of bosonic light-front momentum-space wave functions, as functions of longitudinal momentum, where momentum conservation guarantees that the fractions are on the interval $[0,1]$ and sum to one. This generalizes earlier work on three-boson wave functions to wave functions for arbitrarily many identical bosons. A simple application in two-dimensional $ϕ^4$ theory illustrates the use of these polynomials.

description: Information centric networking (ICN) proposes to redesign the Internet by replacing its host-centric design with information-centric design. Communication among entities is established at the naming level, with the receiver side (referred to as the Consumer) acting as the driving force behind content delivery, by interacting with the network through Interest message transmissions. One of the proposed advantages for ICN is its support for mobility, by de-coupling applications from transport semantics. However, so far, little research has been conducted to understand the interaction between ICN and mobility of consuming and producing applications, in protocols purely based on information-centric principles, particularly in the case of NDN. In this paper, we present our findings on the mobility-based performance of Named Data Networking (NDN) in wireless access networks. Through simulations, we show that the current NDN architecture is not efficient in handling mobility and architectural enhancements needs to be done to fully support mobility of Consumers and Producers.

description: A growing subset of Type Ia supernovae (SNe Ia) show evidence for unexpected interaction with a dense circumstellar medium (SNe Ia-CSM). The precise nature of the progenitor, however, remains debated owing to spectral ambiguities arising from a strong contribution from the CSM interaction. Late-time spectra offer potential insight if the post-shock cold, dense shell becomes sufficiently thin and/or the ejecta begin to cross the reverse shock. To date, few high-quality spectra of this kind exist. Here we report on the late-time optical and infrared spectra of the SNe~Ia-CSM 2012ca and 2013dn. These SNe Ia-CSM spectra exhibit low [Fe III]/[Fe II] ratios and strong [Ca II] at late epochs. Such characteristics are reminiscent of the super-Chandrasekhar-mass (SC) candidate SN 2009dc, for which these features suggested a low-ionisation state due to high densities, although the broad Fe features admittedly show similarities to the blue "quasi-continuum" observed in some core-collapse SNe Ibn and IIn. Neither SN 2012ca nor any of the other SNe Ia-CSM show evidence for broad oxygen, carbon, or magnesium in their spectra. Similar to the interacting Type IIn SN 2005ip, a number of high-ionisation lines are identified in SN 2012ca, including [S III], [Ar III], [Ar X], [Fe VIII], [Fe X], and possibly [Fe XI]. The total bolometric energy output does not exceed 10^51 erg, but does require a large kinetic-to-radiative conversion efficiency. All of these observations taken together suggest that SNe Ia-CSM are more consistent with a thermonuclear explosion than a core-collapse event, although detailed radiative transfer models are certainly necessary to confirm these results.

Challenges for mid-IR Instruments on ELTs
Creators: name: Brandl, Bernhard
Publisher: name: Zenodo
Year: 2020

description: I will briefly introduce the fundamental limitations of modern mid-IR facilities, both from ground and in space, and highlight their unique discovery spaces. I will generally discuss the unique challenges that ELTs impose on mid-IR instruments, from adaptive optics and high-contrast imaging to the complex thermal infrared background and and alternatives to classical chopping/nodding techniques. I will use the specific examples of the planned ELT instruments METIS (ELT) and MICHI (TMT) to illustrate how these challenges impact their conceptual design and capabilities.

description: Fort Sam Houston’s buildings exhibit a variety of architectural influences because of its incremental development. Its four posts, the Quadrangle and Staff Post, Infantry Post, Cavalry and Light Artillery Post, and New Post, are excellent visual records of the Army’s planning ideals and the architectural styles employed during their respective construction periods. The various architectural styles included Italianate, Colonial Revival, Mission/Spanish Colonial Revival, Greek Revival, Classical Revival, and Romanesque. In the Cavalry and Light Artillery Post, the Colonial Revival style was used widely in the design of buildings, including officers’ quarters, barracks, mess halls, and latrines. The Gift Chapel on the western end of the Cavalry and Light Artillery Post, however, is an example of Classical Revival architecture.

description: We report the sky-projected orbital obliquity (spin-orbit angle) of WASP-84b, a 0.70-$M_{\rm Jup}$ planet in a 8.52-day orbit around a G9V/K0V star, to be $λ= 0.3 \pm 1.7^\circ$. We obtain a true obliquity of $ψ= 14.8 \pm 8.0^\circ$ from a measurement of the inclination of the stellar spin axis with respect to the sky plane. Due to the young age and the weak tidal forcing of the system, we suggest that the orbit of WASP-84b is unlikely to have both realigned and circularised from the misaligned and/or eccentric orbit likely to have arisen from high-eccentricity migration. Therefore we conclude that the planet probably migrated via interaction with the protoplanetary disc. This would make it the first short-orbit, giant planet to have been shown to have migrated via this pathway. Further, we argue that the distribution of obliquities for planets orbiting cool stars ($T_{\rm eff}$ < 6250 K) suggests that high-eccentricity migration is an important pathway for the formation of short-orbit, giant planets.

Background subtraction in high-contrast imaging
Creators: name: Absil, Olivier
Publisher: name: Zenodo
Year: 2020

description: In this talk, I will describe the challenge of PSF subtraction in high-contrast imaging, and explain how it relates to the problem of background subtraction in thermal IR imaging. I will review the main image processing methods used in high-contrast imaging, and show that some of them can be readily adapted to the case of thermal IR background subtraction. I will also discuss some lessons learned on the operations of high-contrast imaging instruments, and how they could be applied to the case of thermal IR imaging.

Three-body bound states in a harmonic waveguide with cylindrical symmetry

Year: 2014
Subjects: subject: Quantum Gases (cond-mat.quant-gas)
subject: FOS: Physical sciences

description: Highly-elongated quasi-one-dimensional cold atom samples have been studied extensively over the past years experimentally and theoretically. This work determines the energy spectrum of two identical fermions and a third distinguishable particle as functions of the mass ratio $κ$ and the free-space $s$-wave scattering length $a_{3\text{D}}$ between the identical fermions and the distinguishable third particle in a cylindrically symmetric waveguide whose symmetry axis is chosen to be along the $z$-axis. We focus on the regime where the mass of the identical fermions is equal to or larger than that of the third distinguishable particle. Our theoretical framework accounts explicitly for the motion along the transverse confinement direction. In the regime where excitations in the transverse direction are absent (i.e., for states with projection quantum number $M_{\text{rel}}=0$), we determine the binding energies for states with odd parity in $z$. These full three-dimensional energies deviate significantly from those obtained within a strictly one-dimensional framework when the $s$-wave scattering length is of the order of or smaller than the oscillator length in the confinement direction. If transverse excitations are present, we predict the existence of a new class of universal three-body bound states with $|M_{\text{rel}}|=1$ and positive parity in $z$. These bound states arise on the positive $s$-wave scattering length side if the mass ratio $κ$ is sufficiently large. Implications of our results for ongoing cold atom experiments are discussed.

A relationship between specific star formation rate and metallicity gradient within z=1 galaxies from KMOS-HiZELS

description: We have observed a sample of typical z=1 star forming galaxies, selected from the HiZELS survey, with the new KMOS near-infrared, multi-IFU instrument on the VLT, in order to obtain their dynamics and metallicity gradients. The majority of our galaxies have a metallicity gradient consistent with being flat or negative (i.e. higher metallicity cores than outskirts). Intriguingly, we find a trend between metallicity gradient and specific star formation rate (sSFR), such that galaxies with a high sSFR tend to have relatively metal-poor centres, a result which is strengthened when combined with datasets from the literature. This result appears to explain the discrepancies reported between different high redshift studies and varying claims for evolution. From a galaxy evolution perspective, the trend we see would mean that a galaxy's sSFR is governed by the amount of metal poor gas that can be funnelled into its core, triggered either by merging or through efficient accretion. In fact merging may play a significant role as it is the starburst galaxies at all epochs, which have the more positive metallicity gradients. Our results may help to explain the origin of the fundamental metallicity relation, in which galaxies at a fixed mass are observed to have lower metallicities at higher star formation rates, especially if the metallicity is measured in an aperture encompassing only the central regions of the galaxy. Finally, we note that this study demonstrates the power of KMOS as an efficient instrument for large scale resolved galaxy surveys.
