Improving LSST Photometric Calibration with Gaia Data

Subjects: subject: Instrumentation and Methods for Astrophysics (astro-ph.IM)
subject: FOS: Physical sciences

description: We consider the possibility that the Gaia mission can supply data which will improve the photometric calibration of LSST. After outlining the LSST calibra- tion process and the information that will be available from Gaia, we explore two options for using Gaia data. The first is to use Gaia G-band photometry of selected stars, in conjunction with knowledge of the stellar parameters Teff, log g, and AV, and in some cases Z, to create photometric standards in the LSST u, g, r, i, z, and y bands. The accuracies of the resulting standard magnitudes are found to be insufficient to satisfy LSST requirements when generated from main sequence (MS) stars, but generally adequate from DA white dwarfs (WD). The second option is combine the LSST bandpasses into a synthetic Gaia G band, which is a close approximation to the real Gaia G band. This allows synthetic Gaia G photometry to be directly compared with actual Gaia G photometry at a level of accuracy which is useful for both verifying and improving LSST photometric calibration.

description: Scivil Citizen Science Networking Day 2022 - 15 Nov 2022  Finally, the time has come! More than three years after our first networking day, we are organizing a new networking and learning event at the BMCC Bruges on November 15. Just like the previous time, we offer you an inspiring keynote speaker, a series of fascinating talks and workshops on different aspects of citizen science and a pleasant networking lunch. Moreover, during this networking day, we will launch our latest guide on citizen science in education. Therefore, this networking event runs in parallel to the Digiwijs event for teachers. We hope to create an exciting cross-pollination between citizen science and education, both during the session 'citizen science in the classroom', and during the networking lunch. There will also be an extra focus on the topic of citizen science data, with lectures and workshops on data visualisation, data management, data-driven policy and privacy. During lunch, you can ask all your data questions at the Scivil stand, where data stewards of the Flemish Open Science Board (FOSB) will be happy to help you. During the keynote presentation, Margaret Gold will share her insights from the European Mutual Learning Exercise on Citizen Science.  Margaret Gold is coordinator of the Citizen Science Lab at the University of Leiden, a knowledge hub and project incubator for public participation in scientific research. She leads the Citizen Science programme within the Dutch Programme for Open Science (NPOS), leading to the creation of the Citizen Science Nederland Network. Margaret’s previous experiences include work at the European Citizen Science Association, working on the projects WeObserve, Landsense and EU-Citizen-Science as well as the Natural History Museum in London as Science Community Manager, leading online citizen science projects.

Jacquemontia crassifolia

description: Jacquemontia crassifolia Scheele Linnaea 21: 752 (1848). — Type: Brazil, Minas Gerais, Hartleben s.n. (not found). REMARKS The identity of J. crassifolia remains a mystery. Meisner (1869) suggested it might be related to J. evolvuloides. However, this species is not part of the species group studied here, as its protologue clearly states that its calyx has outer oblong sepals smaller than the inner ones, and that the inner sepals are obovate, with abrupt acuminate apex.

High-resolution image of HD 100546: asymmetric ring and upper limits to circumplanetary disk
Creators: name: Pineda, Jaime
Publisher: name: Zenodo
Year: 2018

description: We present long baseline ALMA observations of the 870um dust continuum adn CO (3--2) emission from the protoplanetary disk around the Herbig Ae/Be star HD\,100546, which is one of the few systems claimed to have two young embedded planets. We resolve the disk emission into an asymmetric ring between 20-40 au, but there is no detection of the circumplanetary disk (CPD) at the position of the claimed protoplanets. We compare the CO morphology and kinematics to the continuum emission, and present evidence for a spiral feature. We present upperlimits to the planetary mass and the CPD, and compare to results from previous numerical simulations to rule-out some models.

Kinematic evidence for an embedded protoplanet in a circumstellar disc
Creators: name: Pinte, Christophe
Publisher: name: Zenodo
Year: 2018

description: Discs of gas and dust surrounding young stars are the birthplace of planets. However, the direct detection of protoplanets forming within discs has proved elusive to date. We present the detection of a large, localized deviation from Keplerian velocity in the protoplanetary disc surrounding the young star HD 163296. The observed velocity pattern is consistent with the dynamical effect of a two-Jupiter-mass planet orbiting at a radius ~ 260 au from the star.
Spectroscopic and photometric variability of a CTTS: HQ Tau
Creators: name: Pouilly, Kim
Publisher: name: Zenodo
Year: 2018

description: We studied the spectroscopic and photometric variation of the Classical T Tauri Star (CTTS) HQ Tau. We used the spectroscopic data from ESPaDOnS, the echelle spectrometer mounted at the Canada-France-Hawaï Telescope (CFHT), and the photometric data from the Kepler K2 mission. We first determined HQ Tau's stellar parameters, using ZEEMAN code and CESTAM models. We then looked for a periodic variability in the HQ Tau's lightcurve and spectrum through periodogram analysis, radial velocity, veiling, and emission line study. Finally we interpret the results obtained and try to connect spectroscopic and photometric variability within the framework of magnetospheric accretion.

description: After a decade and a half of research motivated by the accelerating universe, theory and experiment have a reached a certain level of maturity. The development of theoretical models beyond Λ, or smooth dark energy, often called modified gravity, has led to broader insights into a path forward, and a host of observational and experimental tests have been developed. In this review we present the current state of the field and describe a framework for anticipating developments in the next decade. We identify the guiding principles for rigorous and consistent modifications of the standard model, and discuss the prospects for empirical tests. We begin by reviewing attempts to consistently modify Einstein gravity in the infrared, focusing on the notion that additional degrees of freedom introduced by the modification must screen themselves from local tests of gravity. We categorize screening mechanisms into three broad classes: mechanisms which become active in regions of high Newtonian potential, those in which first derivatives become important, and those for which second derivatives are important. Examples of the first class, such as f(R) gravity, employ the familiar chameleon or symmetron mechanisms, whereas examples of the last class are galileon and massive gravity theories, employing the Vainshtein mechanism. In each case, we describe the theories as effective theories. We describe experimental tests, summarizing laboratory and solar system tests and describing in some detail astrophysical and cosmological tests. We discuss future tests which will be sensitive to different signatures of new physics in the gravitational sector. Parts that are more relevant to theorists vs. observers/experimentalists are clearly indicated, in the hope that this will serve as a useful reference for both audiences, as well as helping those interested in bridging the gap between them.

description: We present the analysis of supernova remnants (SNRs) in the Large Magellanic Cloud (LMC) and their influence on the environment at far-infrared (FIR) and submillimeter wavelengths. We use new observations obtained with the {\it Herschel} Space Observatory and archival data obtained with the {\it Spitzer} Space Telescope, to make the first FIR atlas of these objects. The SNRs are not clearly discernible at FIR wavelengths, however their influence becomes apparent in maps of dust mass and dust temperature, which we constructed by fitting a modified black-body to the observed spectral energy distribution in each sightline. Most of the dust that is seen is pre-existing interstellar dust in which SNRs leave imprints. The temperature maps clearly reveal SNRs heating surrounding dust, while the mass maps indicate the removal of 3.7$^{+7.5}_{-2.5}$ M$_{\odot}$ of dust per SNR. This agrees with the calculations by others that significant amounts of dust are sputtered by SNRs. Under the assumption that dust is sputtered and not merely pushed away, we estimate a dust destruction rate in the LMC of $0.037^{+0.075}_{-0.025}$ M$_\odot$ yr$^{-1}$ due to SNRs, yielding an average lifetime for interstellar dust of $2^{+4.0}_{-1.3}\times10^7$ yr. We conclude that sputtering of dust by SNRs may be an important ingredient in models of galactic evolution, that supernovae may destroy more dust than they produce, and that they therefore may not be net producers of long lived dust in galaxies.

The inner disk structure of the classical T Tauri star LkCa 15
Creators: name: Alencar, Silvia
Publisher: name: Zenodo
Year: 2018

description: LkCa 15 is a classical T Tauri star surrounded by a transition disk fromwhich accretion is ongoing. We analysed quasi-simultaneous spectropolarimetric and photometric data obtained in two observing seasons, covering several stellar rotational periods. We characterized the star-disk interaction and derived the accretion flow properties and the magnetic field at the stellar surface. We determined the stellar rotation period of 5.7 days and show that the light curve presents a typical dipper behavior, suggesting the existence of an inner disk warp that eclipses the star periodically, which is a surprising configuration for a transition disk system with a 50 au inner hole. The spectroscopic variability indicates the presence of a highly inclined inner disk that interacts with the stellar magnetosphere, which contrasts with the observed moderate inclination of the outer disk and suggests a misalignment between the inner and outer disks of this interesting transition disk system.

description: We study implications of large lepton-quark-leptoquark couplings for direct leptoquark searches at Large Hadron Collider. We present all existing flavor constraints on the strength of these couplings assuming that leptoquarks under consideration interact exclusively with charged leptons and quarks of the same generation. We find that these leptoquarks can have sizeable couplings to the Standard Model fermions. This insures a self consistency of our study. We discuss the leptoquark production mechanisms at LHC and demonstrate the importance of inclusion of a t-channel pair production and, in particular, a single leptoquark production through a recast of an existing CMS search at LHC for the second generation leptoquark. Our recast yields the best direct limit on Yukawa coupling of the second generation leptoquark that couples to a muon and a strange quark to date.

Observing the evolution of exoplanet-forming disks at 0.01-10 au with gas, dust, and wind tracers
Creators: name: Banzatti, Andrea
Publisher: name: Zenodo
Year: 2018

description: I will present results from a multi-wavelength and multi-tracer campaign to observe the evolution of protoplanetary disks at 0.01-10 au at the time of exoplanet formation. The backbone of this work is the combined analysis of recent surveys of moderate-to-high-resolution spectroscopy (R ~ 700- 100,000) of molecular gas emission at infrared wavelengths (2.9-35 um), as collected from a suite of instruments on the ground and in space (VLT-CRIRES, VLT-VISIR, Spitzer-IRS, Keck-NIRSPEC, IRTF-iSHELL). I will present and discuss three major findings of this campaign, as published in a series of papers in the last few years: 1) the location and excitation of CO gas reveals the formation of disk cavities and gaps in the 0.01-10 au disk region, 2) these cavities show a large depletion of both dust and gas, with some structures that models propose to be related to planet-disk interactions, and 3) disk chemistry evolves during formation of these cavities, with inner disks being dried-up from their water. I will mention new directions that we are investigating in synergy with the kinematics and evolution of disk-dispersing winds, with new results from a survey of high-resolution [OI] spectra. (I'd be happy to focus more on a few specific aspects of this large multi-faceted work depending on what the SOC finds best for the session in which they wish me to speak)

We generalize an asymptotic expansion by Widom [22], which was known for symbols supported on an arc. We highlight applications of our results in the Circular Unitary Ensemble and in the study of Fredholm determinants associated to the sine kernel.

Is the ring inside or outside the planet?: The effect of planet migration on dust rings
Creators: name: Meru, Farzana
Publisher: name: Zenodo
Year: 2018

description: Planet migration can shape the evolution of planets in protoplanetary discs and ultimately move them towards the locations at which they are discovered. Currently we have no direct observational test to determine if a planet is migrating in a protoplanetary disc. We explore the formation and evolution of dust rings in the presence of low mass (12-60 M⊕) migrating planets. Through two dimensional hydrodynamical simulations using gas and dust we find that the importance of perturbations in the pressure profile interior and exterior to the planet varies for different particle sizes. For small sizes, the dust enhancement occurs interior to the planet whereas it is exterior to it for large particles. We predict that if the location of an observed dust ring in the midplane significantly shifts outwards as the wavelength is increased, this would be an observational signature of a migrating planet.
Conductance behavior in nanowires with spin-orbit interaction -- A numerical study

Publisher: name: arXiv

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: We consider electronic transport through semiconducting nanowires (W) with spin-orbit interaction (SOI), in a hybrid N-W-N setup where the wire is contacted by normal-metal leads (N). We investigate the conductance behavior of the system as a function of gate and bias voltage, magnetic field, wire length, temperature, and disorder. The transport calculations are performed numerically and are based on standard recursive Green's function techniques. In particular, we are interested in understanding if and how it is possible to deduce the strength of the SOI from the transport behavior. This is a very relevant question since so far no clear experimental observation in that direction has been produced. We find that the smoothness of the electrostatic potential profile between the contacts and the wire plays a crucial role, and we show that in realistic regimes the N-W-N setup may mask the effects of SOI, and a trivial behavior with apparent vanishing SOI is observed. We identify an optimal parameter regime, with neither too smooth nor too abrupt potentials, where the signature of SOI is best visible, with and without Fabry-Perot oscillations, and is most resilient to disorder and temperature effects.

A study of transition disk properties belonging to the cluster NGC 2264
Creators: name: Sousa, Alana
Publisher: name: Zenodo
Year: 2018

description: Disk holes are inferred from infrared observations of T Tauri stars, indicating the existence of a transitional phase between thick disks and debris disks. We searched for transition disk belonging to the young (~3Myr) cluster NGC 2264. Using parameters obtained in the observational multiwavelength campaign CSI2264 we characterized the accretion, disk and stellar parameters of transition disk candidates and compared them with systems with a full disk and diskless systems. We have modeled 409 T Tauri stars with the Hyperion SED code that allowed us to classify the systems as full disk (52\%), diskless (41\%) and transition disk candidate (7\%). The presence of a hole in the inner disk does not stop the accretion process, since 82\% of transition disk stars are accreting and show Halpha, UV excess and mass accretion rates at the same level as full disk systems. With the output parameters of the SED model we estimated the inner hole size and found sizes from 0.1 to 78AU for the transition disks. 34\% of transition disks present hole sizes that can be explained by photoevaporation from stellar radiation. The other accreting transition disks can be good candidates to have inner planets.
Search for $W' \to t\bar{b}$ in the lepton plus jets final state in proton-proton collisions at a centre-of-mass energy of $\sqrt{s}$ = 8 TeV with the ATLAS detector

description: A search for new charged massive gauge bosons, called $W'$, is performed with the ATLAS detector at the LHC, in proton-proton collisions at a centre-of-mass energy of $\sqrt{s}$ = 8 TeV, using a dataset corresponding to an integrated luminosity of 20.3 fb$^{-1}$. This analysis searches for $W'$ bosons in the $W' \to t\bar{b}$ decay channel in final states with electrons or muons, using a multivariate method based on boosted decision trees. The search covers masses between 0.5 and 3.0 TeV, for right-handed or left-handed $W'$ bosons. No significant deviation from the Standard Model expectation is observed and limits are set on the $W' \to t\bar{b}$ cross-section times branching ratio and on the $W'$-boson effective couplings as a function of the $W'$-boson mass using the CL$_s$ procedure. For a left-handed (right-handed) $W'$ boson, masses below 1.70 (1.92) TeV are excluded at 95% confidence level.

title: Erwartungshaltung der Universitätslehrenden an die operativen Fertigkeiten der Studienanfänger*innen im BSc Mathematik

description: Kurt Matyas, Vizerektor der TU Wien, und Michael Drmota, Dekan der Fakultät Mathematik und Geoinformation der TU Wien, thematisieren in ihrem offenen Brief vom Juni 2018 an Heinz Faßmann, den damaligen Bildungsminister, das Absinken mathematischer Fertigkeiten von Studienanfänger*innen. Laut Matyas und Drmota scheint es den Studienanfänger*innen besonders an operativen Kompetenzen zu fehlen. Um diese Problematik besser zu verstehen, untersucht die vorliegende Masterarbeit, welche Erwartungen Universitätslehrende der Universität Wien an die operativen Fertigkeiten der Studienanfänger*innen des BSc Mathematik haben. Es wurden dazu 89 operative Fertigkeiten, welche für die Schnittstelle Schule-Hochschule von Bedeutung sind, identifiziert und jeweils eine prototypische Aufgabe für diese entworfen. Anschließend wurden acht Expert*inneninterviews mit Universitätslehrenden, die in den Jahren 2017 bis 2019 zumindest eine Einführungsvorlesung im Rahmen des BSc Mathematik gehalten hatten, durchgeführt. Jedes Interview bestand aus zwei Teilen: Offene Fragen zur Erwartungshaltung und die Methode des Card-Sorting kamen zur Anwendung. Beim Card-Sorting Teil ordneten die Universitätslehrenden die prototypischen Aufgaben jenen Institutionen zu, an denen diese ihrer Meinung nach gelehrt und vermittelt werden sollen. Durch die Section Label Analysis (SLA) Methode konnten 29 operative Fertigkeiten an die Schule und eine operative Fertigkeit an die Universität verwiesen werden. Bei 59 operativen Fertigkeiten konnte kein Konsens gefunden werden.
description: Kurt Matyas, Vice Rector of TU Wien, and Michael Drmota, Dean of the Faculty of Mathematics and Geoinformation at TU Wien, address the decline in mathematical skills of first-year students in their open letter to Heinz Faßmann, then Minister of Education, in June 2018. According to Matyas and Drmota, first-year students seem to lack operational skills in particular. In order to develop a better understanding of this problem, this master's thesis investigates what expectations university teachers at the University of Vienna have of the operational skills of BSc Mathematics first-year students. For this purpose, 89 operational skills that are important for the school-university interface were identified and a prototypical task for each of them was designed. Then, eight expert interviews were conducted with university lecturers who had given at least one introductory lecture in the BSc Mathematics between 2017 and 2019. Each interview consisted of two parts: Open-ended questions on expectations and the card-sorting method were used. In the card-sorting part, the university lecturers assigned the prototypical tasks to the institutions where they thought they should be taught. Through the Section Label Analysis (SLA) method, 29 operational skills could be referred to school and one operational skill to university. For 59 operational skills, no consensus could be found.
A density functional theory based direct comparison of coherent tunnelling and electron hopping in redox-active single molecule junctions

description: For defining the conductance of single molecule junctions with a redox functionality in an electrochemical cell, two conceptually different electron transport mechanisms, namely coherent tunnelling and vibrationally induced hopping compete with each other, where implicit parameters of the setup such as the length of the molecule and the applied gate voltage decide which mechanism is the dominant one. Although coherent tunnelling is most efficiently described within Landauer theory, while the common theoretical treatment of electron hopping is based on Marcus theory, both theories are adequate for the processes they describe without introducing accuracy limiting approximations. For a direct comparison, however, it has to be ensured that the crucial quantities obtained from electronic structure calculations, i.e. the transmission function T(E) in Landauer theory, and the transfer integral V, the reorganisation energy $λ$ and the driving force $ΔG^0$ in Marcus theory, are derived from similar grounds as pointed out by Nitzan and co-workers in a series of publications. In this article our framework is a single particle picture, where we perform density functional theory calculations for the conductance corresponding to both transport mechanisms for junctions with the central molecule containing one, two or three Ruthenium centers, respectively, where we extrapolate our results in order to define the critical length for the transition point of the two regimes which we identify at 5.76 nm for this type of molecular wire. We also discuss trends in dependence on an electrochemically induced gate potential.
Observing variability in young stellar objects in the infrared
Creators: name: Stock, Camille
Publisher: name: Zenodo
Year: 2018

description: Young stellar objects (YSOs) are characterised by accretion of matter through disks and ejection through jets. Both mechanisms are closely associated, however, their link is still not completely understood. In the past, these processes have been considered steady. Most recent observations, supported by theoretical models, indicate, however, that they are mostly episodic for a large range of stellar masses and ages and play a fundamental role in protostellar evolution. We have been using spectroscopic and imaging data from VLTI/ISAAC and SINFONI from different epochs (2005 and 2013) in the NIR to probe the kinematic and dynamic properties of IRS54, a very low-mass YSO, (0.2 Msun, Lbol ~0.78Lsun, Class I YSO) in the J, H, and K bands. To investigate the variability, we used the line emission of [FeII] (at 1.257, 1.644 microns) and BrG (2.166 microns). Correcting for visual extinction (~16mag in 2005 and ~29mag in 2013), we calculated the mass accretion rate to be ~5 x 10^-9 Msun yr-1 in 2005 and ~1 x 10^-7 Msun yr-1 in 2013. We found that its large variability is due to episodic accretion, making IRS54 the lowest mass outbursting YSO ever detected.

Non-LTE atomic line formation in accretion disk around young stars
Creators: name: Tessore, Benjamin
Publisher: name: Zenodo
Year: 2018

description: The planets forming in the accretion disk of young stars are yet unseen by the new generation of instruments whereas their study is crucial for understanding the evolution of inner planetary systems. Analysis of stellar spectra provides good proxies for studying and detecting such planetary systems. However, disentangling the signal due to the planets and to the star in stellar spectra could be cumbersome. Therefore, detailed spectral synthesis in realistic simulations of star-planets-disk system are crucial for detecting planets and studying their evolution within the accretion region. This spectral synthesis requires the solution of a set of statistical equilibrium equations for the atomic species of interest. The cornerstone of non equilibrium lines formation is obtaining the levels populations pertaining to the atom for which the lines belong to. In this poster, I present how the non-LTE problem for multi-level atomic systems is implemented and solved in the Monte-Carlo code MCFOST.

description: Using modified Richardson-Lucy algorithm we reconstruct the primordial power spectrum (PPS) from Planck Cosmic Microwave Background (CMB) temperature anisotropy data. In our analysis we use different combinations of angular power spectra from Planck to reconstruct the shape of the primordial power spectrum and locate possible features. Performing an extensive error analysis we found the dip near $\ell\sim750-850$ represents the most prominent feature in the data. Feature near $\ell\sim1800-2000$ is detectable with high confidence only in 217 GHz spectrum and is apparently consequence of a small systematic as described in the revised Planck 2013 papers. Fixing the background cosmological parameters and the foreground nuisance parameters to their best fit baseline values, we report that the best fit power law primordial power spectrum is consistent with the reconstructed form of the PPS at 2$σ$ C.L. of the estimated errors (apart from the local features mentioned above). As a consistency test, we found the reconstructed primordial power spectrum from Planck temperature data can also substantially improve the fit to WMAP-9 angular power spectrum data (with respect to power-law form of the PPS) allowing an overall amplitude shift of $\sim2.5\%$. In this context low-$\ell$ and 100 GHz spectrum from Planck which have proper overlap in the multipole range with WMAP data found to be completely consistent with WMAP-9 (allowing amplitude shift). As another important result of our analysis we do report the evidence of gravitational lensing through the reconstruction analysis. Finally we present two smooth form of the PPS containing only the important features. These smooth forms of PPS can provide significant improvements in fitting the data (with respect to the power law PPS) and can be helpful to give hints for inflationary model building.

description: We study certain higher-spin chiral operators in N=2 superconformal field theories (SCFTs). In Lagrangian theories, or in theories related to Lagrangian theories by generalized Argyres-Seiberg-Gaiotto duality ("type A" theories in our classification), we give a simple superconformal representation theory proof that such operators do not exist. This argument is independent of the details of the superconformal index. We then use the index to show that if a theory is not of type A but has an N=2-preserving deformation by a relevant operator that takes it to a theory of this type in the infrared, the ultraviolet theory cannot have these higher-spin operators either. As an application of this discussion, we give a simple prescription to extract the 2a-c conformal anomaly directly from the superconformal index. We also comment on how this procedure works in the holographic limit.

An unbiased SPHERE-IFS Survey of Nearby Herbig Ae/Be Stars: Are All Group I Disks Transitional?
Creators: name: Ubeira Gabellini, Maria Giulia
Publisher: name: Zenodo
Year: 2018

description: Maaskant et al. (2013) have proposed a model in which the Herbig Ae/Be stars with the strongest far-infrared excesses (the Meeus et al. Group I sources) have large disk gaps (possibly opened by newly formed planets) and may thus be considered transitional. One strong prediction from this model is that the Group I sources should have a larger spatial extent (as seen in scattered light) than the Group II Herbig stars. Giving constraints on the existence of gaps is important also for the evolution of the inner disk, particularly concerning the study of the disk accretion. We have developed a novel algorithm (SADI) for the removal of speckles from near-infrared VLT/SPHERE Integral Field Spectrograph (IFS) data, based on the wavelength-dependent position of speckles and the independence from it of real features (disks asymmetries and companions). This algorithm allowed us to detect so far four new companion candidates and six disk structures in a sample of 23 nearby Herbig stars. The ratio between the number of disk detections over the total number of Group I and Group II targets are found to be significantly different, in agreement with the expectations from the Maaskant et al. model.

description: We study a common-pool resource game where the resource experiences failure with a probability that grows with the aggregate investment in the resource. To capture decision making under such uncertainty, we model each player's risk preference according to the value function from prospect theory. We show the existence and uniqueness of a pure Nash equilibrium when the players have heterogeneous risk preferences and under certain assumptions on the rate of return and failure probability of the resource. Greater competition, vis-a-vis the number of players, increases the failure probability at the Nash equilibrium; we quantify this effect by obtaining bounds on the ratio of the failure probability at the Nash equilibrium to the failure probability under investment by a single user. We further show that heterogeneity in attitudes towards loss aversion leads to higher failure probability of the resource at the equilibrium.

Dust-pileup at the dead-zone inner edge and implications for the disk shadow
Creators: name: Ueda, Takahiro
Publisher: name: Zenodo
Year: 2018

description: The dead-zone inner edge is a preferential site of rocky planetesimal formation via the dust-pileup followed by the streaming instability. We performed simulations of one-dimensional dust and gas disk evolution to investigate the properties of a dust-pileup at the dead-zone inner edge. We show that a strong dust-pileup at the dead-zone inner edge occurs only for conditions where the dimensionless stopping time of dust is much larger than the turbulence parameter alpha in the dead-zone. We found that if the critical fragmentation velocity of silicate dust is 1 m/s, alpha value in the dead-zone should be lower than 0.0003 to operate the dust-pileup. Using the dust distribution obtained above, we performed the radiative transfer simulations with RADMC-3D to construct models of the inner region of disks including the effect of the dust-pileup. We found that if dust concentrates on the dead-zone inner edge, the dust-pileup casts a shadow behind it, which could be extended to ~ 10 au. The shadow would be a useful tracer of the dust-pileup and we can constrain the turbulence strength through it. In this poster, I would like to discuss the observability of the shadow based on our results.

description: We analyze the 6.5yr all-sky data from the Fermi LAT restricted to gamma-ray photons with energies between 0.6-307.2GeV. Raw count maps show a superposition of diffuse and point-like emission structures and are subject to shot noise and instrumental artifacts. Using the D3PO inference algorithm, we model the observed photon counts as the sum of a diffuse and a point-like photon flux, convolved with the instrumental beam and subject to Poissonian shot noise. D3PO performs a Bayesian inference in this setting without the use of spatial or spectral templates;i.e., it removes the shot noise, deconvolves the instrumental response, and yields estimates for the two flux components separately. The non-parametric reconstruction uncovers the morphology of the diffuse photon flux up to several hundred GeV. We present an all-sky spectral index map for the diffuse component. We show that the diffuse gamma-ray flux can be described phenomenologically by only two distinct components: a soft component, presumably dominated by hadronic processes, tracing the dense, cold interstellar medium and a hard component, presumably dominated by leptonic interactions, following the hot and dilute medium and outflows such as the Fermi bubbles. A comparison of the soft component with the Galactic dust emission indicates that the dust-to-soft-gamma ratio in the interstellar medium decreases with latitude. The spectrally hard component exists in a thick Galactic disk and tends to flow out of the Galaxy at some locations. Furthermore, we find the angular power spectrum of the diffuse flux to roughly follow a power law with an index of 2.47 on large scales, independent of energy. Our first catalog of source candidates includes 3106 candidates of which we associate 1381(1897) with known sources from the 2nd(3rd) Fermi catalog. We observe gamma-ray emission in the direction of a few galaxy clusters hosting radio halos.
