Recommended conventions for reporting results from direct dark matter searches
Yang, Y.; Conrad, J.; Baxter, D. +23 more
The field of dark matter detection is a highly visible and highly competitive one. In this paper, we propose recommendations for presenting dark matter direct detection results particularly suited for weak-scale dark matter searches, although we believe the spirit of the recommendations can apply more broadly to searches for other dark matter cand…
KiDS-1000 catalogue: Weak gravitational lensing shear measurements
Hoekstra, Henk; Heymans, Catherine; Kuijken, Konrad +20 more
We present weak lensing shear catalogues from the fourth data release of the Kilo-Degree Survey, KiDS-1000, spanning 1006 square degrees of deep and high-resolution imaging. Our `gold-sample' of galaxies, with well-calibrated photometric redshift distributions, consists of 21 million galaxies with an effective number density of 6.17 galaxies per s…
TauREx 3: A Fast, Dynamic, and Extendable Framework for Retrievals
Waldmann, I. P.; Tinetti, G.; Changeat, Q. +1 more
TauREx 3 is the next generation of the TauREx exoplanet atmospheric retrieval framework for Windows, Mac, and Linux. It is a complete rewrite with a full Python stack that makes it easy-to-use, high-performance, dynamic, and flexible. The new main TauREx program is built with modularity in mind, allowing the user to augment its functionalities wit…
Rayleigh-Taylor and Richtmyer-Meshkov instabilities: A journey through scales
Zhou, Ye; Williams, Robin J. R.; Ramaprabhu, Praveen +9 more
Hydrodynamic instabilities such as Rayleigh-Taylor (RT) and Richtmyer-Meshkov (RM) instabilities usually appear in conjunction with the Kelvin-Helmholtz (KH) instability and are found in many natural phenomena and engineering applications. They frequently result in turbulent mixing, which has a major impact on the overall flow development and othe…
A Quick Look at the 3 GHz Radio Sky. I. Source Statistics from the Very Large Array Sky Survey
Safi-Harb, Samar; Baum, Stefi A.; O'Dea, Christopher P. +8 more
The Very Large Array Sky Survey (VLASS) is observing the entire sky north of -40° in the S band (2 GHz < ν < 4 GHz), with the highest angular resolution (2"5) of any all-sky radio continuum survey to date. VLASS will cover its entire footprint over three distinct epochs, the first of which has now been observed in full. Based on Quick Look i…
Updated BaSTI Stellar Evolution Models and Isochrones. II. α-enhanced Calculations
Salaris, Maurizio; Mucciarelli, Alessio; Silva Aguirre, Victor +7 more
This is the second paper of a series devoted to presenting an updated release of the BaSTI (a Bag of Stellar Tracks and Isochrones) stellar model and isochrone library. Following the publication of the updated solar-scaled library, here we present the library for an α-enhanced heavy element distribution. These new α-enhanced models account for all…
Quenched fractions in the IllustrisTNG simulations: comparison with observations and other theoretical models
Vogelsberger, Mark; Pillepich, Annalisa; Nelson, Dylan +3 more
We make an in-depth comparison of the IllustrisTNG cosmological simulations with observed quenched fractions of central and satellite galaxies, for Mstars = 109-12 M⊙ at 0 ≤ z ≤ 3. We show how measurement choices [aperture, quenched definition, and star formation rate (SFR) indicator time-scale], as well as sample …
Charting the Galactic Acceleration Field. I. A Search for Stellar Streams with Gaia DR2 and EDR3 with Follow-up from ESPaDOnS and UVES
Bianchini, Paolo; Martin, Nicolas; Malhan, Khyati +10 more
We present maps of the stellar streams detected in the Gaia Data Release 2 (DR2) and Early Data Release 3 (EDR3) catalogs using the STREAMFINDER algorithm. We also report the spectroscopic follow-up of the brighter DR2 stream members obtained with the high-resolution CFHT/ESPaDOnS and VLT/UVES spectrographs as well as with the medium-resolution NT…
The Field Substellar Mass Function Based on the Full-sky 20 pc Census of 525 L, T, and Y Dwarfs
Gonzales, Eileen C.; Kiman, Rocio; Meisner, Aaron M. +50 more
We present final Spitzer trigonometric parallaxes for 361 L, T, and Y dwarfs. We combine these with prior studies to build a list of 525 known L, T, and Y dwarfs within 20 pc of the Sun, 38 of which are presented here for the first time. Using published photometry and spectroscopy as well as our own follow-up, we present an array of color-magnitud…
The Evolutionary Map of the Universe pilot survey
Reiprich, Thomas H.; Koribalski, Bärbel S.; Norris, Ray P. +45 more
We present the data and initial results from the first pilot survey of the Evolutionary Map of the Universe (EMU), observed at 944 MHz with the Australian Square Kilometre Array Pathfinder (ASKAP) telescope. The survey covers $270 deg^2$ of an area covered by the Dark Energy Survey, reaching a depth of 25-30 $µJy beam^{-1}$ rms at a spatial …
