VINTERGATAN - I. The origins of chemically, kinematically, and structurally distinct discs in a simulated Milky Way-mass galaxy
Feuillet, Diane K.; Feltzing, Sofia; Ryde, Nils +6 more
Spectroscopic surveys of the Milky Way's stars have revealed spatial, chemical, and kinematical structures that encode its history. In this work, we study their origins using a cosmological zoom simulation, VINTERGATAN, of a Milky Way-mass disc galaxy. We find that in connection to the last major merger at z ∼ 1.5, cosmological accretion leads to …
Space weather: the solar perspective: An update to Schwenn (2006)
Temmer, Manuela
The Sun, as an active star, is the driver of energetic phenomena that structure interplanetary space and affect planetary atmospheres. The effects of Space Weather on Earth and the solar system is of increasing importance as human spaceflight is preparing for lunar and Mars missions. This review is focusing on the solar perspective of the Space We…
Reconstructing the Last Major Merger of the Milky Way with the H3 Survey
Conroy, Charlie; Ting, Yuan-Sen; Cargile, Phillip A. +8 more
Several lines of evidence suggest that the Milky Way underwent a major merger at z ~ 2 with the Gaia-Sausage-Enceladus (GSE) galaxy. Here we use H3 Survey data to argue that GSE entered the Galaxy on a retrograde orbit based on a population of highly retrograde stars with chemistry similar to the largely radial GSE debris. We present the first tai…
The Hubble Constant from Infrared Surface Brightness Fluctuation Distances
Ma, Chung-Pei; Greene, Jenny E.; Blakeslee, John P. +2 more
We present a measurement of the Hubble constant H0 from surface brightness fluctuation (SBF) distances for 63 bright, mainly early-type galaxies out to 100 Mpc observed with the WFC3/IR on the Hubble Space Telescope (HST). The sample is drawn from several independent HST imaging programs using the F110W bandpass, with the majority of th…
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…
