Journal ArticleDOI
Rhapsody-G simulations: galaxy clusters as baryonic closed boxes and the covariance between hot gas and galaxies
Hao-Yi Wu,August E. Evrard,Oliver Hahn,Davide Martizzi,Romain Teyssier,Risa H. Wechsler,Risa H. Wechsler +6 more
TL;DR: In this article, the authors present evidence from RHAPSODY-G hydrodynamic simulations of massive galaxy clusters that the closed box expectation may hold to a surprising degree within the interior, non-linear regions of haloes.
Journal ArticleDOI

TL;DR: CosmoDC2 as discussed by the authors is the starting point for the second data challenge (DC2) carried out by the LSST Dark Energy Science Collaboration (LSST DESC), which is based on a trillionparticle, 4.225 Gpc^3 box cosmological N-body simulation, the ''Outer Rim'' run.
Journal ArticleDOI
The Correlated Formation Histories of Massive Galaxies and Their Dark Matter Halos
Jeremy L. Tinker,Matthew R. George,Alexie Leauthaud,Kevin Bundy,Alexis Finoguenov,Richard Massey,Jason Rhodes,Risa H. Wechsler,Risa H. Wechsler +8 more
TL;DR: In this paper, an intriguing correlation between the star formation activity of massive central galaxies, their stellar masses, and the large-scale environments of their group-mass halos was reported.
Journal ArticleDOI

TL;DR: In this paper, the authors constructed a complete catalog of LMC luminous red supergiants, the best candidates to undergo invisible core collapse, and collected catalogs of other candidates: less luminous RED supergiant, yellow supergiger, blue supergiant, luminous blue variable stars, and Wolf-Rayet stars.
