Buzzard to Cardinal: Improved Mock Catalogs for Large Galaxy Surveys
Chun-Hao To,Joseph DeRose,Risa H. Wechsler,Eli S. Rykoff,Hao Wu,Susmita Adhikari,Elisabeth Krause,Eduardo Rozo,David H. Weinberg +8 more
TL;DR: In this paper , the authors presented the Cardinal mock galaxy catalogs, a new version of the Buzzard simulation that has been updated to support ongoing and future cosmological surveys, including DES, DESI, and LSST.
Journal ArticleDOI
Gravitationally Consistent Halo Catalogs and Merger Trees for Precision Cosmology
TL;DR: In this article, the authors present a new algorithm for generating merger trees and halo catalogs which explicitly ensures consistency of halo properties (mass, position, and velocity) across timesteps.

Brandon M. S. Erickson,Raminderjeet Singh,August E. Evrard,Matthew R. Becker,Michael T. Busha,Andrey V. Kravtsov,Suresh Marru,Marlon Pierce,Risa H. Wechsler +8 more
TL;DR: In this article, the authors used XSEDE resources to produce multiple synthetic sky surveys of galaxies and large-scale structure in support of science analysis for the Dark Energy Survey.
Journal ArticleDOI
Anisotropic Satellite Galaxy Quenching: A Unique Signature of Energetic Feedback by Supermassive Black Holes?
TL;DR: In this paper , anisotropic satellite galaxy quenching (ASGQ) has been found in observational data and cosmological simulations and it has been shown that satellite galaxies along the major axis of the dark matter halo tend to have been accreted at earlier cosmic times and are hosted by subhalos of larger peak halo masses.
