Journal ArticleDOI
redMaPPer I: Algorithm and SDSS DR8 Catalog
Eli S. Rykoff,Eduardo Rozo,Michael T. Busha,Michael T. Busha,Carlos E. Cunha,Alexis Finoguenov,August E. Evrard,Jiangang Hao,Benjamin P. Koester,Alexie Leauthaud,Brian Nord,Marguerite Pierre,Rachel M. Reddick,Rachel M. Reddick,T. Sadibekova,Erin S. Sheldon,Risa H. Wechsler,Risa H. Wechsler +17 more
TL;DR: RedMaPPer as discussed by the authors is a new red sequence cluster finder designed to make optimal use of ongoing and near-future large photometric surveys, which can iteratively self-train the red sequence model based on a minimal spectroscopic training sample.
Journal ArticleDOI
NEW CONSTRAINTS ON THE EVOLUTION OF THE STELLAR-TO-DARK MATTER CONNECTION: A COMBINED ANALYSIS OF GALAXY-GALAXY LENSING, CLUSTERING, AND STELLAR MASS FUNCTIONS FROM z = 0.2 to z = 1*
Alexie Leauthaud,Alexie Leauthaud,Alexie Leauthaud,Jeremy L. Tinker,Kevin Bundy,Peter Behroozi,Richard Massey,Jason Rhodes,Matthew R. George,Jean-Paul Kneib,Andrew J. Benson,Risa H. Wechsler,Michael T. Busha,Michael T. Busha,Peter Capak,Marina Cortês,O. Ilbert,Anton M. Koekemoer,Oliver Le Fevre,Simon J. Lilly,H. J. McCracken,Mara Salvato,Tim Schrabback,Tim Schrabback,Nick Scoville,Tristan L. Smith,James E. Taylor +26 more
TL;DR: In this paper, the authors performed a joint analysis of galaxy-galaxy weak lensing, galaxy spatial clustering, and galaxy number densities using a self-consistent theoretical framework.
Journal ArticleDOI
Gravitationally Consistent HALO Catalogs and Merger Trees for Precision Cosmology
Peter Behroozi,Peter Behroozi,Risa H. Wechsler,Risa H. Wechsler,Hao-Yi Wu,Hao-Yi Wu,Michael T. Busha,Anatoly Klypin,Joel R. Primack +8 more
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 time steps.
Journal ArticleDOI
Virial Scaling of Massive Dark Matter Halos: Why Clusters Prefer a High Normalization Cosmology
August E. Evrard,August E. Evrard,James Bialek,Michael T. Busha,Martin White,Salman Habib,Katrin Heitmann,Michael S. Warren,Elena Rasia,Giuseppe Tormen,Lauro Moscardini,Chris Power,Adrian Jenkins,Liang Gao,Carlos S. Frenk,Volker Springel,Simon D. M. White,Juerg Diemand +17 more
TL;DR: In this paper, the authors presented a precise estimate of the bulk virial scaling relation of halos formed via hierarchical clustering in an ensemble of simulated cold dark matter cosmologies.
Journal ArticleDOI

TL;DR: In this article, the authors presented a large catalog of optically selected galaxy clusters from the application of a new Gaussian Mixture Brightest Cluster Galaxy (GMBCG) algorithm to SDSS Data Release 7 data.
