Journal ArticleDOI
The environmental dependence of galaxy clustering in the Sloan Digital Sky Survey
Ummi Abbas,Ravi K. Sheth +1 more
TL;DR: In this article, the authors used a sample of galaxies drawn from the Sloan Digital Sky Survey (SDSS) to compare measurements of galaxy clustering in dense and underdense regions.
Journal ArticleDOI
AVOIDING PROGENITOR BIAS: THE STRUCTURAL AND MASS EVOLUTION OF BRIGHTEST GROUP AND CLUSTER GALAXIES IN HIERARCHICAL MODELS SINCE z ≲ 1
Francesco Shankar,Stewart Buchan,Alessandro Rettura,Vincent Bouillot,Jorge Moreno,Jorge Moreno,Rossella Licitra,Mariangela Bernardi,Marc Huertas-Company,Marc Huertas-Company,Simona Mei,Simona Mei,Simona Mei,Begoña Ascaso,Ravi K. Sheth,Lauriane Delaye,Anand Raichoor +16 more
TL;DR: In this article, a comparison between high-redshift and local data suggests a noticeable increase in stellar mass of a factor of ≳ 2 since z ~ 1, and of 2.5 in mean effective radius.
Journal ArticleDOI
How unusual are the Shapley Supercluster and the Sloan Great Wall
TL;DR: In this article, the Shapley superclusters and the Sloan Great Wall were used to study the formation and evolution of the primordial fluctuation field in the local universe, and extreme value statistics were used for studying the largest structures in the universe.
Journal ArticleDOI
Halo model description of the non-linear dark matter power spectrum at k≫ 1 Mpc−1
TL;DR: In this article, the authors extended the halo-model formalism, including realistic substructure population within individual dark-matter haloes and the scatter of the concentration parameter at xed halo mass.
Journal ArticleDOI
The Morphological Butcher-Oemler effect in the SDSS Cut&Enhance Galaxy Cluster Catalog
Tomotsugu Goto,Sadanori Okamura,Masafumi Yagi,Ravi K. Sheth,Neta A. Bahcall,Shane A. Zabel,Michael S. Crouch,James Annis,Mariangela Bernardi,S. Chong,Percy Gomez,Sarah Hansen,Rita S. J. Kim,Adam Knudson,Timothy A. McKay,Christopher J. Miller,Maki Sekiguchi +16 more
TL;DR: In this paper, the evolution of the fraction of late type cluster galaxies as a function of redshift was investigated using one of the largest, most uniform cluster samples available, consisting of 514 clusters of galaxies in the range 0.02
