TL;DR: In this article, the angular correlation function for galaxies in four separate magnitude bins on angular scales ranging from 0003 to 15° is presented, with the mask accounting for regions of poor seeing, reddening, bright stars, etc.
Journal ArticleDOI
Early-type galaxies in the SDSS. I. The sample
Mariangela Bernardi,Ravi K. Sheth,J. Annis,Scott Burles,Daniel J. Eisenstein,D. P. Finkbeiner,David W. Hogg,Robert H. Lupton,David J. Schlegel,M. Subbarao +9 more
TL;DR: A sample of nearly 9000 early-type galaxies, in the redshift range 0.01 < z < 0.3, was selected from the Sloan Digital Sky Survey using morphological and spectral criteria as discussed by the authors.
Journal ArticleDOI
Detection of Cosmic Magnification with the Sloan Digital Sky Survey
Ryan Scranton,Brice Ménard,Gordon T. Richards,Robert C. Nichol,Adam D. Myers,Bhuvnesh Jain,Alex Gray,Matthias Bartelmann,Robert J. Brunner,Andrew J. Connolly,James E. Gunn,Ravi K. Sheth,Neta A. Bahcall,John Brinkman,Jon Loveday,Donald P. Schneider,Aniruddha R. Thakar,Donald G. York +17 more
TL;DR: In this paper, an 8 σ detection of cosmic magnification measured by the variation of quasar density due to gravitational lensing by foreground large-scale structure is presented, which is in good agreement with theoretical predictions based on the WMAP concordance cosmology.
Journal ArticleDOI
The luminosities, sizes and velocity dispersions of Brightest Cluster Galaxies: Implications for formation history
TL;DR: In this article, the size-luminosity relation of early-type brightest cluster galaxies (BCGs), Re √ L 0.88, is shown to be steeper than that for the bulk of the early type galaxy population.
Journal ArticleDOI
The Velocity Dispersion Function of Early-Type Galaxies
Ravi K. Sheth,Mariangela Bernardi,Paul L. Schechter,Scott Burles,Daniel J. Eisenstein,Douglas P. Finkbeiner,Douglas P. Finkbeiner,Joshua A. Frieman,Robert H. Lupton,David J. Schlegel,Mark SubbaRao,Kazuhiro Shimasaku,Neta A. Bahcall,J. Brinkmann,Željko Ivezić +14 more
TL;DR: In this article, the distribution of early-type galaxy velocity dispersions is measured using a sample drawn from the Sloan Digital Sky Survey database, and it is shown that the distribution is dominated by early type galaxies at velocities larger than 200 km s-1.
