Empirical Photometric Redshifts of Luminous Red Galaxies and Clusters in SDSS
In this work I discuss the necessary steps for deriving photometric redshifts for luminous red galaxies (LRGs) and galaxy clusters through simple empirical methods. The data used is from the Sloan Digital Sky Survey (SDSS). I show that with three bands only (gri) it is possible to achieve results as accurate as the ones obtained by other techniques, generally based on more filters. In particula...
متن کاملIntrinsic Ellipticity Correlation of Sdss Luminous Red Galaxies and Misalignment with Their Host Dark Matter Halos
We investigate the orientation correlation of giant elliptical galaxies by measuring the intrinsic ellipticity correlation function of 83,773 luminous red galaxies (LRGs) at redshifts 0.16 – 0.47 from the Sloan Digital Sky Survey. We have accurately determined the correlation up to 30 h Mpc. Luminosity dependence of the ellipticity correlation is also detected although the error bars are large,...
متن کاملCosmological parameter constraints from SDSS luminous red galaxies : a new treatment of large - scale clustering .
We apply a new model for the spherically averaged correlation function at large pair separations to the measurement of the clustering of luminous red galaxies (LRGs) made from the SDSS by Cabre & Gaztañaga (2009a). Our model takes into account the form of the BAO peak and the large scale shape of the correlation function. We perform a Monte Carlo Markov chain analysis for different combinations...
متن کاملLuminous red galaxies in hierarchical cosmologies
Luminous red galaxies (LRGs) are much rarer and more massive than L∗ galaxies. Coupled with their extreme colours, LRGs therefore provide a demanding testing ground for the physics of massive galaxy formation. We present the first self-consistent predictions for the abundance and properties of LRGs in hierarchical structure formation models. We test two published models which use quite differen...
متن کامل3d Genus Topology of Luminous Red Galaxies
We measure the 3D genus topology of large scale structure using Luminous Red Galaxies (LRGs) in the Sloan Digital Sky Survey and find it consistent with the Gaussian random phase initial conditions expected from the simplest scenarios of inflation. This studies 3D topology on the largest scales ever obtained. The topology is sponge-like. We measure topology in two volume-limited samples: a dens...
