Brightest Cluster Galaxy Formation in Low - Redshift Galaxy Clusters
We present the composite luminosity function of a sample of 17 low-redshift galaxy clusters. Our luminosity functions have been measured for an inner region (r ≤ r 200) and an outer region (r 200 ≤ r ≤ 2r 200) centred on each Brightest Cluster Galaxy. The inner region luminosity function has a significantly flatter faint-end slope (α inner = −1.81 ± 0.02) than the outer region (α outer = −2.07 ...
متن کاملThe Correlation Function of Optically Selected Galaxy Clusters in the Sloan Digital Sky Survey
We measure the two-point spatial correlation function for clusters selected from the photometric MaxBCG galaxy cluster catalog for the Sloan Digital Sky Survey (SDSS). We evaluate the correlation function for several cluster samples using different cuts in cluster richness. Fitting the results to power-laws, ξcc(r) = (r/R0) , the estimated correlation length R0 as a function of richness is broa...
متن کاملShallow dark matter cusps in galaxy clusters
We study the evolution of the stellar and dark matter components in a galaxy cluster of 1015 M from z = 3 to the present epoch using the high-resolution collisionless simulations of Ruszkowski & Springel. At z = 3 the dominant progenitor haloes were populated with spherical model galaxies with and without accounting for adiabatic contraction. We apply a weighting scheme which allows us to chang...
متن کاملA MaxBCG Catalog of 13,823 Galaxy Clusters from the Sloan Digital Sky Survey
We present a catalog of galaxy clusters selected using the maxBCG redsequence method from Sloan Digital Sky Survey photometric data. This catalog includes 13,823 clusters with velocity dispersions greater than ≈400 km s, and is the largest galaxy cluster catalog assembled to date. They are selected in an approximately volume-limited way from a 0.5 Gpc region covering 7500 square degrees of sky ...
متن کاملBivariate galaxy luminosity functions in the Sloan Digital Sky Survey
Bivariate luminosity functions (LFs) are computed for galaxies in the New York Value-Added Galaxy Catalogue, based on the Sloan Digital Sky Survey Data Release 4. The galaxy properties investigated are the morphological type, inverse concentration index, Sérsic index, absolute effective surface brightness (SB), reference frame colours, absolute radius, eClass spectral type, stellar mass and gal...
