BCG C4 cluster catalog
Listed in IVOA Registry (Virtual Observatory)
We use the Sloan Digital Sky Survey (SDSS) to construct a sample of 625 brightest group and cluster galaxies (BCGs) together with control samples of non-BCGs matched in stellar mass, redshift and colour.
Description
We investigate how the systematic properties of BCGs depend on stellar mass and on their privileged location near the cluster centre. The groups and clusters that we study are drawn from the C4 catalogue of Miller et al. (2005, Cat. <J/AJ/130/968>) but we have developed improved algorithms for identifying the BCG and for measuring the cluster velocity dispersion.
Since the SDSS photometric pipeline tends to underestimate the luminosities of large galaxies in dense environments, we have developed a correction for this effect which can be readily applied to the published catalogue data.
