Brightest Members of Clusters of Galaxies
Nature, 1969THERE are two opposing interpretations of the small dispersion σ1∼0.35 mag in the absolute magnitudes M1 of the brightest members of rich clusters of galaxies measured by Sandage1. In one view, advanced, among others, by Peebles2,3, it is assumed that there is a universal cluster luminosity function, and that the value of σ1 and of the variation of M1 ...

“Radio–active” Brightest Cluster Galaxies
2008We present a sample of clusters drawn from the C4 cluster catalog of the Sloan Digital Sky Survey, where particular emphasis has been placed on the correct identification of the Brightest Cluster Galaxy (BCG) and the determination of the velocity dispersion within the virial radius.

Brightest cluster galaxies as probes of galaxy formation
Brightest group and cluster galaxies are the most massive galaxies in the Universe and reside at the centres of galaxy clusters. These galaxies push galaxy formation and evolution models to their limits, providing a strong test to our current paradigm of galaxy formation.openaire +1 more source
