Brightest cluster galaxies in Abell clusters
Listed in IVOA Registry (Virtual Observatory)
We have obtained photometry and spectroscopy of 433 z<=0.08 brightest cluster galaxies (BCGs) in a full-sky survey of Abell clusters to construct a BCG sample suitable for probing deviations from the local Hubble flow.
Description
This sample allows us to explore the structural and photometric properties of BCGs at the present epoch, their location in their hosting galaxy clusters, and the effects of the cluster environment on their structure and evolution.
We revisit the L_m_-{alpha} relation for BCGs, which uses {alpha}, the log-slope of the BCG photometric curve of growth, to predict the metric luminosity in an aperture with 14.3kpc radius, L_m_, for use as a distance indicator. We measure central stellar velocity dispersions, {sigma}, of the BCGs.
