= Brightest cluster galaxy
{wiki=Brightest_cluster_galaxy}
The Brightest Cluster Galaxy (BCG) is typically the most luminous galaxy located at the center of a galaxy cluster. BCGs are generally giant elliptical galaxies that can often be found at the center of clusters due to the gravitational effects of the cluster's mass. They are important in the study of galaxy evolution and cluster dynamics because they can provide insights into the history and formation of the cluster itself.
