The offset of Brightest Cluster Galaxies from their parent cluster core
Abstract
A Brightest Cluster Galaxies (BCG) is the brightest galaxy in a cluster of hundreds to thousands of galaxies. These monsters are some of the biggest, brightest, and most massive galaxies in the universe. Characterizing a BCG can help discover more about galaxy evolution - the aging, evolution, merging history of galaxies. This project involves determining the separation of the peak of X-ray emission of the galaxy cluster, and the location of the BCG. We do this to characterize the system as being disturbed or undisturbed. We have found that 17% of the 23 systems we observed have large separations, and thus may have undergone a recent merging event. Preliminary results on the age, metallicity and kinematics of the BCGs with large and small systems will be compared and presented.
