Intracluster Light in Nearby Galaxy Clusters: Relationship to the Halos of Brightest Cluster Galaxies
We present a detailed analysis of the surface brightness distribution of the brightest cluster galaxy (BCG) in each of 24 galaxy clusters at 0.03 < z < 0.13. We use two-dimensional profile fitting to model the surface brightness out to r = 300 kpc for each BCG, comparing r1/4, r1/n, and double r1/4 models. We obtain statistically superior fits using a two component model consisting of a pair of...
متن کاملIntracluster Light in Nearby Galaxy Clusters: I. Relationship to the Halos of Brightest Cluster Galaxies
We present a detailed analysis of the surface brightness distribution of the brightest cluster galaxy (BCG) in a sample of 24 galaxy clusters at 0.03 < z < 0.13. We use two-dimensional profile fitting to model the surface brightness out to r = 300 h−1 70 kpc for each BCG, comparing r 1/4, r1/n, and double r1/4 models. The observed position angle and ellipticity gradients are inconsistent with a...
متن کاملAn imaging survey of a uniform sample of Brightest Cluster Galaxies and Intracluster Light
We present deep, large area B and r imaging for a sample of 49 brightest cluster galaxies (BCGs). The clusters were selected by their x-ray luminosity and redshift to form two volume limited samples, one with 〈z〉 ∼ 0.07 and one at 〈z〉 ∼ 0.17. For each cluster the data cover 41 × 41. We discuss our data reduction techniques in detail, and show that we can reliably measure the surface brightness ...
متن کاملThe Origin of the Brightest Cluster Galaxies
Most clusters and groups of galaxies contain a giant elliptical galaxy in their centres which far outshines and outweighs normal ellipticals. The origin of these brightest cluster galaxies is intimately related to the collapse and formation of the cluster. Using a large cosmological N-body simulation of cluster collapse, we show how hierarchical merging naturally produces a giant, central ellip...
متن کاملMorphological evolution of galaxies over the last 8 billion years
In this chapter I describe the motivation behind this Thesis work. I briefly review the main theoretical aspects and the very broad observational scenario, explaining the fundamental goals of this work and summarizing its most relevant contributions to the study of galaxy evolution. The review of previous work, both observational and theoretical, is by no means to be intended as exhaustive nor ...
