Most clusters and groups of galaxies contain a giant elliptical galaxy in their centers that 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 an N-body simulation of a cluster of galaxies in a hierarchical cosmological model, we show that galaxy merging naturally produces a massive central galaxy with surface brightness and velocity dispersion profiles similar to those of… 
The central elliptical galaxy in fossil groups and formation of brightest cluster galaxies
We study the dominant central giant elliptical galaxies in “Fossil groups” using deep optical (R-band) and near infrared (Ks-band) photometry. These galaxies are as luminous as the brightest cluster
Early Formation and Late Merging of the Giant Galaxies
The most luminous galaxies in the present universe are found at the centers of the most massive dark matter halos: rich galaxy clusters. In the ΛCDM cosmology, such massive halo cores are present at
WITNESSING THE FORMATION OF A BRIGHTEST CLUSTER GALAXY IN A NEARBY X-RAY CLUSTER*
The central dominant galaxies in galaxy clusters constitute the most massive and luminous galaxies in the universe. Despite this, the formation of these brightest cluster galaxies (BCGs) and the
Dynamical Evolution of Galaxies in Clusters
Tidal forces acting on galaxies in clusters lead to a strong dynamical evolution. In order to quantify the amount of evolution, I run self-consistent N-body simulations of disk galaxies for a variety
The role of dry mergers for the formation and evolution of brightest cluster galaxies
Using a resimulation technique, we perform high-resolution cosmological simulations of dry mergers in a massive (1015 M ☉) galaxy cluster identified in the Millennium Run. Our initial conditions
The hierarchical formation of the brightest cluster galaxies
We use semi-analytic techniques to study the formation and evolution of brightest cluster galaxies (BCGs). We show the extreme hierarchical nature of these objects and discuss the limitations of
The Diffuse Light in Simulations of Galaxy Clusters
We study the properties of the diffuse light in galaxy clusters forming in a large hydrodynamical cosmological simulation of the Λ cold dark matter cosmology. The simulation includes a model for
THE SPIDERWEB GALAXY: A FORMING MASSIVE CLUSTER GALAXY AT z ∼ 2
We present a deep image of the radio galaxy MRC 1138262 taken with the Hubble Space Telescope(HST) at a redshift of . The galaxy is known to have properties of a cD galaxy progenitor and be
On the survival and destruction of spiral galaxies in clusters
We follow the evolution of disk galaxies within a cluster that forms hierarchically in a cold dark matter N-body simulation. At a redshift z=0.5 we select several dark matter halos that have quiet
Dissipationless Merging and the Assembly of Central Galaxies
We reanalyze the galaxy-mass correlation function measured by the Sloan Digital Sky Survey to obtain host dark matter halo masses at galaxy and galaxy-group scales. We extend the data to galaxy

The galaxies located at the centers of clusters of galaxies are the most luminous stellar systems in the universe, and explaining the origin of these remarkable objects is a major challenge for any

We use high-resolution simulations to study the formation and distribution of galaxies within a cluster that forms hierarchically. We follow both dark matter and a gas component that is subject to

High resolution N-body simulations show that the density profiles of dark matter halos formed in the standard CDM cosmogony can be fit accurately by scaling a simple “universal” profile. Regardless
