According to the galactic cannibalism model, cD galaxies are formed in the centre of galaxy clusters by merging of massive galaxies and accretion of smaller stellar systems; however, observational examples of the initial phases of this process are lacking. We have identified a strong candidate for this early stage of cD galaxy formation: a group of five elliptical galaxies in the core of the X-ray cluster C0337-2522 at redshift z = 0.59. With the aid of numerical simulations, in which the…

Galactic cannibalism and cold dark matter density profiles
Using N-body simulations, we show that the process of formation of the brightest cluster galaxy through dissipationless galactic cannibalism can affect the inner cluster dark matter density profile.
Collisionless evaporation from cluster elliptical galaxies A contributor to the intracluster stellar population
By means of simple numerical models we discuss whether collisionless stellar evaporation from cluster elliptical galaxies could be an effective mechanism for the production of intracluster stellar
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
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

Context. Early-type dwarf (dE) galaxies are the most common type of galaxies observed in the Universe. Their study has important cosmological implications because according to hierarchical galaxy
A multiple dry merger at z = 0.18: witnessing the assembly of a massive elliptical galaxy
Mergers of gas-poor galaxies, so-called dry mergers, may play a fundamental role in the assembly of the most massive galaxies, and therefore, in galaxy formation theories. Using the SDSS, we have
CANDELS observations of the structural properties of cluster galaxies at z = 1.62
We discuss the structural and morphological properties of galaxies in a z = 1.62 proto-cluster using near-IR imaging data from Hubble Space Telescope Wide Field Camera 3 data of the Cosmic Assembly

Aims. The aim of this work is to investigate the physical, structur al and evolutionary properties of old, passive galaxies at z> 1.4 and to place new constraints on massive galaxy formation and
We present simulations of dry-merger encounters between pairs of elliptical galaxies with dark matter halos. The aim of these simulations is to study the intergalactic (IG) stellar populations
Strong lensing in Abell 1703: constraints on the slope of the inner dark matter distribution
Properties of dark matter haloes can be probed observationally and numerically, and comparing both approaches provides ways to constrain cosmological models. When it comes to the inner part of galaxy


Galactic cannibalism. III. The morphological evolution of galaxies and clusters
We present a numerical simulation for the evolution of massive cluster galaxies due to the accretion of other galaxies, finding that after several accretions a bright ''normal'' galaxy begins to
The Demography of massive dark objects in galaxy centers
We construct dynamical models for a sample of 36 nearby galaxies with Hubble Space Telescope (HST) photometry and ground-based kinematics. The models assume that each galaxy is axisymmetric, with a
Galaxy merging, the fundamental plane of elliptical galaxies and the MBH-σ0 relation
We explore the effects of dissipationless merging on the Fundamental Plane of elliptical galaxies by using a N-body code based on a new, high performance numerical scheme (Dehnen 2002). We
Formation of Galactic Nuclei
We investigate a model in which galactic nuclei form via the coalescence of preexisting stellar systems containing supermassive black holes. Merger simulations are carried out using N-body algorithms

We present N-body simulations of galaxy groups embedded in a common halo of matter. We study the influence of the different initial conditions upon the evolution of the group and show that denser
Properties of cD Galaxies
cD galaxies are the most luminous galaxies in the universe. They are characterized by a surface brightness profile that falls off more slowly with radius than most elliptical galaxies. In most
