The evolution of substructure embedded in non-dissipative dark haloes is studied through N-body simulations of isolated systems, both in and out of initial equilibrium, complementing cosmological simulations of the growth of structure. We determine by both analytic calculations and direct analysis of the N-body simulations the relative importance of various dynamical processes acting on the clumps, such as the removal of material by global tides, clump–clump heating, clump–clump merging and… Expand
Galactic cannibalism in the galaxy cluster c0337-2522 at z=0.59
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, observationalExpand
Orbital parameters of infalling dark matter substructures
We present distributions of the orbital parameters of dark matter substructures at the time of merging into their host halo. Accurate knowledge of the orbits of dark matter substructures is a crucialExpand
On the dynamics of the satellite galaxies in NGC 5044
The NGC 5044 galaxy group is dominated by a luminous elliptical galaxy that is surrounded by ∼160 dwarf satellites. The projected number density profile of this dwarf population deviates within ∼1/3Expand
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.Expand
The concentration-velocity dispersion relation in galaxy groups
Based on results from cold dark matter N-body simulations, we develop a dynamical model for the evolution of subhaloes within group-sized host haloes. Only subhaloes more massive than 5 x 10(8)Expand
Long-lived triaxiality in the dynamically old elliptical galaxy NGC 4365: a limit on chaos and black hole mass
Supermassive black holes in the centres of giant elliptical galaxies are thought to be capable of inducing chaos and eliminating or preventing triaxiality in their hosts if they are sufficientlyExpand
On the life and death of satellite haloes
We study the evolution of dark matter satellites orbiting inside more massive haloes using semi-analytical tools coupled with high-resolution N-body simulations. We select initial satellite sizes,Expand
We present a theoretical formalism by which the global and the local mass functions of dark matter substructures (dark subhalos) can be analytically estimated. The global subhalo mass function isExpand
Absence of Dwarf Galaxies at High Redshifts: Evidence from a Galaxy Group
The galaxy group NGC 5044 consists of a luminous giant elliptical galaxy surrounded by a cluster of approximately 160 low luminosity and dwarf galaxies, mostly of early type. The cumulative projectedExpand
The Formalism for the Subhalo Mass Function in the Tidal-Limit Approximation
We present a theoretical formalism by which the global and local mass functions of dark matter substructures (dark subhalos) can be analytically estimated. The global subhalo mass function is definedExpand


The formation of disc galaxies
We investigate the influence of the cooling epoch on the formation of galaxies in a cold dark matter dominated universe. Isolated haloes, with circular speeds typical of spiral galaxies, have beenExpand

ABSTRA C T We investigate a model of disc galaxies whereby viscous evolution of the gaseous disc drives material inwards to form a protobulge. We start from the standard picture of disc formationExpand
