چکیده

Rich clusters of galaxies are interesting as the most massive gravitationally bound objects in the Universe. Although containing only about 1 % of all galaxies, they provide an environment for the formation and evolution of galaxies that is unique, and in many regards, the population of galaxies seen today in rich clusters di ers from that found in the eld. We therefore propose to complement the DRM programs that are targeted at eld galaxies with similar observations of 20 rich clusters (or their progenitors) at 1 < z < 5.

Stellar Populations in the Central Galaxies of Fossil Groups

It is inferred from the symmetrical and luminous X-ray emission of fossil groups that they are mature, relaxed galaxy systems. Cosmological simulations and observations focusing on their dark halo and inter-galactic medium properties confirm their early formation. Recent photometric observations suggest that, unlike the majority of non-fossil brightest group galaxies (BGGs), the central early-t...

Star cluster dynamics in galaxies

I present a review of star cluster (SC) dynamics in galaxies, with special emphasis on the effects of global galactic dynamics on SC formation and evolution. I particularly discuss (i) dynamical friction processes affecting SCs in galaxies of different masses, (ii) formation of stellar galactic nuclei and massive globular clusters (GCs) through multiple merging of SCs, (iii) interactions betwee...

Scaling relations in dynamical evolution of star clusters

We have carried out a series of small scale collisional N-body calculations of single-mass star clusters to investigate the dependence of the lifetime of star clusters on their initial parameters. Our models move through an external galaxy potential with a logarithmic density profile and they are limited by a cut-off radius. In order to find scaling relations between the lifetime of star cluste...

Group-cluster Merging and the Formation of Starburst Galaxies

A significant fraction of clusters of galaxies are observed to have substructure, which implies that merging between clusters and subclusters is a rather common physical process of cluster formation. It still remains unclear how cluster merging affects the evolution of cluster member galaxies. We report the results of numerical simulations, which show the dynamical evolution of a gas-rich late-...

Environmental Effects on Evolution of Cluster Galaxies in a Λcdm Universe

We investigate environmental effects on evolution of cluster galaxies under hierarchical structure formation scenario using combination of a dissipationless N-body simulation and a semi-analytic model of galaxy formation. The N-body simulation enables us to calculate orbits of galaxies in simulated clusters. Therefore we can include stripping of cold gas from the galactic disks by ram pressure ...
