Galaxies living in rich environments are suffering different perturbations able to drastically
affect their evolution. Among these, ram pressure strip**, ie the pressure exerted by the …

We measure spectral indexes for 1823 galaxies in the Canadian Network for Observational
Cosmology 1 (CNOC1) sample of 15 X-ray luminous clusters at 0.18< z< 0.55 to investigate …

We consider several mechanisms that possibly affect the evolution of disk galaxies in
clusters using analytical models based on a hierarchical clustering scenario. We especially …

There are many processes that can transport gas from the galaxies to their environment and
enrich the environment in this way with metals. These metal enrichment processes have a …

Aims. We investigate the influence of ram-pressure strip** on the star formation and the
mass distribution in simulated spiral galaxies. Special emphasis is put on the question of …

We demonstrate that the high pressure of the hot intracluster medium (ICM) can trigger the
collapse of molecular clouds in a spiral galaxy, leading to a burst of star formation in the …

We study galaxy interactions in the large-scale environment around A2670, a massive (M
200=) and interacting galaxy cluster at z= 0.0763. We first characterize the environment of …

We identify four rare" jellyfish" galaxies in Hubble Space Telescope imagery of the major
merger cluster Abell 2744. These galaxies harbor trails of star-forming knots and filaments …

We present a high-resolution set of adiabatic binary galaxy cluster merger simulations using
FLASH. These are the highest resolution simulations to date of such mergers using an …

We present an analysis of a Suzaku observation of the link region between the galaxy
clusters A 399 and A 401. We obtained the metallicity of the intracluster medium (ICM) up to …
