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

Until recently, only about 10% of the total intracluster gas volume had been studied with high
accuracy, leaving a vast region essentially unexplored. This is now changing and a wide …

We use a large suite of carefully controlled full hydrodynamic simulations to study the ram
pressure stripping of the hot gaseous haloes of galaxies as they fall into massive groups and …

Context. Observationally, the quenching of star-forming galaxies appears to depend both on
their mass and environment. The exact cause of the environmental dependence is still …

Context. The hierarchical model of galaxy formation, despite its many successes, still
overpredicts the baryons fraction locked in galaxies as a condensed phase. The efficiency of …

Aims. We investigate the dependence of star formation and the distribution of the
components of galaxies on the strength of ram pressure. Several mock observations in X …

The hot intra-cluster medium (ICM) permeating galaxy clusters and groups is not pristine, as
it has been continuously enriched by metals synthesised in Type Ia (SNIa) and core …

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

We develop a model for the metal enrichment of the intracluster medium (ICM) that
combines a cosmological non-radiative hydrodynamical N-body/SPH (smoothed particle …

Weak lensing work can be badly compromised by unlensed foreground and cluster
members which dilute the true lensing signal. We show how the lensing amplitude in …
