2014/12/20
Recently X-ray observations have shown the regular presence of compact galactic coronae around intermediate-mass spheroid galaxies embedded in the intracluster/intragroup medium (ICM). We conduct 2D h...

Galactic jets are powerful energy sources reheating the intra-cluster medium in galaxy clusters. Their crucial role in the cosmic puzzle, motivated by observations, has been established by a great num...

The radial distributions of temperature, density, and gas entropy among cool-core clusters tend to be quite similar, suggesting that they have entered a quasi-steady state. If that state is regulated ...

2010/11/11
The Multi-Epoch Nearby Cluster Survey (MENeaCS) has discovered twenty-two cluster Type Ia
supernovae (SNe) in the 58 X-ray selected galaxy clusters (0.05. z .0.15) surveyed. Four of our
SN Ia events...

We submit that non thermalized support for the outer intracluster medium in relaxed galaxy clusters is provided by turbulence, driven by inflows of intergalactic gas across the virial accretion shocks...

We study the possibility of quasar outflows in clusters and
groups of galaxies heating the intracluster gas in order to explain the recent
observation of excess entropy in this gas. We show that rad...

The main goal of this paper is to compare the relative importance of destruction by tides vs. destruction by mergers, in order to assess if tidal destruction of galaxies in clusters is a viable scenar...
