Galactic coronae in the intracluster environment: semiconfined stellar-feedback-driven outflows
X-ray observations galaxies
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...

This work measures the evolution of the iron content in galaxy clusters by a rigorous analysis of the data of 130 clusters at 0.1is task is made difficult by a) the low signal-to-noise ratio...
Intracluster Medium reheating by relativistic jets
Intracluster Medium reheating by relativistic jets
2011/10/18
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...

Quasisteady Configurations Conductive Intracluster Media
2011/10/8
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 ...
Intracluster supernovae in the Multi-epoch Nearby Cluster Survey
Intracluster supernovae Multi-epoch Nearby Cluster Survey
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...
Non Thermal Support for the Outer Intracluster Medium
Non Thermal the Outer Intracluster Medium
2011/1/10
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...
Galactic Coronae in the Intracluster Environment: Semi-confined Stellar-feedback-driven Outflows
High Energy Astrophysical Phenomena (astro-ph.HE)
2010/12/24
Recently X-ray observations have shown the common presence of compact galactic coronae around intermediate-mass spheroid galaxies embedded in the intracluster/intragroup medium (ICM). We conduct 2-D h...
Heating of the Intracluster Medium by Quasar Outflows
theory Galaxies medium X-rays galaxies clusters
2009/5/19
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 Fate of Dwarf Galaxies in Clusters and the Origin of Intracluster Stars
Cosmology—galaxies clusters dwarfs interactions—methods numerical
2010/9/15
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...
