Implications of a Nonthermal Origin of the Excess EUV Emission from the Coma Cluster of Galaxies
, 1999 The inverse Compton (IC) interpretation of the excess EUV emission, that was recently reported from several clusters of galaxies, suggests that the amount of relativistic electrons in the intracluster medium is highly significant, W_e>10^{61} erg ...

Observations of magnetic fields in intracluster medium [PDF]
Proceedings of the International Astronomical Union, 2012 AbstractThe presence of μG-level magnetic fields associated with the intracluster medium of galaxy clusters is now widely acknowledged. Our knowledge of their properties has greatly improved in the recent years thanks to both new radio observations and the developments of new techniques to interpret data.

The Seeding of Cosmic Ray Electrons by Cluster Radio Galaxies: A Review
GalaxiesRadio galaxies in clusters of galaxies are a prominent reservoir of magnetic fields and of non-thermal particles, which become mixed with the intracluster medium.

Relativistic hydrodynamic jets in the intracluster medium [PDF]
Monthly Notices of the Royal Astronomical Society, 2017 We have performed the first three-dimensional relativistic hydrodynamic simulations of extragalactic jets of pure leptonic and baryonic plasma compositions propagating into a hydrostatic intracluster medium environment. The numerical simulations use a general equation of state for a multi-component relativistic gas which closely reproduces the Synge ...

Probing cluster environments of blazars through gamma-gamma absorption
, 2014 Most blazars are known to be hosted in giant elliptic galaxies, but their cluster environments have not been thoroughly investigated. Cluster environments may contain radiation fields of low-energy photons created by nearby galaxies and/or stars in the ...

The role of pressure anisotropy in the turbulent intracluster medium
, 2012 In low-density plasma environments, such as the intracluster medium (ICM), the Larmour frequency is much larger than the ion-ion collision frequency. In such a case, the thermal pressure becomes anisotropic with respect to the magnetic field orientation ...

The evolution of intracluster medium in stellar clusters [PDF]
Proceedings of the International Astronomical Union, 2019 AbstractStars in globular clusters lose mass through slow stellar winds that are retained by the stellar cluster and should contribute to build up a non-negligible intracluster medium over time. However, all the observations so far found only a negligible amount of gas in GCs.

Merger Shocks Enhance Quenching in Local Galaxy Clusters
The Astrophysical JournalWe report evidence for enhanced quenching in low-redshift galaxy clusters hosting radio relics. This effect is strongest for low-mass galaxies and is consistent with a rapid quenching of star formation.

, 2011 Cosmological shocks are a critical part of large-scale structure formation, and are responsible for heating the intracluster medium in galaxy clusters. In addition, they are also capable of accelerating non-thermal electrons and protons. In this work, we
