Encounters of merger and accretion shocks in galaxy clusters and their effects on intracluster medium [PDF]
Monthly notices of the Royal Astronomical Society, 2020 Several types/classes of shocks naturally arise during formation and evolution of galaxy clusters. One such class is represented by accretion shocks, associated with deceleration of infalling baryons.

Dynamical heating of the X-ray emitting intracluster medium: the roles of merger shocks and turbulence dissipation [PDF]
Monthly notices of the Royal Astronomical Society, 2020 The diffuse plasma inside clusters of galaxies has X-ray emitting temperatures of a few keV. The physical mechanisms that heat this intracluster medium (ICM) to such temperatures include the accretion shock at the periphery of a galaxy cluster, the ...

Nonthermal support for the outer intracluster medium [PDF]
Astronomy & Astrophysics, 2010 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 expect this component to increase briskly during the cluster development for z<1/2, due to three factors.

Electron Reacceleration via Ion Cyclotron Waves in the Intracluster Medium
The Astrophysical Journal, 2023 In galaxy clusters, the intracluster medium (ICM) is expected to host a diffuse, long-lived, and invisible population of “fossil” cosmic-ray electrons (CRe) with 1–100 MeV energies.

The nature of the motions of multiphase filaments in the centers of galaxy clusters
Frontiers in Astronomy and Space Sciences, 2023 The intracluster medium (ICM) in the centers of galaxy clusters is heavily influenced by the “feedback” from supermassive black holes (SMBHs). Feedback can drive turbulence in the ICM and turbulent dissipation can potentially be an important source of ...

Calcium-rich Gap Transients: Solving the Calcium Conundrum in the Intracluster Medium [PDF]
, 2014 X-ray measurements suggest the abundance of Calcium in the intracluster medium is higher than can be explained using favored models for core-collapse and Type Ia supernovae alone.

Differential reddening in 48 globular clusters: An end to the quest for the intracluster medium [PDF]
Astronomy & AstrophysicsFor decades, it has been theorized that a tenuous but detectable intracluster medium should be present in globular clusters, which is continuously replenished by the gas and dust ejected by bright giants and periodically cleared by interactions with the ...

Universal thermodynamic properties of the intracluster medium over two decades in radius in the X-COP sample [PDF]
Astronomy & Astrophysics, 2018 Context. The hot plasma in a galaxy cluster is expected to be heated to high temperatures through shocks and adiabatic compression. The thermodynamical properties of the gas encode information on the processes leading to the thermalization of the gas in ...

Dynamical evolution of magnetic fields in the intracluster medium [PDF]
Monthly notices of the Royal Astronomical Society, 2019 We investigate the evolution of magnetic fields in galaxy clusters starting from constant primordial fields using highly resolved ($\approx \rm 4 ~kpc$) cosmological MHD simulations.

Modelling the Energy Spectra of Radio Relics
Galaxies, 2021 Radio relics are diffuse synchrotron sources that illuminate shock waves in the intracluster medium. In recent years, radio telescopes have provided detailed observations about relics.
