Formation of multiphase plasma in galactic haloes and an analogy to solar plasma

Frontiers in Astronomy and Space Sciences, 2023
Thermal instability (TI) potentially explains the origin of cold gas in the intracluster medium (ICM), which is heated sufficiently by AGN feedback. The Hα filaments seen in cluster cores provide strong motivation for TI.

Stability analysis of convection in the intracluster medium [PDF]

Physics Letters A, 2016
We use the machinery usually employed for studying the onset of Rayleigh--Bénard convection in hydro- and magnetohydro-dynamic settings to address the onset of convection induced by the magnetothermal instability and the heat-flux-buoyancy-driven-instability in the weakly-collisional magnetized plasma permeating the intracluster medium.

Mapping the intracluster medium temperature in the era of NIKA2 and MUSTANG-2 [PDF]

EPJ Web of Conferences, 2022
We present preliminary results from an on-going program that aims at mapping the intracluster medium (ICM) temperature of high redshift galaxy clusters from the MaDCoWS sample using a joint analysis of shallow X-ray data obtained by Chandra and high ...

Heating of the intracluster medium

The Astrophysical Journal, 1990
The gravitational interaction of the system of galaxies and the ICM are treated by fluctuation theory. Fluctuation theory seems to be more adequate to describe the gravitational interaction than local theories used up to now, because gravitation is a long-range force.

Power spectrum estimation methods on intracluster medium surface brightness fluctuations [PDF]

EPJ Web of Conferences
Accurate estimation of galaxy cluster masses is a central problem in cosmology. Turbulence is believed to introduce significant deviations from the hydrostatic mass estimates.

Gas Stripping of Dwarf Galaxies in Clusters of Galaxies [PDF]

, 2000
Many clusters of galaxies contain an appreciable amount of hot gas, the intracluster medium. As a consequence, gas will be stripped from galaxies that move through the inter cluster medium, if the ram pressure exceeds the internal gravitational force. We

Understanding shape and centroid deviations in 39 strong lensing galaxy clusters in various dynamical states [PDF]

EPJ Web of Conferences
Through observational tests of strong lensing galaxy clusters, we can test simulation derived structure predictions that follow from Λ Cold Dark Matter (ΛCDM) cosmology.

The Intracluster Medium in z > 1 Galaxy Clusters [PDF]

, 2000
The Chandra X-ray Observatory was used to obtain a 190 ks image of three high redshift galaxy clusters in one observation. The results of our analysis of these data are reported for the two z > 1 clusters in this Lynx field, including the most distant ...

Turbulence in the intracluster medium: simulations, observables & thermodynamics [PDF]

, 2019
We conduct two kinds of homogeneous isotropic turbulence simulations relevant for the intracluster medium (ICM): (i) pure turbulence runs without radiative cooling; (ii) turbulent heating$+$radiative cooling runs with global thermal balance.
