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.

The Magnetothermal Instability in the Intracluster Medium [PDF]

The Astrophysical Journal, 2008
The electron mean free path in the intracluster medium (ICM) of galaxy clusters is much larger than the gyroradius; thus, heat is transported anisotropically along magnetic field lines. We show that the intracluster medium is unstable to the magnetothermal instability (MTI) using MHD simulations with anisotropic thermal conduction.

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 ...

Chemical Evolution of Galaxies and Intracluster Medium [PDF]

, 2002
In this series of lectures I discuss the basic principles and the modelling of the chemical evolution of galaxies. In particular, I present models for the chemical evolution of the Milky Way galaxy and compare them with the available observational data.

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.

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 ...

Intracluster Medium through three years of WMAP [PDF]

, 2006
Wilkinson Microwave Anisotropy Probe (WMAP) has provided us with the yet highest resolution all-sky maps of the Cosmic Microwave Background. As a result of thermal Sunyaev-Zel'dovich effect, clusters of galaxies are imprinted as tiny, poorly resolved ...

Signatures of Galaxy Formation in the Intracluster Medium [PDF]

The Astrophysical Journal, 2003
The intergalactic gas in groups and clusters of galaxies bears the indelible stamp of galaxy formation. We present a comparison between observations and simple theoretical models indicating that radiative cooling governs the entropy scale that sets the core radius of the intracluster medium.

Enrichment of the Hot Intracluster Medium: Observations [PDF]

Space Science Reviews, 2018
Four decades ago, the firm detection of an Fe-K emission feature in the X-ray spectrum of the Perseus cluster revealed the presence of iron in its hot intracluster medium (ICM). With more advanced missions successfully launched over the last 20 years, this discovery has been extended to many other metals and to the hot atmospheres of many other galaxy ...
