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 ...

A dynamical model for the heavily ram pressure stripped Virgo spiral galaxy NGC 4522 [PDF]
, 2006 A dynamical model including ram pressure stripping is applied to the strongly HI deficient Virgo spiral galaxy NGC 4522. A carefully chosen model snapshot is compared with existing VLA HI observations.

Understanding shape and centroid deviations in 39 strong lensing galaxy clusters in various dynamical states [PDF]
EPJ Web of ConferencesThrough observational tests of strong lensing galaxy clusters, we can test simulation derived structure predictions that follow from Λ Cold Dark Matter (ΛCDM) cosmology.

Power spectrum estimation methods on intracluster medium surface brightness fluctuations [PDF]
EPJ Web of ConferencesAccurate estimation of galaxy cluster masses is a central problem in cosmology. Turbulence is believed to introduce significant deviations from the hydrostatic mass estimates.

Enrichment of the Intracluster Medium [PDF]
, 1999 The relevance of galaxies of different luminosity and mass for the chemical enrichment of the intracluster medium (ICM) is analysed. For this purpose, I adopt the composite luminosity function of cluster galaxies from Trentham (1998), which exhibits a significant rise at the very faint end.

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--B nard 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.

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.
