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

open access: yesEPJ 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.

A dynamical model for the heavily ram pressure stripped Virgo spiral galaxy NGC 4522 [PDF]

open access: yes, 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.

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

open access: yesEPJ 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.

Enrichment of the Intracluster Medium [PDF]

open access: yes, 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.

INTRACLUSTER MEDIUM OF THE MERGING CLUSTER A3395 [PDF]

open access: yesThe Astrophysical Journal, 2011
We present a detailed imaging and spectral analysis of the merging environment of the bimodal cluster A3395 using X-ray and radio observations. X-ray images of the cluster show five main constituents of diffuse emission : A3395 NE, A3395 SW, A3395 NW, A3395 W, and a filament connecting NE to W.

Stability analysis of convection in the intracluster medium [PDF]

open access: yesPhysics 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]

open access: yes, 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.

panco2: a Python library to measure intracluster medium pressure profiles from Sunyaev-Zeldovich observations

open access: yesThe Open Journal of Astrophysics, 2023
We present panco2, an open-source Python library designed to extract galaxy cluster pressure profiles from maps of the thermal Sunyaev-Zeldovich effect.

Chemical and Thermal History of the Intracluster Medium

open access: yes, 2004
Clusters of galaxies can be seen as giant astrophysical laboratories enclosing matter in a large enough volume, so that the matter composition can be taken as representing the composition of our Universe.
