Measuring bulk flows of the intracluster medium in the Perseus and Coma galaxy clusters using XMM-Newton [PDF]

Astronomy & Astrophysics, 2019
We demonstrate a novel technique for calibrating the energy scale of the EPIC-pn detector on XMM-Newton, which allows us to measure bulk flows in the intracluster medium (ICM) of the Perseus and Coma galaxy clusters.

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.

Imprints of mass accretion history on the shape of the intracluster medium and the TX–M relation [PDF]

Monthly notices of the Royal Astronomical Society, 2019
We use a statistical sample of galaxy clusters from a large cosmological N-body + hydrodynamics simulation to examine the relation between morphology, or shape, of the X-ray emitting intracluster medium (ICM) and the mass accretion history of the ...

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.

Efficient Production of Sound Waves by AGN Jets in the Intracluster Medium [PDF]

Astrophysical Journal, 2019
We investigate the interaction between active galactic nucleus (AGN) jets and the intracluster medium (ICM) of galaxy clusters. Specifically, we study the efficiency with which jets can drive sound waves into the ICM. Previous works focused on this issue

The quiescent intracluster medium in the core of the Perseus cluster [PDF]

Nature, 2016
Clusters of galaxies are the most massive gravitationally bound objects in the Universe and are still forming. They are thus important probes of cosmological parameters and many astrophysical processes. However, knowledge of the dynamics of the pervasive

The Impact of Radio AGN Bubble Composition on the Dynamics and Thermal Balance of the Intracluster Medium [PDF]

Astrophysical Journal, 2018
Feeding and feedback of active galactic nuclei (AGNs) are critical for understanding the dynamics and thermodynamics of the intracluster medium (ICM) within the cores of galaxy clusters.

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.

A Two-Temperature Model of the Intracluster Medium [PDF]

, 1998
We investigate evolution of the intracluster medium (ICM), considering the relaxation process between the ions and electrons. According to the standard scenario of structure formation, ICM is heated by the shock in the accretion flow to the gravitational

Chemical and Thermal History of the Intracluster Medium

, 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.
