The role of pressure anisotropy in the turbulent intracluster medium

, 2012
In low-density plasma environments, such as the intracluster medium (ICM), the Larmour frequency is much larger than the ion-ion collision frequency. In such a case, the thermal pressure becomes anisotropic with respect to the magnetic field orientation ...

Merger Shocks Enhance Quenching in Local Galaxy Clusters

The Astrophysical Journal
We report evidence for enhanced quenching in low-redshift galaxy clusters hosting radio relics. This effect is strongest for low-mass galaxies and is consistent with a rapid quenching of star formation.

A Deep Redshift Survey of the Perseus Cluster (A426): Spatial Distribution and Kinematics of Galaxies

The Astrophysical Journal Supplement Series
We study the global kinematics of the Perseus galaxy cluster (A426) at redshift z = 0.017 using a large sample of galaxies from our new MMT/Hectospec spectroscopic observation for this cluster.

Toward Cosmological Simulations of the Magnetized Intracluster Medium with Resolved Coulomb Collision Scale

The Astrophysical Journal
We present the first results of one extremely high-resolution, nonradiative magnetohydrodynamical cosmological zoom-in simulation of a massive cluster with a virial mass of  M _vir = 2.0 × 10 ^15 solar masses. We adopt a mass resolution of 4 × 10 ^5 M _⊙

Metal enrichment of the intracluster medium: SN-driven galactic winds

, 2009
We investigate the role of supernova (SN)-driven galactic winds in the chemical enrichment of the intracluster medium (ICM). Such outflows on galactic scales have their origin in huge star forming regions and expel metal enriched material out of the ...

Suzaku Observations of the Cold Front in A3667: A Nonequilibrium Ionization State of the Intracluster Medium

The Astrophysical Journal
We present a systematic study of the thermodynamic properties of the intracluster medium (ICM), including the plasma conditions in the ICM, in the merging galaxy cluster A3667 using Suzaku. We analyze the X-ray spectra of the ICM between the northwestern
