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

On the Origin of the Ancient, Large-scale Cold Front in the Perseus Cluster of Galaxies

The Astrophysical Journal
The intracluster medium of the Perseus Cluster exhibits spiral-shaped X-ray surface brightness discontinuities known as “cold fronts,” which simulations indicate are caused by the sloshing motion of the gas after the passage of a subcluster.

SDSS-C4 3028: the Nearest Blue Galaxy Cluster Devoid of an Intracluster Medium

The Open Journal of Astrophysics
SDSS-C4 3028 is a galaxy cluster at $z=0.061$, notable for its unusually high fraction of star-forming galaxies with 19 star-forming and 11 quiescent spectroscopically-confirmed member galaxies. From Subaru/HSC imaging, we derived a weak lensing mass of $

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 _⊙

XRISM Constrains Atmospheric Motion and Turbulent Dissipation in the Archetypal Radio-mode Feedback System Hydra-A

The Astrophysical Journal
We present XRISM Resolve observations centered on Hydra-A, a redshift z = 0.054 brightest cluster galaxy, which hosts one of the largest and most powerful FR-I radio sources in the nearby Universe.

Gravity-selected galaxy clusters: A tight mass-richness relation and an unclear Compton Y-richness trend

Astronomy & Astrophysics
This paper, the third in a series, investigates the scaling relations between optical richness, weak-lensing mass, and Compton Y for a sample of galaxy clusters selected purely by their gravitational effect on the shapes of background galaxies.
