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 $

Effective Viscosity in the Intracluster Medium During Magnetic Field Amplification via Turbulent Dynamo

The Astrophysical Journal
Galaxy clusters, the largest gravitationally bound structures, host a hot, diffuse plasma with poorly understood viscosity and magnetic field amplification.

A Rare, Strong Shock Front in the Merging Cluster SPT-CLJ 2031-4037

The Astrophysical Journal
We present our findings from the new deep Chandra observations (256 ks) of the merging galaxy cluster SPT-CLJ 2031-4037 at z = 0.34. Our observations reveal intricate structures seen in a major merger akin to the Bullet Cluster.

The NuSTAR View of Perseus: The Intracluster Medium and a Peculiar Hard Excess

The Astrophysical Journal
As the brightest galaxy cluster in the X-ray sky, Perseus is an excellent target for studying the intracluster medium (ICM), but until recently, its active galactic nucleus (AGN) made studies of the diffuse emission near its center nearly impossible to ...

Density Fluctuations in the Intracluster Medium: An Attempt to Constrain Viscosity with Cosmological Simulations

The Astrophysical Journal
The impact of viscosity in the intracluster medium (ICM) is still an open question in astrophysics. To address this problem, we have run a set of cosmological simulations of three galaxy clusters with a mass larger than M _Vir > 10 ^15 M _⊙ at z = 0 ...
