Simulating the Arrival of the Southern Substructure in the Galaxy Cluster Abell 1758

The Astrophysical Journal
Abell 1758 ( z ∼ 0.278) is a galaxy cluster composed of two structures, A1758N and A1758S, separated by ∼2.2 Mpc. The northern cluster is itself a dissociative merging cluster that has already been modeled by dedicated simulations.

Gas motion in the intracluster medium of the Virgo cluster replica

Astronomy & Astrophysics
Within the deep gravitational potential of galaxy clusters lies the intracluster medium (ICM). At the first order, it is considered to be at hydrostatic equilibrium within the potential well.

From observations to simulations: A neural-network approach to intracluster medium kinematics

Astronomy & Astrophysics
We present a systematic comparison between XMM-Newton velocity maps of the Virgo, Centaurus, Ophiuchus, and A3266 clusters and synthetic velocity maps generated from the Illustris TNG-300 simulated clusters.

The three-dimensional shapes of the galaxy cluster intracluster medium in eRASS1

Astronomy & Astrophysics
Aims. The three-dimensional shapes of clusters are important for understanding the astrophysics of the clusters and as a probe in cosmological studies. Methods. We estimate the most probable three-dimensional shape of galaxy clusters in the first eROSITA

The Seeding of Cosmic Ray Electrons by Cluster Radio Galaxies: A Review

Galaxies
Radio galaxies in clusters of galaxies are a prominent reservoir of magnetic fields and of non-thermal particles, which become mixed with the intracluster medium.

Investigating the Intracluster Medium Viscosity Using the Tails of GASP Jellyfish Galaxies

The Astrophysical Journal
The microphysics of the intracluster medium (ICM) in galaxy clusters is still poorly understood. Observational evidence suggests that the effective viscosity is suppressed by plasma instabilities that reduce the mean free path of particles. Measuring the

XRISM Reveals Low Nonthermal Pressure in the Core of the Hot, Relaxed Galaxy Cluster A2029

The Astrophysical Journal Letters
We present XRISM Resolve observations of the core of the hot, relaxed galaxy cluster Abell 2029 (A2029). We find that the line-of-sight bulk velocity of the intracluster medium (ICM) within the central 180 kpc is at rest with respect to the brightest ...

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.
