A merger shock traced by radio arcs and ultra-long radio tails in galaxy cluster A2142

Chong Ge, Ming Sun, Chris Nolting +2

Abell 2142 (A2142) is a massive, nearby galaxy cluster undergoing a complex merger. It exhibits an elongated X-ray morphology along the northwest-southeast axis and hosts four know…

SLICE -- Combining Strong Lensing and X-ray in AC 114. Further Insights into the Merger Scenario

Marceau Limousin, Benjamin Beauchesne, Keren Sharon +14

AC114 is a historically significant galaxy cluster, being one of the first strong lensing clusters detected from the ground in the early 1990s, prior to the launch of the HST. Desp…

Cross Calibration of Galaxy Cluster Temperatures Measured with NuSTAR, XMM-Newton, and Chandra

Fiona Lopez, Daniel R. Wik, Cicely Potter +10

The use of galaxy clusters to constrain cosmology is limited in part due to uncertainties in derived cluster masses, which often depend on the gas temperature. Unfortunately, there…

CHEX-MATE: Cluster Multi-Probes in Three Dimensions (CLUMP-3D) II. Combined Gas and Dark Matter Analysis from X-ray, SZE, and WL

Adriana Gavidia, Junhan Kim, Jack Sayers +15

Under the standard model of hierarchical structure formation, the overall geometry of galaxy clusters is better described by a triaxial ellipse than a sphere. As a result, applying…

Cross-correlations between X-ray clusters and the general galaxy population

Johan Comparat, Juan Macias-Perez, Céline Combet +5

This study presents highly precise measurements of the cross-correlation between volume-limited galaxy samples from the DESI legacy survey catalogue and X-ray selected galaxy clust…

The Three Hundred Project: Modeling Baryon and Hot-Gas Fraction Evolution in Simulated Clusters

Elena Rasia, Roberta Tripodi, Stefano Borgani +8

The baryon fraction of galaxy clusters is a powerful tool to inform on the cosmological parameters while the hot-gas fraction provides indications on the physics of the intracluste…
