The life of central radio galaxies in clusters: AGN-ICM studies of eRASS1 clusters in the ASKAP fields

Angie Veronica, Thomas H. Reiprich, Florian Pacaud +35

The mechanical feedback from the central AGNs can be crucial for balancing the radiative cooling of the intracluster medium at the cluster centre. We aim to understand the relation…

Discovery of Diffuse Radio Emission in a Massive z=1.709 Cool Core Cluster: A Candidate Radio Mini-Halo

Julie Hlavacek-Larrondo, Roland Timmerman, Christoph Pfrommer +10

Clusters of galaxies host spectacular diffuse radio sources, extending over scales from 100 kpc to several Mpcs. These sources, with extremely faint surface brightness (Jy/arcse…

The SRG/eROSITA All-Sky Survey. The Weak-Lensing Mass Calibration and the Stellar Mass-to-Halo Mass Relation from the Hyper Suprime-Cam Subaru Strategic Program

I-Non Chiu, Vittorio Ghirardini, Sebastian Grandis +23

We present the weak-lensing mass calibration and constrain the BCG (brightest cluster galaxy) stellar-mass-to-halo-mass-and-redshift () relation for a s…

The hot circumgalactic medium in the eROSITA All-Sky Survey III. Star-forming and quiescent galaxies

Yi Zhang, Johan Comparat, Gabriele Ponti +17

The circumgalactic medium (CGM), as the gas repository for star formation, might contain the answer to the mysterious galaxy quenching and bimodal galaxy population origin. We meas…

Gas thermodynamics meets galaxy kinematics: Joint mass measurements for eROSITA galaxy clusters

Pengfei Li, Ang Liu, Matthias Kluge +13

The mass of galaxy clusters is a critical quantity for probing cluster cosmology and testing theories of gravity, but its measurement could be biased given assumptions are inevitab…

The warm-hot intergalactic medium in inter-cluster filaments -- A forecast for HUBS observations based on eRASS1 superclusters

Yuanyuan Zhao, Haiguang Xu, Ang Liu +8

Cosmological simulations indicate that nearly half of the baryons in the nearby Universe are in the warm-hot intergalactic medium (WHIM) phase, and about a half them reside in cosm…

The hot circumgalactic medium in the eROSITA All-Sky Survey II. Scaling relations between X-ray luminosity and galaxies' mass

Yi Zhang, Johan Comparat, Gabriele Ponti +16

Understanding how the properties of galaxies relate to the properties of the hot circum-galactic medium (CGM) around them can constrain galaxy evolution models. We measured the X-r…

The hot circumgalactic medium in the eROSITA All-Sky Survey I. X-ray surface brightness profiles

Yi Zhang, Johan Comparat, Gabriele Ponti +17

The circumgalactic medium (CGM) provides the material needed for galaxy formation and influences galaxy evolution. The hot () CGM is poorly detected around galaxies with s…

The SRG/eROSITA All-Sky Survey: View of the Virgo Cluster

Hannah McCall, Thomas H. Reiprich, Angie Veronica +11

As the closest galaxy cluster, the Virgo Cluster is an exemplary environment for the study of the large-scale filamentary structure and physical effects that are present in cluster…

A shock near the virial radius of the Perseus Cluster

Zhenlin Zhu, Aurora Simionescu, Hiroki Akamatsu +6

Previous X-ray studies of the Perseus Cluster, consisting of 85 Suzaku pointings along eight azimuthal directions, revealed a particularly steep decrease in the projected temperatu…
