eROSITA cosmology with galaxy groups: Hot gas budget out to the virial radius
H. Khalil, A. Finoguenov, D. Eckert +4
Non-gravitational processes that expel hot gas beyond the virial regions of groups and clusters of galaxies, known collectively as baryonic feedback, play a key role in reshaping t…
Large eROSITA X-ray sources as 2MRS galaxy groups
A. Finoguenov, R. Seppi, D. Eckert +5
We aim to exploit the large area coverage, good sensitivity, and low instrumental background of eROSITA to detect the faint surface brightness emission of galaxy groups from the Tw…
Two-component large-scale radio emission in Abell 2244
M. Cianfaglione, F. De Gasperin, V. Cuciti +9
Context. In recent years, clusters have been observed that host multi-component haloes, both in non-merging and merging systems. The existence of these multi-component haloes sugge…

We present MeerKAT observations of the galaxy cluster Abell 2034, a massive (M_500=5.21 10^14 solar masses) nearby cluster in a merging state. Previous observations at 144 MHz have…
The topology of the magnetic field in Abell 2255 out to its virial radius. Results from the LOFAR Galaxy Cluster Ultra-Deep Field
A. Botteon, R. J. van Weeren, Y. Hu +14
We present the LOFAR Galaxy Cluster Ultra-Deep Field, in which 336 h of LOFAR observations at 120168 MHz have been collected on the nearby () cluster Abell 2255. This m…
Radio Halos in Galaxy Clusters as unveiled by the SKA telescope
R. Cassano, G. Di Gennaro, V. Cuciti +24
Giant radio halos (RHs) are diffuse, Mpc-scale synchrotron sources observed in a growing fraction of galaxy clusters. They trace relativistic particles and magnetic fields in the i…
The Treble Clef radio phoenix and its old nonthermal filaments
A. Botteon, M. Brienza, K. Rajpurohit +15
By inspecting data from the LOFAR Two-meter Sky Survey (LoTSS), we noticed a peculiar bright and filamentary radio source at low-galactic latitude (). This source,…
CHEX-MATE: Are we getting cluster thermodynamics right?
R. Seppi, D. Eckert, E. Rasia +19
Galaxy clusters offer powerful insights into the large-scale structure of the Universe and the physics of baryons in hot state. Their scientific exploitation, however, hinges on ou…
XGAP with uGMRT I: Old AGN plasma in merging galaxy groups
R. Santra, R. Kale, K. Kolokythas +10
Galaxy groups are affected by outflows from central Active Galactic Nuclei due to the shallower gravitational potential compared to galaxy clusters. The group binding energy is com…
