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…
Host galaxy identification of LOFAR sources in the Euclid Deep Field North
Bisigello L., Giulietti M., Prandoni I. +6
We present a catalogue of optical and near-infrared counterparts to radio sources detected in the Euclid Deep Field North (EDF-N) using observations from the LOw-Frequency ARray (L…
X-ray investigation of the remarkable galaxy group Nest200047
Anwesh Majumder, A. Simionescu, T. Plšek +11
Galaxy groups are more susceptible to feedback from the central active galactic nuclei (AGN) due to their lower gravitational binding energy compared to clusters. This makes them i…
A view of the CIZA J2242.8+5301 galaxy cluster at very low radio frequencies
G. Lusetti, M. Brüggen, H. W. Edler +9
The galaxy cluster CIZA J2242.8+5301 is a well-studied merging galaxy cluster that hosts prominent double radio relics including the famous sausage relic, as well as other diffuse…
Revealing the intricacies of radio galaxies and filaments in the merging galaxy cluster Abell 2255. I. Insights from deep LOFAR-VLBI sub-arcsecond resolution images
E. De Rubeis, M. Bondi, A. Botteon +7
High sensitivity of modern interferometers is revealing a plethora of filaments surrounding radio galaxies, especially in galaxy cluster environments. The morphology and spectral c…
