A three-component giant radio halo: the puzzling case of the galaxy cluster Abell 2142
L. Bruno, A. Botteon, T. Shimwell +16
Turbulence introduced into the intra-cluster medium (ICM) through cluster merger events transfers energy to non-thermal components, and can trigger the formation of diffuse synchro…
Exploring the origins of mega radio halos
L. Beduzzi, F. Vazza, G. Brunetti +3
We present a first attempt to investigate the origin of radio-emitting electrons in the newly discovered class of mega radio halos in clusters of galaxies. We study the evolution o…
The Planck clusters in the LOFAR sky V. LoTSS-DR2: Mass - radio halo power correlation at low frequency
V. Cuciti, R. Cassano, M. Sereno +17
Many galaxy clusters show diffuse cluster-scale emission in the form of radio halos, showing that magnetic fields and relativistic electrons are mixed in with the intra-cluster med…
The Planck clusters in the LOFAR sky. II. LoTSS-DR2: Recovering diffuse extended emission with LOFAR
L. Bruno, G. Brunetti, A. Botteon +12
Extended radio sources in the sky require a dense sampling of short baselines to be properly imaged by interferometers. This problem arises in many areas of radio astronomy, such a…
The Planck clusters in the LOFAR sky: IV: LoTSS-DR2: statistics of radio halos and re-acceleration models
R. Cassano, V. Cuciti, G. Brunetti +16
Diffuse cluster-scale synchrotron radio emission is discovered in an increasing number of galaxy clusters in the form of radio halos (RHs), probing the presence of relativistic ele…
The Planck clusters in the LOFAR sky VI. LoTSS-DR2: Properties of radio relics
A. Jones, F. de Gasperin, V. Cuciti +19
Context. It is well-established that shock waves in the intracluster medium launched by galaxy cluster mergers can produce synchrotron emission, which is visible to us at radio fre…
