LOFAR high-band antenna observations of the Perseus cluster
R. J. van Weeren, R. Timmerman, V. Vaidya +13
The Perseus cluster is the brightest X-ray cluster in the sky and is known as a cool-core galaxy cluster. Being a very nearby cluster, it has been extensively studied. This has pro…
Ultra-low frequency LOFAR spectral indices of cluster radio halos
T. Pasini, F. de Gasperin, M. Brüggen +11
A fraction of galaxy clusters harbor diffuse radio sources known as radio halos. The currently adopted scenario for their formation is based on second-order Fermi re-acceleration o…
Cosmological simulations of the generation of cluster-scale radio emission from turbulent re-acceleration
Luca Beduzzi, Franco Vazza, Virginia Cuciti +3
Context. The recent discovery of so-called mega radio halos as a new class of diffuse, steep-spectrum radio sources in clusters of galaxies has raised questions about the origin an…
Probing particle acceleration in Abell 2256: from to 16 MHz to gamma rays
E. Osinga, R. J. van Weeren, G. Brunetti +9
Merging galaxy clusters often host spectacular diffuse radio synchrotron sources. These sources can be explained by a non-thermal pool of relativistic electrons accelerated by shoc…
Re-energisation of AGN head-tail radio galaxies in the galaxy cluster ZwCl0634.1+47474
G. Lusetti, F. de Gasperin, V. Cuciti +10
Low-frequency radio observations show an increasing number of radio galaxies located in galaxy clusters that display peculiar morphologies and spectral profiles. This is the result…
