MeerKAT view of the diffuse radio sources in Abell 3667 and their interactions with the thermal plasma
F. de Gasperin, L. Rudnick, A. Finoguenov +11
During their lifetime, galaxy clusters grow through the accretion of matter from the filaments of the large scale structure and from mergers with other clusters. These mergers rele…
A LOFAR-uGMRT spectral index study of distant radio halos
G. Di Gennaro, R. J. van Weeren, R. Cassano +9
Context. Radio halos are megaparsec-scale diffuse radio sources{ mostly} located at the centres of merging galaxy clusters. The common mechanism invoked to explain their origin is…
Discovery of a radio halo (and relic) in a M cluster
A. Botteon, R. Cassano, R. J. van Weeren +12
Radio halos are diffuse synchrotron sources observed in dynamically unrelaxed galaxy clusters. Current observations and models suggest that halos trace turbulent regions in the int…
Radio relics in PSZ2 G096.88+24.18: A connection with pre-existing plasma
A. Jones, F. de Gasperin, V. Cuciti +10
Giant radio relics are arc-like structures of diffuse, non-thermal synchrotron radiation that trace shock waves induced by galaxy cluster mergers. The particle (re-)acceleration me…
The LOFAR and JVLA view of the distant steep spectrum radio halo in MACS J1149.5+2223
L. Bruno, K. Rajpurohit, G. Brunetti +11
Radio halos and relics are Mpc-scale diffuse radio sources in galaxy clusters, with a steep spectral index (). It has been proposed that they arise from part…
Nonthermal phenomena in the center of Abell 1775: An 800 kpc head-tail, revived fossil plasma and slingshot radio halo
A. Botteon, S. Giacintucci, F. Gastaldello +15
Thermal gas in the center of galaxy clusters can show substantial motions that generate surface-brightness and temperature discontinuities known as cold fronts. The motions may be…
The LOFAR LBA Sky Survey I. survey description and preliminary data release
F. de Gasperin, W. L. Williams, P. Best +38
LOFAR is the only radio telescope that is presently capable of high-sensitivity, high-resolution (<1 mJy/b and <15") observations at ultra-low frequencies (<100 MHz). To utilise th…
Radio halos in a mass-selected sample of 75 galaxy clusters. II. Statistical analysis
V. Cuciti, R. Cassano, G. Brunetti +8
Many galaxy clusters host Mpc scale diffuse radio sources called radio halos. Their origin is connected to the processes that lead to the formation of clusters themselves. In order…
Radio halos in a mass-selected sample of 75 galaxy clusters. I. Sample selection and data analysis
V. Cuciti, R. Cassano, G. Brunetti +9
Radio halos are synchrotron diffuse sources at the centre of a fraction of galaxy clusters. The study of large samples of clusters with adequate radio and X-ray data is necessary t…
