Magnetogenesis and the Cosmic Web: a joint challenge for radio observations and numerical simulations
Franco Vazza, Nicola Locatelli, Kamlesh Rajpurohit +16
The detection of the radio signal from filaments in the cosmic web is crucial to distinguish possible magnetogenesis scenarios. We review the status of the different attempts to de…
Direct observation of an extended X-ray jet at =6.1
L. Ighina, A. Moretti, F. Tavecchio +6
We report on the direct observation of an extended X-ray jet in the =6.1 radio-loud Active Galactic Nucleus PSO J030947.49+271757.31 from a deep Chandra X-ray observation (128 k…
Deep low-frequency radio observations of Abell 2256 I: The filamentary radio relic
K. Rajpurohit, R. J. van Weeren, M. Hoeft +22
We present deep and high fidelity images of the merging galaxy cluster Abell 2256 at low frequencies, using the upgraded Giant Metrewave Radio Telescope (uGMRT) and LOw-Frequency A…
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…
VLBI images at 327 MHz of compact steep spectrum and GHz-peaked spectrum sources from the 3C and PW samples
D. Dallacasa, M. Orienti, C. Fanti +1
We present results on global very long baseline interferometry (VLBI) observations at 327 MHz of eighteen compact steep-spectrum (CSS) and GHz-peaked spectrum (GPS) radio sources f…
A MeerKAT view on galaxy clusters: a radio-optical study of Abell 1300 and MACS J1931.8--2634
B. Terni de Gregory, B. Hugo, T. Venturi +8
In this paper we present results from a radio-optical study of the galaxy populations of the galaxy clusters Abell 1300 and MACS J1931.82634, a merger and a relaxed system respe…
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…
Hard X-ray selected giant radio galaxies -- III. The LOFAR view
G. Bruni, M. Brienza, F. Panessa +12
Giant radio galaxies (GRGs), with extended structures reaching hundreds of kpc, are among the most spectacular examples of ejection of relativistic plasma from super-massive black…
Radio multifrequency observations of galaxy clusters. The Abell 399401 pair
C. D. Nunhokee, G. Bernardi, S. Manti +9
Galaxy clusters are assembled via merging of smaller structures, in a process that generates shocks and turbulence in the intra cluster medium and produces radio diffuse emission i…
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…
