The plethora of diffuse emission in Abell 2034 as revealed by MeerKAT polarization observations
A. Bonafede, M. Balboni, G. W. Pratt +15
The paper presents MeerKAT multi‑frequency and polarimetric observations of the merging galaxy cluster Abell 2034, confirming a radio halo, identifying a relic and steep‑spectrum f…
MeerKAT observations of Abell 1775 and Abell 1795: the discovery of a hadronic radio halo?
R. J. van Weeren, E. Osinga, G. Brunetti +13
Giant radio haloes are diffuse synchrotron sources typically found in merging galaxy clusters, while smaller mini-haloes occur in cool-core clusters. Both trace cosmic-ray electron…
Revealing the intricacies of radio galaxies and filaments in the merging galaxy cluster Abell 2255. II. Properties of filaments using multi-frequency radio data
E. De Rubeis, M. Bondi, A. Botteon +11
In this paper, we aim to further analyze the filaments in Abell 2255 combining LOFAR data with uGMRT (1260 MHz) and VLA (1520 MHz) data to constrain the spectral shape of the filam…
Resurging from the ashes: A spectral study of seven candidate revived radio fossils in nearby low-mass galaxy clusters
L. Bruno, A. Botteon, D. Dallacasa +17
Complex energy transfer processes in the intracluster medium (ICM) can revive fossil (with spectral ages Myr) plasma initially generated by radio galaxies. This leads to t…
Discovery of large-scale radio emission enveloping the mini-halo in the most X-ray luminous galaxy cluster RX~J1347.5-1145
D. N. Hoang, M. Brüggen, A. Bonafede +8
Diffuse radio sources, known as mini-halos and halos, are detected at the centres of galaxy clusters. These centralized diffuse sources are typically observed individually, with bo…
The evolution of cosmic ray electrons in the cosmic web: seeding by AGN, star formation and shocks
F. Vazza, C. Gheller, F Zanetti +4
Several processes in the Universe convert a fraction of gas kinetic energy into the acceleration of relativistic electrons, making them observable at radio wavelengths, or contribu…
