SKAVLBI view of AGN jets in the early Universe
C. Spingola, M. Mezcua, Y. Liu +33
Active Galactic Nuclei (AGN) are among the brightest sources in the Universe, and those that are also jetted are uniquely valuable at the earliest epochs, because their relativisti…
The SKA View of Cool-core Clusters: Evolution of Radio Mini-halos and AGN Feedback
Myriam Gitti, Paolo Tozzi, Francesco Ubertosi +12
In about 70 per cent of relaxed, cool-core galaxy clusters, the brightest cluster galaxy (BCG) is radio loud, showing non-thermal radio jets and lobes ejected by the central active…
The LOFAR Two-metre Sky Survey: VII. Third Data Release
T. W. Shimwell, M. J. Hardcastle, C. Tasse +99
We present the third data release of the LOFAR Two-metre Sky Survey (LoTSS-DR3). The survey images cover 88% of the northern sky and were created from 12,950 hrs of data (18.6 PB)…
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…
Combined LOFAR-uGMRT analysis of the diffuse radio emission in the massive clusters Abell 773 and Abell 1351
K. S. L. Srikanth, A. Botteon, R. Cassano +20
Radio halos are megaparsec-scale diffuse, non-thermal radio sources located at the centers of galaxy clusters, tracing relativistic particles and magnetic fields in the intra-clust…
Milliarcsecond-resolution Radio-imaging Survey of Blazar Candidates at 4 < z < 5.4
Máté Krezinger, Alessandro Caccianiga, Daniele Dallacasa +9
We present a milliarcsecond-resolution radio survey of 17 high-redshift (4 < z < 5.4) blazar candidates observed with the European Very Long Baseline Interferometry (VLBI) Network…
