MeerKAT Reveals Evidence of a Radio Megahalo at GHz Frequency

Swarna Chatterjee, Kenda Knowles

Radio megahalos are recently discovered large-scale diffuse synchrotron sources identified through LOFAR observations. We present MeerKAT L-band observations of the massive galaxy…

Radio Halos in Galaxy Clusters as unveiled by the SKA telescope

R. Cassano, G. Di Gennaro, V. Cuciti +24

Giant radio halos (RHs) are diffuse, Mpc-scale synchrotron sources observed in a growing fraction of galaxy clusters. They trace relativistic particles and magnetic fields in the i…

Probing Merger Shocks in Galaxy Clusters in the SKA Era

Arpan Pal, Ruta Kale, Gabriella Di Gennaro +8

Galaxy cluster mergers represent the most energetic phenomena in the Universe since the Big Bang releasing gravitational potential energy of erg, injecting turbul…

Galactic-scale evolution of classical and complex radio galaxies. Impact of ambient morphology and jet geometry

Gourab Giri, Prajnadipt Ghosh, Ravi Joshi +9

Extragalactic jets exhibit a wide range of propagation orientations relative to the host galaxy's principal axis. This study investigate the spatiotemporal evolution of jets as a f…

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…

Illuminating the Diffuse Radio Emission in Low-Mass Cluster: Abell 13

Nasmi S Anand, Swarna Chatterjee, Ramij Raja +2

Recent advances in high-sensitivity radio observations have uncovered a population of faint, ultra-steep-spectrum sources in galaxy clusters, commonly known as radio phoenixes. How…
