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…
Broadband Modelling of GRB 230812B Afterglow: Implications for VHE -ray Detection with IACTs
Shraddha Mohnani, Biswajit Banerjee, Davide Miceli +13
A significant fraction of the energy from the -ray burst (GRB) jets, after powering the keV-MeV emission, forms an ultra-relativistic shock propagating into the circumburst medi…
Deciphering the spectral properties of the atypical radio relic in A115 using uGMRT, VLA, and LOFAR
Swarna Chatterjee, Abhirup Datta
The mega-parsec scale radio relics at the galaxy cluster periphery are intriguing structures. While textbook examples of relics posit arc-like elongated structures at the clusters'…
Exploring the Dynamical Nature and Radio Halo Emission of Abell 384: A Combined Radio, X-ray and Optical Study
Swarna Chatterjee, Denisha Pillay, Abhirup Datta +4
Multiwavelength studies of galaxy clusters are crucial for understanding the complex interconnection of the thermal and non-thermal constituents of these massive structures and unc…
A new enigmatic radio relic in the low mass cluster Abell 2108
Swarna Chatterjee, Majidul Rahaman, Abhirup Datta +2
We report the discovery of a radio relic in the northeastern periphery of the cluster Abell 2108 (A2108). A2108 is a part of the uGMRT LOw-MAss Galaxy Cluster Survey (GLOMACS), whe…
