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'…
