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…
Evidence for in-situ acceleration of relativistic particles in the wings of X-shaped radio galaxies
Dusmanta Patra, Gopal-Krishna, Ravi Joshi
We report evidence for in-situ acceleration/re-acceleration of relativistic particles in 11 radio wings out of a total of 68 wings sufficiently well-resolved for spectral mapping,…
Low-velocity precessing jets can explain observed morphologies in the Twin Radio Galaxy TRG J104454+354055
Santanu Mondal, Gourab Giri, Ravi Joshi +3
Our understanding of large-scale radio jets in merger systems has been drastically improved in the era of VLA, VLBA/EVN, uGMRT, and MeerKAT. Twin Radio Galaxies (TRGs) are the rare…
A sample of 25 radio galaxies with highly unusual radio morphologies, selected from the LoTSS-DR2 survey at 144 MHz
Gopal-Krishna, Dusmanta Patra, Ravi Joshi
From a careful visual scrutiny of the radio structures of a well-defined sample of 2428 sources in the LoTSS DR2 survey made at 144 MHz with a 6" beam, we have selected a subset of…
