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,…
Origin of the double-peaked narrow emission-lines in the optical spectra of X-shaped Radio Galaxies
Ghosh Prajnadipt, Ravi Joshi, Xiaolong Yang +13
We investigate X-shaped radio galaxies (XRGs) with optical double-peaked narrow emission lines (DPNELs) as potential hosts of dual or binary supermassive black holes (SMBHs). Using…
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…
Spectral index variation across X-shaped radio galaxies
Dusmanta Patra, Ravi Joshi, Gopal-Krishna
The formation mechanism of the enigmatic subclass of radio galaxies, called 'X-shaped radio galaxies' (XRGs), or 'winged' radio galaxies, which account for of the radio…
A physically-motivated perspective of the Fanaroff-Riley classification of radio galaxies
Gopal-Krishna, Paul J. Wiita, Ravi Joshi +1
A small subset of extragalactic double radio sources, termed HYMORS (HYbrid MOrpholgy Radio Sources), is distinguished by a very unusual, hybrid morphology in terms of the Fanaroff…
The Twin Radio galaxy TRG J104454+354055
Gopal-Krishna, Ravi Joshi, Dusmanta Patra +4
We report observations of a bright dumb-bell system of galaxies () with the upgraded Giant Metrewave Radio Telescope (GMRT), which show that each member of this gravit…
Multi-frequency study of large size radio galaxies 3C 35 and 3C 284
Dusmanta Patra, Sabyasachi Pal
We report multi-frequency observations of large radio galaxies 3C 35 and 3C 284. The low-frequency observations were done with Giant Metrewave Radio Telescope starting from $\sim15…
