  • A physically-motivated perspective of Fanaroff–Riley classification of radio galaxies 
    Gopal-Krishna; Wiita, Paul J; Joshi, Ravi; Patra, Dusmanta (Indian Academy of Sciences, 2023-06)
    A small subset of extragalactic double radio sources, termed HYbrid MOrpholgy Radio Sources (HYMORS), is distinguished by a very unusual, hybrid morphology in terms of Fanaroff–Riley (FR) classification. In HYMORS, one ...
  • Spectral index variation across X-shaped radio galaxies 
    Patra, Dusmanta; Joshi, Ravi; Gopal-Krishna (Oxford University Press on behalf of Royal Astronomical Society, 2023-09)
    The formation mechanism of the enigmatic subclass of radio galaxies, called ‘X-shaped radio galaxies’ (XRGs), or ‘winged’ radio galaxies, which account for ∼10 per cent of the radio galaxy population, can be effectively ...
  • The twin radio galaxy TRG J104454+354055 
    Gopal-Krishna; Joshi, Ravi; Patra, Dusmanta; Yang, Xiaolong; Ho, Luis C; Wiita, Paul J; Omar, Amitesh (Oxford University Press on behalf of Royal Astronomical Society, 2022-07)
    We report observations of a bright dumb-bell system of galaxies (z = 0.162) with the upgraded Giant Metrewave Radio Telescope (uGMRT), which show that each member of this gravitationally bound pair of galaxies hosts bipolar ...
