  • Integral field spectroscopy of the circumnuclear region of the radio galaxy Pictor A 
    Couto, G. S; Storchi-Bergmann, T; Robinson, A; Riffel, R. A; Kharb, P; Lena, D; Schnorr-Muller, A (Oxford University Press on behalf of the Royal Astronomical Society, 2016-06)
    We present optical integral field spectroscopy of the inner 2.5 × 3.4 kpc2 of the broad-line radio galaxy Pictor A, at a spatial resolution of ≈400 pc. Line emission is observed over the whole field of view, being strongest ...
  • Kinematics of two dwarf galaxies in the NGC 6946 group 
    Begum, A; Chengalur, J. N (EDP Sciences, 2004)
    We present high velocity resolution (~ 1.6 km s -1) Giant Meterwave Radio Telescope (GMRT) HI 21 cm synthesis images of the dwarf galaxies KK98 250 and KK98 251, as well as optical broad band images of KK98 250. We find ...
  • A Low-Frequency Study of Recently Identified Double-Double Radio Galaxies 
    Nandi, S; Saikia, D. J; Roy, R; Dabhade, P.; Wadadekar, Y; Larsson, J; Baes, M; Chandola, H. C; Singh, M (Oxford University Press on behalf of the Royal Astronomical Society, 2019-07)
    n order to understand the possible mechanisms of recurrent jet activity in radio galaxies and quasars, which are still unclear, we have identified such sources with a large range of linear sizes (220–917 kpc), and hence ...
  • Mathematical sciences: The dynamics of Colliding Galaxies 
    Namboodiri, P. M. S (2006-01)
    Galaxies interact in a multitude of ways with their environment. Such interactions can alter the morphological type of galaxies, trigger star formation and even produce active galactic nuclei. During the past three decades ...
  • REMAP: Determination of the inner edge of the dust torus in AGN by measuring time delays 
    Mandal, A. K; Rakshit, S; Pal, I; Stalin, C. S; Sagar, R; Mathew, B. (Societe Royale des Sciences de Liege, 2019-10)
    Active galactic nuclei (AGN) are high luminosity sources powered by accretion of matter onto super-massive black holes (SMBHs) located at the centres of galaxies. According to the Unification model of AGN, the SMBH is ...
