  • Highlights from the observatories 
    Saikia, D. J (Astronomical Society of India, 2005-03)
  • The Ooty Summer Training Program 1990 
    Saikia, D. J; Salter, C. J; Banhatti, D. G; Ghosh, T; Gothoskar, P; Manoharan, P. K (Astronomical Society of India, 1991)
  • Polarization Asymmetry in CSS Sources 
    Saikia, D. J; Gupta, N (Astronomical Society of India, 2003)
    We show that the compact steep spectrum sources are more asymmetric in the polarization of the outer lobes compared with the more extended ones. This could be due to interaction of the jets with infalling material, which ...
  • Radio Study of a Superwind-galaxy: NGC1482 
    Hota, A; Saikia, D. J (Astronomical Society of India, 2003)
    We present GMRT and VLA observations of the superwind galaxy, NGC1482, which has been discovered to have a remarkable hour-glass shaped optical emission line outflow on both sides of the galactic disk. The central region ...
  • Relativistic beams, thick accretion disks and active galactic nuclei 
    Wiita, P. J; Kapahi, V. K; Saikia, D. J (Astronomical Society of India, 1982-12)
    We review recent analyses of observations of radio galaxies and quasars that support the relativistic beaming models and appear to produce values for the Lorentz factors of the radiating mateiral in the nuclear jets. Thick ...
  • A Study of Giant Radio Galaxies 
    Konar, C; Saikia, D. J; Ishwara-Chandra, C. H; Kulkarni, V. K (Astronomical Society of India, 2003)
    Multi-frequency radio observations have been made of a sample of 17 giant radio galaxies, many of whose structures were not well determined earlier. These sources were observed with the VLA D- and B/C arrays at C and L ...
