  • Arp 202: a TDG formed in a parent's extended dark matter halo? 
    Scott, T. C; Lagos, P; Ramya, S; Sengupta, C; Paudel, S; Sahu, D. K; Misra, K; Woo, J. H; Sohn, B .W (Oxford University Press on behalf of the Royal Astronomical Society, 2018-03)
    We report on H α + [N II] imaging of the Arp 202 interacting pair and its tidal dwarf galaxy (TDG) candidate as well as a GMOS long slit spectrum from the TDG candidate, observed with the Gemini North telescope. Our H α + ...
  • Bulge-Disk Evolution in Interacting Bulgeless Galaxies 
    Mousumi Das; Ramya, S; Sengupta, C; Mishra, K (Astronomical Society of the Pacific, 2013-10)
    Bulgeless galaxies are an extreme class of late type spiral galaxies that have practically no bulge and are nearly pure disk in morphology. Their lack of evolution is a puzzle for theories of galaxy formation and the secular ...
  • The extended H i disk and star formation in the dwarf spiral galaxy NGC 4701 
    Mousumi Das; Sengupta, C; Honey, M (IOP Publishing, 2019-02-01)
    We present H i, optical, and near-infrared observations of the nearby bulgeless, dwarf spiral galaxy NGC 4701. The galaxy lies on the Virgo filament and is one of the most gas-rich dwarfs in our local environment. Our aim ...
  • GMRT Neutral Hydrogen Observations of the Sombrero Galaxy 
    Sengupta, C; Balasubramanyam, R; Bekki, K (Astronomical Society of India, 2003)
  • Star formation in bulgeless late type spiral Galaxies 
    Das, M; Ramya, S; Sengupta, C; Mishra, K (Astronomical Society of India, 2012)
    We present radio and follow-up optical observations of a sample of bulgeless late type spiral galaxies. We searched for signs of nuclear activity and disk star formation in the sample galaxies. Interaction induced star ...
  • Star formation in bulgeless late-type galaxies: clues to their evolution 
    Mousumi Das; Sengupta, C; Ramya, S; Misra, K (Wiley-Blackwell, 2012-07)
    We present Giant Meterwave Radio Telescope 1280-MHz radio continuum observations and follow-up optical studies of the disc and nuclear star formation in a sample of low-luminosity bulgeless galaxies. The main aim is to ...
