  • Giant Low Surface Brightness Galaxies 
    Mishra, A; Kantharia, N. G; Mousumi Das; Nimisha, G (Bulletin de la Societe Royale des Sciences de Liege, 2018-04)
    In this paper, we present radio observations of the giant low surface brightness (LSB) galaxies made using the Giant Metrewave Radio Telescope (GMRT). LSB galaxies are generally large, dark matter dominated spirals that ...
  • GMRT H I study of giant low surface brightness galaxies 
    Mishra, A; Kantharia, N. G; Das, Mousumi; Omar, A; Srivastava, D. C (Oxford University Press on behalf of the Royal Astronomical Society, 2017-01)
    We present H I observations of four giant low surface brightness (GLSB) galaxies UGC 1378, UGC 1922, UGC 4422 and UM 163 using the Giant Meterwave Radio Telescope. We include H I results on UGC 2936, UGC 6614 and Malin 2 ...
  • GMRT Observations of the 2006 outburst of the Nova RS Ophiuchi: First detection of emission at radio frequencies < 1.4 GHz 
    Kantharia, N. G; Anupama, G. C; Prabhu, T. P; Ramya, S; Bode, M. F; Eyres, S. P. S; O'Brien, T. J (University of Chicago Press, 2007-10)
    The first low radio frequency (<1.4 GHz) detection of the outburst of the recurrent nova RS Ophiuchi is presented in this Letter. Radio emission was detected at 0.61 GHz on day 20 with a flux density of 48 mJy and at 0.325 ...
  • An H I shell-like structure associated with nova V458 Vulpeculae? 
    Nirupam Roy; Kantharia, N. G; Eyres, S. P. S; Anupama, G. C; Bode, M. F; Prabhu, T. P; O'Brien, T. J (Wiley-Blackwell, 2012-11)
    We report the radio detection of a shell-like H i structure in proximity to, and probably associated with, the nova V458 Vul. High spectral resolution observation with the Giant Metrewave Radio Telescope has made it possible ...
  • Insights into the evolution of symbiotic recurrent novae from radio synchrotron emission: V745 Scorpii and RS Ophiuchi 
    Kantharia, N. G; Dutta, P; Roy, N; Anupama, G. C; Ishwara-Chandra, C. H; Chitale, A; Prabhu, T. P; Banerjee, D. P. K; Ashok, N. M (Oxford University Press on behalf of the Royal Astronomical Society, 2016-02)
    We present observations at 610 and 235 MHz using the Giant Metrewave Radio Telescope (GMRT) of the recurrent nova V745 Scorpii which recorded its last outburst on 2014 February 6. This is the second symbiotic recurrent ...
  • Late time X-ray, IR and radio observations of the tidal disruption event galaxy NGC 5905 
    Raichur, H; Mousumi Das; Herrero, A. A; Shastri, P; Kantharia, N. G (Springer, 2015-04)
    NGC 5905 is one of the few galaxies with no prior evidence for an active galactic nucleus (AGN) in which an X-ray flare was detected by the ROSAT All Sky Survey (RASS) in 1990–1991. Follow-up studies showed that the X-ray ...
  • Modelling the synchrotron light curves in recurrent novae V745 Scorpii and RS Ophiuchi 
    Kantharia, N. G; Dutta, P; Roy, N; Anupama, G. C; Chitale, A; Ishwara-Chandra, C; Prabhu, T. P; Ashok, N. M; Banerjee, D. P. K (Astronomical Society of India, 2015-02)
    In this paper, we present the synchrotron light curve at 610 MHz from the recurrent nova V745 Sco following its outburst on 6 February 2014. The system has been detected and periodically monitored with the Giant Metrewave ...
  • A multiwavelength study of the remnant of nova GK Persei 
    Anupama, G. C; Kantharia, N. G (EDP Sciences, 2005-09)
    We present new observations of the nebular remnant of the old nova GK Persei 1901 in the optical using the Himalayan Chandra Telescope (HCT) and at low radio frequencies using the Giant Metrewave Radio Telescope (GMRT). ...
  • Radio Continuum and H I Study of Blue Compact Dwarf Galaxies 
    Ramya, S; Kantharia, N. G; Prabhu, T. P (IOP Publishing, 2011-02)
    The multifrequency radio continuum and 21 cm H I observations of five blue compact dwarf (BCD) galaxies, Mrk 104, Mrk 108, Mrk 1039, Mrk 1069, and I Zw 97, using the Giant Meterwave Radio Telescope (GMRT) are presented ...
  • A radio continuum and H I study of optically selected blue compact dwarf galaxies: Mrk 1039 and Mrk 0104 
    Ramya, S; Kantharia, N. G; Prabhu, T. P (Astronomical Society of the Pacific, 2009-09)
    We present a GMRT radio continuum and H I study of two Blue Compact Dwarf (BCD) galaxies Mrk 1039 and Mrk 0104. GMRT 610 MHz observations of Mrk 1039 show that the emission is coincident with a bright intense star forming ...
  • RS Ophiuchi 
    Anupama, G. C; Kantharia, N. G (Central Bureau for Astronomical Telegrams, 2006-03)
  • RS Ophiuchi: radio lightcurve development following the 2006 outburst 
    Eyres, S. P. S; Rushton, M; O'Brien, T. J; Beswick, R; Muxlow, T. W. B; Davis, R; Anupama, G. C; Kantharia, N. G; Bode, M; Gawroñski, M. P; Feiler, R; Evans, A (Astronomical Society of a Pacific, 2009-01)
    We report GHz observations beginning 4.5 days after the discovery of RS Ophiuchi undergoing its 2006 recurrent nova outburst. Observations over the first 60 days are included, enabling us to follow spectral development ...
  • Studying the radio continuum from nuclear activity and star formation in giant low surface brightness galaxies
