  • Radio observations of a nearby type IIP SN 2012aw 
    Yadav, N; Ray, A; Chakraborti, S; Stockdale, C; Chandra, P; Smith, R; Roy, R; Dwarkadas, V; Sutaria, F. K; Pooley, D; Kumar, B; Bose, S (Cambridge University Press, 2014-01)
    SN 2012AW is a type-IIP supernova which exploded in M95. In this paper we discuss the radio observations of this supernova and model them to determine the important parameters relevant to the explosion and the evolution ...
  • SN 2012aa: a transient between type Ibc core-collapse and superluminous supernovae 
    Roy, R; Sollerman, J; Silverman, J. M; Pastorello, A; Fransson, C; Drake, A; Taddia, F; Fremling, C; Kankare, E; Brajesh Kumar; Cappellaro, E; Bose, S; Benetti, S; Filippenko, A. V; Valenti, S; Nyholm, A; Ergon, M; Sutaria, F. K; Kumar, B; Pandey, S. B; Nicholl, M; Garcia-Alvarez, D; Tomasella, L; Karamehmetoglu, E; Migotto, K (EDP Sciences, 2016-12)
    Context. Research on supernovae (SNe) over the past decade has confirmed that there is a distinct class of events which are much more luminous (by ~2 mag) than canonical core-collapse SNe (CCSNe). These events with visual ...
  • SN 2013ab: a normal type IIP supernova in NGC 5669 
    Bose, S; Valenti, S; Misra, K; Pumo, M. L; Zampieri, L; Sand, D; Kumar, B; Pastorello, A; Sutaria, F. K; Maccarone, T. J; Kumar, B; Graham, M. L; Howell, D. A; Ochner, P; Chandola, H. C; Pandey, S. B (Oxford University Press on behalf of the Royal Astronomical Society, 2015-07-01)
    We present densely sampled ultraviolet/optical photometric and low-resolution optical spectroscopic observations of the Type IIP supernova 2013ab in the nearby (∼24 Mpc) galaxy NGC 5669, from 2 to 190 d after explosion. ...
  • SN 2013ej: a type IIL supernova with weak signs of interaction 
    Bose, S; Sutaria, F. K; Kumar, B; Duggal, C; Misra, K; Brown, P. J; Singh, M; Dwarkadas, V; York, D. G; Chakraborti, S; Chandola, H. C; Dahlstrom, J; Ray, A; Safonova, M (IOP Publishing, 2015-06)
    We present optical photometric and spectroscopic observations of SN 2013ej. It is one of the brightest Type II supernovae (SNe II) exploded in a nearby (∼10 Mpc) galaxy, NGC 628. The light-curve characteristics are similar ...
