  • 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 ...
