  • 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 2015as: a low-luminosity Type IIb supernova without an early light-curve peak 
    Gangopadhyay, A; Misra, K; Pastorello, A; Sahu, D. K; Tomasella, L; Tartaglia, L; Singh, M; Dastidar, R; Srivastav, S; Ochner, P; Brown, P. J; Anupama, G. C; Benetti, S; Cappellaro, E; Brajesh Kumar; Kumar, B; Pandey, S. B (Oxford University Press on behalf of the Royal Astronomical Society, 2018-05)
    We present results of the photometric (from 3 to 509 days past explosion) and spectroscopic (up to 230 days past explosion) monitoring campaign of the He-rich Type IIb supernova (SN) 2015as. The (B-V) colour evolution of ...
  • SN 2015ba: a Type IIP supernova with a long plateau 
    Dastidar, R; Misra, K; Hosseinzadeh, G; Pastorello, A; Pumo, M. L; Valenti, S; McCully, C; Tomasella, L; Arcavi, I; Elias-Rosa, N; Singh, M; Gangopadhyay, A; Howell, D. A; Morales-Garoffolo, A; Zampieri, L; Kumar, Brijesh; Turatto, M; Benetti, S; Tartaglia, L; Ochner, P; Sahu, D. K; Anupama, G. C; Pandey, S. B (Oxford University Press on behalf of the Royal Astronomical Society, 2018-09)
    We present optical photometry and spectroscopy from about a week after explosion to ∼272 d of an atypical Type IIP supernova, SN 2015ba, which exploded in the edge-on galaxy IC 1029. SN 2015ba is a luminous event with an ...
  • SN 2016B a.k.a. ASASSN-16ab: a transitional Type II supernova 
    Dastidar, R; Misra, K; Singh, M; Sahu, D. K; Pastorello, A; Gangopadhyay, A; Tomasella, L; Benetti, S; Terreran, G; Sanwal, Pankaj; Kumar, B; Singh, A; Brajesh Kumar; Anupama, G. C; Pandey, S. B (Oxford University Press on behalf of the Royal Astronomical Society, 2019-06)
    We present photometry, polarimetry, and spectroscopy of the Type II supernova ASASSN-16ab/SN 2016B in PGC 037392. The photometric and spectroscopic follow-up commenced about 2 weeks after shock breakout and continued until ...
