  • The optical properties of three Type II supernovae: 2014cx, 2014cy, and 2015cz 
    Dastidar, R; Misra, K; Singh, M; Pastorello, A; Sahu, D. K; Wang, X; Gangopadhyay, A; Tomasella, L; Zhang, J; Bose, S; Mo, J; Elias-Rosa, N; Tartaglia, L; Yan, S; Brijesh Kumar; Anupama, G. C; Pandey, S. B; Rui, L; Zhang, T; Terreran, G; Ochner, P; Huang, F (Oxford University Press on behalf of the Royal Astronomical Society, 2021-06)
    We present the photometric and spectroscopic analysis of three Type II supernovae (SNe): 2014cx, 2014cy, and 2015cz. SN 2014cx is a conventional Type IIP with shallow slope (0.2 mag/50 d) and an atypical short plateau ...
  • Photometric, polarimetric, and spectroscopic studies of the luminous, slow-decaying Type Ib SN 2012au 
    Pandey, S. B; Amit Kumar; Brajesh Kumar; Anupama, G. C; Srivastav, S; Sahu, D. K; Vinko, J; Aryan, A; Pastorello, A; Benetti, S; Tomasella, L; Singh, A; Moskvitin, A. S; Sokolov, V. V; Gupta, R; Misra, K; Ochner, P; Valenti, S (Oxford University Press on behalf of Royal Astronomical Society, 2021-10)
    Optical, near-infrared (NIR) photometric and spectroscopic studies, along with the optical imaging polarimetric results for SN 2012au, are presented in this article to constrain the nature of the progenitor and other ...
  • 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 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 ...
