C; Williams, G. G; Wyatt, S; Zhang, J; Zhang, X (IOP Publishing, 2020-05-20)
    We present the discovery and high-cadence follow-up observations of SN 2018ivc, an unusual SNe II that exploded in NGC 1068 (D = 10.1 Mpc). The light curve of SN 2018ivc declines piecewise-linearly, changing slope ...

K; Pankaj Sanwal; Singh, A; Singh, M; Zhang, Jicheng; Zhang, Tianmeng; Zhang, Xinhan (IOP Publishing, 2020-02-01)
    We present photometric and spectroscopic observations of the type Ibn supernova (SN) 2019uo, the second ever SN Ibn with flash ionization (He ii, C iii, N iii) features in its early spectra. SN 2019uo displays a rapid ...
  • 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.

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 ...
