  • On the observational behaviour of the highly polarized Type IIn supernova SN 2017hcc 
    Brajesh Kumar; Eswaraiah, C; Singh, A; Sahu, D. K; Anupama, G. C; Kawabata, K. S; Yamanaka, Masayuki; Otsubo, Ikki; Pandey, S. B; Nakaoka, Tatsuya; Kawabata, Miho; Aryan, Amar; Akitaya, Hiroshi (Oxford University Press on behalf of the Royal Astronomical Society, 2019-09)
    We present the results based on photometric (Swift UVOT), broad-band polarimetric (V and Rbands) and optical spectroscopic observations of the Type IIn supernova (SN) 2017hcc. Our study is supplemented with spectropolarimetric ...
  • SN 2018gj: A Short Plateau Type II Supernova with Persistent Blueshifted Ha Emission 
    Teja, Rishabh Singh; Singh, Avinash; Sahu, D. K; Anupama, G. C; Kumar, Brajesh; Nakaoka, Tatsuya; Kawabata, Koji S; Yamanaka, Masayuki; Takey, Ali; Kawabata, Miho (American Astronomical Society, 2023-09-10)
    We present an extensive, panchromatic photometric (UV, optical, and near-IR) and low-resolution optical spectroscopic coverage of a Type IIP supernova SN 2018gj that occurred on the outskirts of the host galaxy NGC 6217. ...
  • SN 2018hna: 1987A-like supernova with a signature of shock breakout 
    Singh, A; Sahu, D. K; Anupama, G. C; Brajesh Kumar; Harsh Kumar; Yamanaka, Masayuki; Baklanov, Petr V; Tominaga, Nozomu; Blinnikov, Sergei. I; Maeda, Keiichi; Anirban, D; Bhalerao, Varun; Ramya, M. Anche; Barway, Sudhanshu; Akitaya, Hiroshi; Nakaoka, Tatsuya; Kawabata, Miho; Kawabata, Koji. S; Sasada, Mahito; Takagi, Kengo; Maehara, Hiroyuki; Isogai, Keisuke; Kino, Masaru; Taguchi, Kenta; Nagao, Takashi (IOP Publishing, 2019-09-10)
    High-cadence ultraviolet, optical, and near-infrared photometric and low-resolution spectroscopic observations of the peculiar Type II supernova (SN) 2018hna are presented. The early-phase multiband light curves (LCs) ...
