    Murai, Yuta; Tanaka, Masaomi; Kawabata, Miho; Taguchi, Kenta; Teja, Rishabh Singh; Nakaoka, Tatsuya; Maeda, Keiichi; Kawabata, Koji S; Nagao, Takashi; Moriya, Takashi J; Sahu, D. K; Anupama, G. C; Tominaga, Nozomu; Morokuma, Tomoki; Imazawa, Ryo; Inutsuka, Satoko; Isogai, Keisuke; Kasuga, Toshihiro; Kobayashi, Naoto; Kondo, Sohei; Maehara, Hiroyuki; Mori, Yuki; Niino, Yuu; Ogawa, Mao; Ohsawa, Ryou; Okumura, Shin-ichiro; Saito, Sei; Sako, Shigeyuki; Takahashi, Hidenori; Uno, Kohki; Yamanaka, Masayuki (Oxford University Press on behalf of Royal Astronomical Society, 2024-03)
    We present photometric, spectroscopic, and polarimetric observations of the intermediate-luminosity Type IIP supernova (SN) 2021gmj from 1 to 386 d after the explosion. The peak absolute V-band magnitude of SN 2021gmj is ...
  • MUSSES2020J: The Earliest Discovery of a Fast Blue Ultraluminous Transient at Redshift 1.063 
    Jiang, Ji-an; Yasuda, Naoki; Maeda, Keiichi; Tominaga, Nozomu; Doi, Mamoru; Ivezic, Zeljko; Yoachim, Peter; Uno, Kohki; Moriya, Takashi J; Kumar, Brajesh; Pan, Yen-Chen; Tanaka, Masayuki; Tanaka, Masaomi; Nomoto, Kenichi; Jha, Saurabh W; Ruiz-Lapuente, Pilar; Jones, David; Shigeyama, Toshikazu; Suzuki, Nao; Kokubo, Mitsuru; Furusawa, Hisanori; Miyazaki, Satoshi; Connolly, Andrew J; Sahu, D. K; Anupama, G. C (IOP Publishing, 2022-07-10)
    In this Letter, we report the discovery of an ultraluminous fast-evolving transient in rest-frame UV wavelengths, MUSSES2020J, soon after its occurrence by using the Hyper Suprime-Cam (HSC) mounted on the 8.2 m Subaru ...
  • Observational Signature of Circumstellar Interaction and 56Ni-mixing in the Type II Supernova 2016gfy 
    Singh, A; Brajesh Kumar; Moriya, Takashi J; Anupama, G. C; Sahu, D. K; Brown, Peter J; Andrews, Jennifer E; Smith, Nathan (IOP Publishing, 2019-09-01)
    The optical and ultraviolet broadband photometric and spectroscopic observations of the Type II supernova (SN) 2016gfy are presented. The V-band light curve (LC) shows a distinct plateau phase with a slope of s2 ∼ 0.12 mag ...
