  • Evolution of a Peculiar Type Ibn Supernova SN 2019wep 
    Gangopadhyay, A; Misra, Kuntal; Hosseinzadeh, Griffin; Arcavi, Iair; Pellegrino, Craig; Wang, Xiaofeng; Andrew Howell, D; Burke, Jamison; Zhang, Jujia; Kawabata, Koji; Singh, Mridweeka; Dastidar, Raya; Hiramatsu, Daichi; McCully, Curtis; Mo, Jun; Chen, Zhihao; Xiang, Danfeng (American Astronomical Society, 2022-05-10)
    We present a high-cadence short term photometric and spectroscopic monitoring campaign of a type Ibn SN 2019wep, which is one of the rare SN Ibn after SNe 2010al and 2019uo to display signatures of flash ionization (He ii, ...
  • Flash Ionization Signatures in the Type Ibn Supernova SN 2019uo

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 ...
  • Observational Properties of a Bright Type lax SN 2018cni and a Faint Type Iax SN 2020kyg

    We present the optical photometric and spectroscopic analysis of two Type Iax supernovae (SNe), 2018cni and 2020kyg. SN 2018cni is a bright Type Iax SN (MV,peak = −17.81 ± 0.21 mag), whereas SN 2020kyg (MV,peak = −14.52 ± ...
  • Optical studies of a bright Type Iax supernova SN 2020rea 
    Singh, Mridweeka; Misra, Kuntal; Sahu, D. K; Ailawadhi, Bhavya; Dutta, Anirban; Howell, D. Andrew; Anupama, G. C; Bostroem, K. Azalee; Burke, Jamison; Dastidar, Raya; Gangopadhyay, Anjasha; Hiramatsu, Daichi; Im, Hyobin; McCully, Curtis; Pellegrino, Craig; Srivastav, Shubham; Teja, Rishabh Singh (Oxford University Press on behalf of Royal Astronomical Society, 2022-12)
    We present optical photometric and spectroscopic analysis of a Type Iax supernova (SN) 2020rea situated at the brighter luminosity end of Type Iax supernovae (SNe). The light curve decline rate of SN 2020rea is m15(g) = ...
