    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) = ...
  • SN 2020udy: A New Piece of the Homogeneous Bright Group in the Diverse Iax Subclass
