  • Circumstellar Interaction Powers the Light Curves of Luminous Rapidly Evolving Optical Transients 
    Pellegrino, C.,et.al.; Misra, K. (The Astrophysical Journal, 2022-02)
    Rapidly evolving transients, or objects that rise and fade in brightness on timescales two to three times shorter than those of typical Type Ia or Type II supernovae (SNe), have uncertain progenitor systems and ...
  • Evolution of a Peculiar Type Ibn Supernova SN 2019wep 
    Gangopadhyay, Anjasha; Misra, Kuntal, et.al. (Astrophysical Journal, 2022-05)
    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 ...
  • Far-ultraviolet to Near-infrared Observations of SN 2023ixf: A High-energy Explosion Engulfed in Complex Circumstellar Material 
    Teja, Rishabh Singh; Singh, Avinash; Basu, Judhajeet; Anupama, G. C.; Sahu, D. K.; Dutta, Anirban; Swain, Vishwajeet; Nakaoka, Tatsuya; Pathak, Utkarsh; Bhalerao, Varun; Barway, Sudhanshu; Kumar, Harsh; A. J, Nayana; Imazawa, Ryo; Kumar, Brajesh; Kawabata, Koji S. (Astrophysical Journal Letters, 2023-09)
    We present early-phase panchromatic photometric and spectroscopic coverage spanning the far-ultraviolet to near infrared regime of the nearest hydrogen-rich core-collapse supernova (SN) in the last 25 yr, SN 2023ixf. ...
  • Investigating the Observational Properties of Type Ib Supernova SN 2017iro 
    Kumar, Brajesh; Singh, Avinash; Sahu, D. K.; Anupama, G. C. (The Astrophysical Journal, 2022-03)
    We report results of optical imaging and low-resolution spectroscopic monitoring of supernova (SN) 2017iro that occurred in the nearby (∼31 Mpc) galaxy NGC 5480. The He I λ5876 feature present in the earliest spectrum (−7 ...
  • SN 2020jfo: A Short-plateau Type II Supernova from a Low-mass Progenitor 
    Teja, Rishabh Singh,et.al.; Kumar, Brajesh (The Astrophysical Journal, 2022-05)
    We present spectroscopic and photometric observations of the Type IIP supernova, SN 2020jfo, in ultraviolet and optical wavelengths. SN 2020jfo occurred in the spiral galaxy M61 (NGC 4303), with eight observed supernovae ...
