    We report observations of the optical counterpart of the long gamma-ray burst (GRB) GRB 230812B and its associated supernova (SN) SN 2023pel. The proximity (z = 0.36) and high energy (Eγ,iso ∼ 1053 erg) make it an important ...
  • A Sensitive Search for Supernova Emission Associated with the Extremely Energetic and Nearby GRB 221009A 
    Srinivasaragavan, Gokul P; O'Connor, Brendan; Bradley Cenko, S; Dittmann, Alexander J; Yang, Sheng; Sollerman, Jesper; Anupama, G. C; Barway, Sudhanshu; Bhalerao, Varun; Kumar, Harsh; Swain, Vishwajeet; Hammerstein, Erica; Holt, Isiah; Anand, Shreya; Andreoni, Igor; Coughlin, Michael W; Dichiara, Simone; Gal-Yam, Avishay; Coleman Miller, M; Soon, Jaime; Soria, Roberto; Durbak, Joseph; Gillanders, James H; Laha, Sibasish; Moore, Anna M; Ragosta, Fabio; Troja, Eleonora (American Astronomical Society, 2023-06-01)
    We report observations of the optical counterpart of the long gamma-ray burst GRB 221009A. Due to the extreme rarity of being both nearby (z = 0.151) and highly energetic (Eγ,iso 1054 erg), GRB 221009A offers a unique ...

K; Singh, A; Sollerman, Jesper; Stanway, E; Starling, R; Steeghs, D; Teja, Rishabh Singh; Ulaczyk, K (Oxford University Press on behalf of Royal Astronomical Society, 2025-02)
    SN 2023tsz is a Type Ibn supernova (SN Ibn), an uncommon subtype of stripped-envelope core-collapse supernovae (SNe), discovered in an extremely low-mass host. SNe Ibn are characterized by narrow helium emission lines in ...
