Minutes-duration Optical Flares with Supernova Luminosities
Anna Y. Q. Ho, Daniel A. Perley, Ping Chen +74
In recent years, certain luminous extragalactic optical transients have been observed to last only a few days. Their short observed duration implies a different powering mechanism…
Characterizing the Ordinary Broad-lined Type Ic SN 2023pel from the Energetic GRB 230812B
Gokul P. Srinivasaragavan, Vishwajeet Swain, Brendan M. O'Connor +39
We report observations of the optical counterpart of the long gamma-ray burst (LGRB) GRB 230812B, and its associated supernova (SN) SN 2023pel. The proximity () and high…
Multi-wavelength observations of multiple eruptions of the recurrent nova M31N 2008-12a
Judhajeet Basu, M. Pavana, G. C. Anupama +8
We report the optical, UV, and soft X-ray observations of the eruptions of the recurrent nova M31N 2008-12a. We infer a steady decrease in the accretion rate over the y…
Far-Ultraviolet to Near-Infrared Observations of SN 2023ixf: A high energy explosion engulfed in complex circumstellar material
Rishabh Singh Teja, Avinash Singh, Judhajeet Basu +13
We present early-phase panchromatic photometric and spectroscopic coverage spanning far-ultraviolet (FUV) to the near-infrared (NIR) regime of the nearest hydrogen-rich core-collap…
A Sensitive Search for Supernova Emission Associated with the Extremely Energetic and Nearby GRB 221009A
Gokul P. Srinivasaragavan, Brendan O' Connor, S. Bradley Cenko +24
We report observations of the optical counterpart of the long gamma-ray burst (LGRB) GRB 221009A. Due to the extreme rarity of being both nearby () and highly energetic…
Collapsars as Sites of r-process Nucleosynthesis: Systematic Near-Infrared Follow-up of Type Ic-BL Supernovae
Shreya Anand, Jennifer Barnes, Sheng Yang +41
One of the open questions following the discovery of GW170817 is whether neutron star mergers are the only astrophysical sites capable of producing -process elements. Simulation…
