JWST observations of SN 2024abup: First Detection of CO in a broad-lined Type Ic Supernova and Constraints on r-process Nucleosynthesis

Manisha Shrestha, Lindsey A. Kwok, David J. Sand +42

SN 2024abup is a nearby broad-lined Type Ic supernova (SN Ic-bl) in NGC 0681 at a distance of 23.3 \pm 1.6 Mpc. As energetic explosions of massive stars, SNe Ic-bl are considered a…

EP251023a: A fast X-ray transient featuring a magnetar-powered optical internal plateau followed by a steep decay

Shuai-Qing Jiang, Dong Xu, Wei-Hua Lei +33

EP251023a is an extragalactic fast X-ray transient (eFXT) detected solely by EP without a gamma-ray counterpart. The prompt emission consists of a main emission with a duration $T_…
