EP250108a/SN 2025kg: A Jet-Driven Stellar Explosion Interacting With Circumstellar Material
Gokul P. Srinivasaragavan, Hamid Hamidani, Genevieve Schroeder +28
We present optical, radio, and X-ray observations of EP250108a/SN 2025kg, a broad-line Type Ic supernova (SN Ic-BL) accompanying an Einstein Probe (EP) fast X-ray transient (FXT) a…
EP240414a: A Gamma-Ray Burst Jet Weakened by an Extended Circumstellar Material
Hamid Hamidani, Yuri Sato, Kazumi Kashiyama +3
The recent Einstein Probe (EP) event EP240414a exhibits several unusual observational features. Its prompt and afterglow emissions place it between long gamma-ray bursts (LGRBs) an…
Gamma-Ray Burst Jets in Circumstellar Material: Dynamics, Breakout, and Diversity of Transients
Hamid Hamidani, Kunihito Ioka, Kazumi Kashiyama +1
Recent observations indicate that stripped-envelope core-collapse supernovae are often surrounded by dense circumstellar material (CSM). Motivated by this, we develop an analytic m…
Prompt Periodicity in the GRB 211211A Precursor: Black-hole or magnetar engine?
Gavin P. Lamb, Thomas Baxter, Conor M. B. Omand +18
The merger origin long GRB 211211A was a class (re-)defining event. A precursor was identified with a s separation from the main burst, as well as a claimed candidate quas…
