EP250827b/SN 2025wkm: An X-ray Flash-Supernova Powered by a Central Engine and Circumstellar Interaction
Gokul P. Srinivasaragavan, Dongyue Li, Xander J. Hall +100
We present the discovery of EP250827b/SN 2025wkm, an X-ray Flash (XRF) discovered by the Einstein Probe (EP), accompanied by a broad-line Type Ic supernova (SN Ic-BL) at $z = 0.119…
An extremely bright slow-rising afterglow from an off-axis jet in GRB 260310A
Yu-Han Yang, Roberto Ricci, Eleonora Troja +31
We present a multi-wavelength study of GRB 260310A, a nearby long-duration gamma-ray burst at associated with a broad-lined Type Ic supernova. Despite its modest pro…
Extremely luminous optical afterglow of an energetic gamma-ray burst GRB 230204B
Rahul Gupta, Judith Racusin, Vladimir Lipunov +47
Robotic telescope networks play an important role in capturing early and bright optical afterglows, providing critical insights into the energetics and emission mechanisms of GRBs.…
Deciphering the Physical Origin of GRB 240825A: A Long GRB Lacking a Bright Supernova
Rahul Gupta, Judith L. Racusin, R. Sanchez-Ramirez +52
We present a comprehensive multiwavelength analysis of GRB 240825A, a bright gamma-ray burst (GRB) detected by Fermi and Swift, with a prompt duration ( ~ 4 sec in 50-3…
