EP241217a: a likely Type II GRB with an achromatic bump at z = 4.59

Hao Zhou, Jia Ren, Chen-Wei Wang +22

EP241217a is an X-ray transient detected by the Einstein Probe (EP) lasting for about 100 seconds and without accompanying -ray detection. The optical spectroscopy reveals the r…

Optimizing Kilonova Searches: A Case Study of the Type IIb SN 2025ulz in the Localization Volume of the Low-Significance Gravitational Wave Event S250818k

Noah Franz, Bhagya Subrayan, Charles D. Kilpatrick +54

Kilonovae, the ultraviolet/optical/infrared counterparts to binary neutron star mergers, are an exceptionally rare class of transients. Optical follow-up campaigns are plagued by c…

No Sign of a Magnetar Remnant Following the Kilonova-Producing Long GRB 211211A Years Later

Genevieve Schroeder, Ben Margalit, Brian D. Metzger +9

In addition to a -ray burst (GRB), the merger of two neutron stars may produce a temporarily or indefinitely stable neutron star remnant with a strong magnetic field (a "magneta…

Exploring the Relationship Between Swift Short Gamma-Ray Burst Afterglows and their Host Galaxy Properties

Cristian Castrejon, Anya E. Nugent, Wen-fai Fong +3

We present a comprehensive compilation of short-duration gamma-ray burst (GRB) afterglows in the X-ray, optical, and radio bands, comprising 150 events discovered primarily by the…

The kangaroo's first hop: the early fast cooling phase of EP250108a/SN 2025kg

Rob A. J. Eyles-Ferris, Peter G. Jonker, Andrew J. Levan +52

Fast X-ray transients (FXTs) are a rare and poorly understood population of events. Previously difficult to detect in real time, the launch of the Einstein Probe with its wide fiel…
