A possible high-redshift origin for the short GRB 061201: implications of a compact binary merger beyond cosmic noon
E. Troja, B. O'Connor, Y. -H. Yang +4
Short gamma-ray bursts (GRBs) at redshift z>2 remain exceptionally rare, yet they are crucial for tracing compact binary mergers in the early Universe and understanding their role…
A merger within a merger: Chandra pinpoints the short GRB 230906A in a peculiar environment
S. Dichiara, E. Troja, B. O'Connor +6
We report the precise X-ray localization of GRB 230906A, a short duration (0.9 s) burst with no optical or radio counterpart. Deep imaging with the Hubble Space Telesco…
Panning for gold with the Neil Gehrels Swift Observatory: an optimal strategy for finding the counterparts to gravitational wave events
R. A. J. Eyles-Ferris, P. A. Evans, A. A. Breeveld +17
The LIGO, Virgo and KAGRA gravitational wave observatories are currently undertaking their O4 observing run offering the opportunity to discover new electromagnetic counterparts to…
Soft X-ray prompt emission from a high-redshift gamma-ray burst EP240315a
Y. Liu, H. Sun, D. Xu +191
Long gamma-ray bursts (GRBs) are believed to originate from core collapse of massive stars. High-redshift GRBs can probe the star formation and reionization history of the early un…
