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…
GRB 260310A/SN 2026fgk: Photometric and Spectroscopic Evolution of a Nearby GRB-Supernova and an Exceptionally Bright Afterglow at z=0.153
Brendan O'Connor, Malte Busmann, Xander J. Hall +24
The association of broad-lined Type Ic supernovae with long-duration gamma-ray bursts (GRBs) has been known for 28 years. However, only about seventy gamma-ray burst supernovae (GR…
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…
The Very Late Time Afterglow of GW170817 Favors a Wobbling Jet
Hao Wang, Ore Gottlieb, Aman Katira +4
GW170817 remains the only binary neutron star merger detected through multimessenger emission. Its afterglow has been monitored for nearly a decade, offering an unprecedented oppor…
Evidence of Energy Injection in the Short and Distant GRB 250221A in a High Density Environment
Camila Angulo-Valdez, Rosa L. Becerra, Ramandeep Gill +29
We present the photometric and spectroscopic analysis of the short-duration GRB 250221A ( s), using a data set from the optical facilities COLIBRÃ, the Harling…
