Constraints on the central engine of merger-driven long gamma-ray bursts
Muskan Yadav, Roberto Ricci, Paz Beniamini +4
Recent observations have identified a new class of long-duration gamma-ray bursts (GRBs) likely produced by compact binary mergers. Using radio observations and lightcurve modellin…
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…
The Advanced X-ray Imaging Satellite (AXIS) Community Science Book
Michael Koss, Nafisa Aftab, Steven W. Allen +395
The AXIS Community Science Book represents the collective effort of 592 scientists worldwide to define the transformative science enabled by the Advanced X-ray Imaging Satellite (A…
AT2025ulz and S250818k: Deep X-ray and radio limits on off-axis afterglow emission and prospects for future discovery
Brendan O'Connor, Roberto Ricci, Eleonora Troja +15
The first joint electromagentic (EM) and gravitational wave (GW) detection, known as GW170817, marked a critical juncture in our collective understanding of compact object mergers.…
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 COLIBRÍ, the Harlingt…
AT2025ulz and S250818k: zooming in with the Hubble Space Telescope
Yu-Han Yang, Eleonora Troja, Marko Ristić +19
AT2025ulz is an optical/near-infrared transient discovered during follow-up of the candidate gravitational wave (GW) event S250818k. Its young age (1 d), rapid decline an…
Exploring the connection between compact object mergers and fast X-ray transients: The cases of LXT 240402A and EP250207b
R. L. Becerra, Yu-Han Yang, Eleonora Troja +29
The connection between compact object mergers and some extragalactic fast X-ray transients (FXRTs) has long been hypothesized, but never ultimately established. In this work, we in…
Radio observations point to a moderately relativistic outflow in the fast X-ray transient EP241021a
Muskan Yadav, Eleonora Troja, Roberto Ricci +7
Fast X-ray transients (FXRTs) are short-lived X-ray outbursts with diverse progenitor scenarios, including compact object mergers, stellar core-collapses and tidal disruption event…
The curious case of EP241021a: Unraveling the mystery of its exceptional rebrightening
Malte Busmann, Brendan O'Connor, Julian Sommer +19
Fast X-ray Transients (FXTs) are a rare and poorly understood phenomenon with a variety of possible progenitors. The launch of the Einstein Probe (EP) mission has facilitated a rap…
Long-term radio monitoring of the fast X-ray transient EP240315a: evidence for a relativistic jet
R. Ricci, E. Troja, Y. Yang +7
The recent launch of Einstein Probe (EP) in early 2024 opened up a new window onto the transient X-ray sky, allowing for real-time discovery and follow-up of fast X-ray transients…
