Very High-Energy GRB Afterglow Fits with Neural-Network Emulation and Bayesian inference
Edilberto Aguilar-Ruiz, Jessica Saldívar Talavera, Ramandeep Gill +1
The very high-energy ( GeV) afterglow emission in gamma-ray bursts (GRBs) can be explained by synchrotron self-Compton (SSC). Modeling this emission accurately requires fu…
EP260119a: A High-Redshift Gamma-Ray Quiet Fast X-ray Transient Probing a Potentially Hidden Population of Relativistic Explosions
Camila Angulo-Valdez, Asuka Kuwata, Edilberto Aguilar-Ruiz +41
Gamma-ray quiet fast X-ray transients (FXTs) provide a new approach for studying relativistic explosions that evade traditional gamma-ray triggers. In this work, we present multi-w…
Revealing the Structure and Magnetization of GRB Jets with ALMA Polarization Observations
Tanmoy Laskar, Collin T. Christy, Noah Franz +9
We present a systematic study of the currently available ALMA millimeter polarimetric sample of gamma-ray burst (GRB) afterglows. Our sample comprises 24 observations (20 new) of 1…
Early Optical Follow-up of Gamma-Ray Bursts: The Critical Role of Robotic Telescopes
Rahul Gupta, Judith Racusin, Gor Oganesyan +26
Gamma-ray bursts (GRBs) are the most luminous electromagnetic explosions in the Universe, and offer unique laboratories for studying relativistic jets, compact-object formation, pa…
Failed jet breakout in the metal-poor broad-lined type Ic supernova 2026gzf
Antonio Martin-Carrillo, Christina C. Thöne, James K. Leung +103
A long-standing question in the death of massive stars is the role of relativistic jets. While many gamma-ray bursts and some fast X-ray transients seem to be associated with broad…
Earliest simultaneous multi-color optical observations of GRB 230328B: from 41 seconds to the host-galaxy identification
T. Komesh, A. Pozanenko, N. Pankov +36
We present a multiwavelength study of the long-duration gamma-ray burst GRB 230328B, combining prompt gamma-ray observations with exceptionally early simultaneous optical photometr…
GRB 260310A / SN 2026fgk: A Multi-Wavelength Study of a Nearby Underluminous Long GRB and SN with a Complex Afterglow
Ramandeep Gill, Rosa L. Becerra, Antonio de Ugarte Postigo +54
We present a comprehensive multi-wavelength study of GRB 260310A / SN 2026fgk, a nearby (), long-duration gamma-ray burst (GRB) with an exceptionally underluminous prompt…
First Detection of Faraday Rotation in a Gamma-Ray Burst Afterglow: Low Polarization and High Rotation Measure in GRB 260310A Reveal Jet Magnetic Structure and Environment
Collin T. Christy, Tanmoy Laskar, Kate D. Alexander +10
We report the detection of linear polarization in the radio afterglow of GRB 260310A, representing the first centimeter-wavelength polarization detection of a gamma-ray burst (GRB)…
Multi-epoch afterglow rebrightenings in GRB 250129A: Evidence for successive shock interactions
D. Akl, S. Antier, H. Koehn +105
Most long gamma-ray bursts (GRBs) exhibit afterglows broadly consistent with external forward-shock emission, typically described by smooth broken power-law decays in the multiband…
Prospects of Prompt Gamma-Ray Burst Polarimetry with POLAR-2
Ramandeep Gill, Jiang He, Jonathan Granot +6
The dominant radiation mechanism that powers the prompt -ray emission in gamma-ray bursts (GRBs) remains poorly understood. High quality, time- and energy-resolved linear polari…
