X-ray Flares in Gamma-Ray Bursts at High and Very-High-Energies
Pawan Tiwari, Biswajit Banerjee, Gor Oganesyan +5
A significant fraction of GRB early afterglows exhibit fast and bright X-ray flares, discovered by Swift X-ray Telescope. Their rapid temporal variability and spectral evolution ha…
Advanced Virgo during the LIGO-Virgo-KAGRA fourth observing run
Virgo Collaboration, F Acernese, A Agapito +546
From April 10, 2024 to November 18, 2025 Advanced Virgo participated in the fourth observing run of the network of gravitational-wave detectors, together with Advanced LIGO and KAG…
The ultra-fast afterglow of GRB 260226A
Biswajit Banerjee, Alessio Mei, Annarita Ierardi +13
Long-duration gamma-ray bursts are typically powered by relativistic jets launched after the core collapse of some rapidly rotating massive stars. Internal dissipation releases par…
Detection of TeV emission during early afterglow from poorly localized GRBs with ground based IACTs
S. Macera, B. Banerjee, M. Seglar-Arroyo +10
Gamma-ray bursts (GRBs) are among the most luminous and rapidly evolving transients in the Universe. While space-based instruments have extended GRB observations up to energies of…
Advanced Virgo Plus for O5 -- Design Report Overview
F. Acernese, A. Agapito, D. Agarwal +578
This document presents an overview of the design, implementation, and expected performance of the Advanced Virgo Plus (AdV+) upgrades in view of the O5 observing run. Following the…
Thermal Electrons in an Ultra-Relativistic Shock Shape the Optical Afterglow of GRB 250702F
Martin Jelínek, Annarita Ierardi, Filip Novotný +8
Observing early optical emission from gamma-ray bursts (GRBs) contemporaneous with the MeV prompt emission phase remains rare, requiring rapid-response robotic facilities. The Ondř…
MeV absorption in gamma-ray bursts as a probe of their progenitor environments
Gor Oganesyan, Om Sharan Salafia, Emanuele Sobacchi +8
A small fraction of X-ray photons from -ray bursts (GRBs), after escaping the relativistic jet, are scattered by electrons in the circumburst medium. Subsequent photon-photon ab…
Early X-ray emission of short Gamma-Ray Bursts: insights into physics and multi-messenger prospects
Annarita Ierardi, Gor Oganesyan, Stefano Ascenzi +3
Early X-ray emission of Gamma-Ray Bursts (GRBs) traces the transition between the prompt emission and the afterglow radiation, and its rapid flux decline is often interpreted as th…
From X-rays to High-Energy Gamma-rays: A Comprehensive Multi-Wavelength Study of Early Gamma-Ray Burst Afterglows
P. Tiwari, B. Banerjee, D. Miceli +8
Gamma-ray Bursts (GRBs) generate powerful relativistic jets that inject a large amount of energy into their surrounding environment, producing blast waves that accelerate particles…
Broadband Modelling of GRB 230812B Afterglow: Implications for VHE -ray Detection with IACTs
Shraddha Mohnani, Biswajit Banerjee, Davide Miceli +13
A significant fraction of the energy from the -ray burst (GRB) jets, after powering the keV-MeV emission, forms an ultra-relativistic shock propagating into the circumburst medi…
Ultra-long MeV transient from a relativistic jet: a tidal disruption event candidate
Gor Oganesyan, Elias Kammoun, Annarita Ierardi +11
On July 2, 2025, the Gamma-ray Burst Monitor (GBM) onboard the Fermi Gamma-ray space telescope detected three short-duration MeV transients with overlapping sky locations. These ev…
