Assessing the Impact of Instrumental Requirements on the Scientific Performance of the Einstein Telescope
Ulyana Dupletsa, Francesco Iacovelli, Mikhail Korobko +23
The paper evaluates how different design choices and noise characteristics of the Einstein Telescope affect its ability to detect and analyze various gravitational‑wave sources, us…
The ultra-fast afterglow of GRB 260226A
Biswajit Banerjee, Alessio Mei, Annarita Ierardi +13
The paper presents Fermi LAT observations of GRB 260226A that captured an unprecedented number of >100 MeV photons, enabling a detailed reconstruction of the early afterglow which…
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…
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 med…
GeV emission from a compact binary merger
Alessio Mei, Biswajit Banerjee, Gor Oganesyan +9
An energetic -ray burst (GRB), GRB 211211A, was observed on 2021 December 11 by the Neil Gehrels Swift Observatory. Despite its long duration, typically associated with bur…
Gamma-ray burst prompt emission spectra at high energies
Samanta Macera, Biswajit Banerjee, Alessio Mei +3
Despite more than fifty years of gamma-ray burst (GRB) observations, several questions regarding the origin of the prompt emission, particularly at high energies, remain unresolved…
