Afterglow radiation in gamma-ray bursts (GRB), extending from the radio band to GeV
energies, is produced as a result of the interaction between the relativistic jet and the …

We report the discovery of GRB 221009A, the highest flux gamma-ray burst (GRB) ever
observed by the Fermi Gamma-ray Burst Monitor (Fermi-GBM). This GRB has continuous …

The propagation of gamma-rays over cosmological distances is the subject of extensive
theoretical and observational research at GeV and TeV energies. The mean free path of …

Abstract The ASTRI (Astrofisica con Specchi a Tecnologia Replicante Italiana) Project led by
the Italian National Institute for Astrophysics (INAF) is developing and will deploy at the …

In this paper, we model the dynamics and radiation physics of the rarity event GRB 221009A
afterglow in detail. By introducing a top-hat jet that propagates in an environment dominated …

The current generation of very-high-energy gamma-ray (VHE; E> 30 GeV) detectors (MAGIC
and HESS) have recently demonstrated the ability to detect the afterglow emission of …

Gamma-ray bursts (GRBs) are explosive transient events occurring at cosmological
distances, releasing a large amount of energy as electromagnetic radiation over several …

Context. We are operating an elastic light detecting and ranging system (LIDAR) for the
monitoring of atmospheric conditions during regular observations of the MAGIC telescopes …

Gamma-ray bursts (GRBs) are one of the most exciting sources that offer valuable
opportunities for investigating the evolution of energy fraction given to magnetic fields and …

Gamma-ray bursts (GRBs) are the most luminous explosions in the Universe and are
powered by ultra-relativistic jets. Their prompt γ-ray emission briefly outshines the rest of the …
