Comparing the size evolution of GRB 221009A with afterglow models
S. Giarratana, O. S. Salafia, B. Marcote +10
We present very long baseline interferometry (VLBI) observations of GRB221009A obtained with the global-VLBI network at 5 GHz between 231 and 750 days after the burst. The quality…
Colour evolution in the radio afterglow of GRB 241025A
S. Giarratana, O. S. Salafia, L. Nava +10
We present the observing campaign of the afterglow of GRB241025A, a gamma-ray burst (GRB) whose prompt emission has been simultaneously detected by Swift, Einstein Probe, Fermi/GBM…
Late-time X-ray afterglows of GRBs: Implications for particle acceleration at relativistic shocks
Zhi-Qiu Huang, Om Sharan Salafia, Lara Nava +2
Particle-in-cell (PIC) numerical simulations are currently among the most advanced tools to investigate particle acceleration at relativistic shocks. Still, they come with limitati…
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…
A self-consistent explanation of the MeV line in GRB 221009A unveils a dense circum-stellar medium
O. S. Salafia, A. Celotti, E. Sobacchi +6
GRB~221009A has been the brightest gamma-ray burst (GRB) observed to date, and its afterglow has been characterized with unprecedented detail at TeV energies by LHAASO. Quite puzzl…
The very high energy view of gamma-ray bursts with the MAGIC telescopes
Alessio Berti, Željka Bošnjak, Alberto Castro-Tirado +22
Gamma-ray bursts (GRBs) are one of the main targets for the observations of the MAGIC telescopes. As a result of the effort in improving the sensitivity of the instrument and the a…
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…
The Science of the Einstein Telescope
Adrian Abac, Raul Abramo, Simone Albanesi +485
Einstein Telescope (ET) is the European project for a gravitational-wave (GW) observatory of third-generation. In this paper we present a comprehensive discussion of its science ob…
Multi-messenger observations in the Einstein Telescope era: binary neutron star and black hole - neutron star mergers
Alberto Colombo, Om Sharan Salafia, Giancarlo Ghirlanda +6
The Einstein Telescope (ET), a proposed next-generation gravitational wave (GW) observatory, will expand the reach of GW astronomy of stellar-mass compact object binaries to unprec…
Timing techniques applied to distributed modular high-energy astronomy: the HERMES project
A. Sanna, A. F. Gambino, L. Burderi +15
The HERMES-TP/SP (High Energy Rapid Modular Ensemble of Satellites -- Technologic and Scientific Pathfinder) is an in-orbit demonstration of the so-called distributed astronomy con…
Proton-synchrotron as the radiation mechanism of the prompt emission of GRBs?
G. Ghisellini, G. Ghirlanda, G. Oganesyan +6
We discuss the new surprising observational results that indicate quite convincingly that the prompt emission of Gamma-Ray Bursts (GRBs) is due to synchrotron radiation produced by…
Consistency with synchrotron emission in the bright GRB 160625B observed by Fermi
M. E. Ravasio, G. Oganesyan, G. Ghirlanda +4
We present time resolved spectral analysis of prompt emission from GRB 160625B, one of the brightest bursts ever detected by Fermi in its nine years of operations. Standard empiric…
Afterglows from precursors in Gamma Ray Bursts. Application to the optical afterglow of GRB 091024
F. Nappo, G. Ghisellini, G. Ghirlanda +3
About 15% of Gamma Ray Bursts have precursors, i.e. emission episodes preceding the main event, whose spectral and temporal properties are similar to the main emission. We propose…
A hint to the origin of the extended emission in LAT GRBs: the relation between LAT luminosity and prompt energetics
L. Nava, G. Vianello, N. Omodei +5
We consider the 0.1-10 GeV rest frame light curves of 10 GRBs detected by LAT and with known redshift. In all cases the emission persists after the prompt has faded away. This exte…
Short and Long GRBs: same emission mechanism?
G. Ghirlanda, G. Ghisellini, L. Nava
We study the spectral evolution on second and sub--second timescales in 11 long and 12 short Gamma Ray Bursts (GRBs) with peak flux >8.5e-6 erg/cm2 s (8 keV-35 MeV) detected by the…
Spectral properties of 438 GRBs detected by Fermi/GBM
L. Nava, G. Ghirlanda, G. Ghisellini +1
We present the results of the spectral analysis of the public data of 438 Gamma Ray Bursts (GRBs) detected by the Fermi Gamma ray Burst Monitor (GBM) up to March 2010. For 432 burs…
