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…
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…
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…
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 a…
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…
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…
