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…
