High energy time lags of Gamma Ray Bursts
C. Maraventano, G. Ghirlanda, L. Nava +5
Positive lags between the arrival time of different photon energies are commonly observed in Gamma-Ray Bursts (GRBs), where soft photons lag behind harder ones. However, some GRBs…
HERMES Pathfinder & SpIRIT: a progress report
F. Fiore, M. Trenti, Y. Evangelista +87
HERMES Pathfinder is an in-orbit demonstration consisting of a constellation of six 3U cubesats hosting simple but innovative X-ray/gamma-ray detectors for the monitoring of cosmic…
HERMES: Gamma Ray Burst and Gravitational Wave counterpart hunter
G. Ghirlanda, L. Nava, O. Salafia +67
Gamma Ray Bursts (GRBs) bridge relativistic astrophysics and multi-messenger astronomy. Space-based gamma/X-ray wide field detectors have proven essential to detect and localize th…
Soft X-ray prompt emission from a high-redshift gamma-ray burst EP240315a
Y. Liu, H. Sun, D. Xu +191
Long gamma-ray bursts (GRBs) are believed to originate from core collapse of massive stars. High-redshift GRBs can probe the star formation and reionization history of the early un…
