Broadband Modelling of GRB 230812B Afterglow: Implications for VHE -ray Detection with IACTs

Shraddha Mohnani, Biswajit Banerjee, Davide Miceli +13

A significant fraction of the energy from the -ray burst (GRB) jets, after powering the keV-MeV emission, forms an ultra-relativistic shock propagating into the circumburst medi…

Testing the ubiquitous presence of very high energy emission in gamma-ray bursts with the MAGIC telescopes

S. Abe, J. Abhir, A. Abhishek +206

Gamma-ray bursts (GRBs) are the most powerful transient objects in the Universe, and they are a primary target for the MAGIC Collaboration. Recognizing the challenges of observing…

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…

Probing the low-energy particle content of blazar jets through MeV observations

F. Tavecchio, L. Nava, A. Sciaccaluga +1

Many of the blazars observed by Fermi actually have the peak of their time-averaged gamma-ray emission outside the GeV Fermi energy range, at MeV energies. The detail…

Cosmic-ray acceleration and escape from supernova remnant W44 as probed by Fermi-LAT and MAGIC

S. Abe, J. Abhir, A. Abhishek +218

Context. The supernova remnant (SNR) W44 and its surroundings are a prime target for studying the acceleration of cosmic rays (CRs). Several previous studies established an extende…

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…
