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…
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 med…
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…
Galactic transient sources with the Cherenkov Telescope Array Observatory
Cherenkov Telescope Array Observatory Consortium
A wide variety of Galactic sources show transient emission at soft and hard X-ray energies: low- and high-mass X-ray binaries containing compact objects, isolated neutron stars exh…
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…
