Observations of Markarian 421 with the MAGIC Telescope [PDF]

The Astrophysical Journal, 2007
The MAGIC telescope took data of very high energy gamma-ray emission from the blazar Markarian 421 ( Mrk 421) between 2004 November and 2005 April. We present a combined analysis of data samples recorded under different observational conditions, down to gamma- ray energies of 100 GeV. The flux was found to vary between 0.5 and 2 crab ( integrated above

Gamma-Ray Bursts Afterglow Physics and the VHE Domain

Galaxies, 2022
Afterglow radiation in gamma-ray bursts (GRB), extending from the radio band to GeV energies, is produced as a result of the interaction between the relativistic jet and the ambient medium.
