Abstract: The VERITAS VHE (E > 100 GeV) gamma-ray observatory in southern Arizona is an array of four 12-m imaging air Cherenkov telescopes that has been operating continuously since 2007. It is one of the world’s most sensitive gamma-ray detectors between 100 GeV and 30 TeV. VERITAS maintains an observation program covering a broad range of scientific topics, from studies of the acceleration...

The MAGIC telescope system consists of two 17-m diameter mirror dish telescopes located at 2200m a.s.l. at the Canary Island of La Palma, in Spain. MAGIC has operated since 2004, and has produced more than 160 publications over a wide range of research areas, including astrophysics with Galactic and extragalactic objects, dark matter searches, and studies of cosmology via the propagation of...

Detection of very high energy (>100 GeV) gamma rays from Gamma Ray Bursts (GRBs) have been long awaited, in order for us to understand the mechanism of the GeV emissions that are detected by satellites such as Fermi-LAT.
The MAGIC Collaboration made tremendous efforts to discover GRBs which should be shining at the VHE regime.
The light-weight structure of the telescope enables a fast...

Very high energy (VHE) interaction between cosmic-ray proton and nuclei in the atmosphere is still not perfectly understood and efforts to improve interaction models used in simulations are ongoing, with feedback from various collider and air shower experiments.
Imaging Atmospheric Cherenkov Telescopes (IACTs) are indirect VHE gamma-ray detectors on the ground and cosmic-ray proton is a...

The distribution of cosmic rays in the Galaxy at energies above few TeVs is still
uncertain and this affects the expectations for the diuse gamma flux produced by hadronic interactions of cosmic rays with the interstellar gas. We show that the TeV gamma-ray sky
can provide interesting constraints. Namely, we compare the flux from the galactic plane measured by Argo-YBJ, HESS, HAWC and...
