The key role of high energy gamma-ray observations is described in the
context of the origin of galactic and extragalactic cosmic rays. The
achievements of recent years regarding both the experimental and
theoretical activities are highlighted, and the prospects of the field
are discussed.

The Fermi mission is operating in low Earth orbit since June 2008, and has collected more than one billion photons from the whole sky in the 100 MeV - 100 GeV band.
Thanks to the large acceptance of the Large Area Telescope, a pair-conversion telescope for high-energy electromagnetic radiation, Fermi also provided the largest high-energy cosmic-ray electron sample to date, with about 10k...

The present generation of Imaging Air Cherenkov Telescopes (IACTs) has
greatly improved our knowledge on the Very High Energy side of the Universe. The MAGIC IACTs operate in stereoscopic configuration since 2009 in La Palma, Canary Islands.
This talk will present a few of MAGIC latest and most relevant results, in particular related to the physics of extragalactic objects and...

The Cherenkov Telescope Array (CTA) will be the global, next-generation instrument for high-energy gamma-ray astronomy, with unprecedented performance in every respect. It will be an observatory with telescopes in the South and North, and will gradually become an open observatory. CTA is rapidly approaching its realisation. Construction of pre-production telescopes has commenced and data...

The Cherenkov Telescope Array (CTA), is an international project for the next generation ground-based observatory for gamma-ray astronomy in the energy range from 20 GeV to 300 TeV. The sensitivity in the core energy range will be dominated by up to 40 Medium Size Telescopes (MSTs) distributed over the northern and southern observatory sites.
The MST has a modified Davies-Cotton reflector...

VERITAS is an array of four 12-m imaging Cherenkov telescopes, sensitive to very-high energy (VHE; >100 GeV) gamma-ray photons. The science program of VERITAS includes the characterization of the VHE gamma-ray sky, the study of cosmic ray accelerators (both within and outside of the Galaxy), and other topics in astrophysics, cosmology and fundamental physics. Collaboration with...

The High Altitude Water Cherenkov (HAWC) experiment is a large field of view, continuously operated TeV gamma ray observatory located at 4,100 meters above sea level inside the Pico de Orizaba national park in Mexico. It consists of an array of 300 water Cherenkov detectors densely-spaced over an area of 22,000 square meters. The high altitude, the large active area, and the optical isolation...

The High Energy Stereoscopic System (H.E.S.S.) collaboration runs a system of meanwhile five Imaging Air Cherenkov Telescopes in the Khomas Highlands of Namibia. Observations of the sky in the photon energy range between below 100 GeV and ~100 TeV have revealed a large number of objects that are capable of efficiently accelerating particles to TeV energies. In this contribution, recent...

The supernova remnant (SNR) W49B originated from a core-collapse supernova that occurred between one and four thousand years ago, and subsequently evolved into a mixed-morphology remnant, which is interacting with molecular clouds (MC). SNR/MC associations are particularly interesting for probing the acceleration of hadrons in SNRs and consequently the origin of Galactic cosmic rays. The...

The high energy gamma-ray emission from the Sun is due to the interactions of cosmic ray (CR) protons and electrons with matter and photons in the solar environment. Such interactions lead to two component gamma-ray emission: a disk-like emission due to the nuclear interactions of CR protons and nuclei in the solar atmosphere and a space extended emission due to the inverse Compton (IC)...
