Abstract One century ago Viktor Hess carried out several balloon flights that led him to
conclude that the penetrating radiation responsible for the discharge of electroscopes was of …

Ultra-high-energy (UHE,> 0.1 PeV) γ-ray astronomy is rapidly evolving into an expanding
branch of γ-ray astronomy with the surprising discovery of 12 PeVatrons and the detection of …

Abstract The DArk Matter Particle Explorer (DAMPE), one of the four scientific space science
missions within the framework of the Strategic Pioneer Program on Space Science of the …

To uniformly determine the properties of supernova remnants (SNRs) at high energies, we
have developed the first systematic survey at energies from 1 to 100 GeV using data from …

Cosmic rays are particles (mostly protons) accelerated to relativistic speeds. Despite wide
agreement that supernova remnants (SNRs) are the sources of galactic cosmic rays …

Abstract The ASTRI (Astrofisica con Specchi a Tecnologia Replicante Italiana) Project led by
the Italian National Institute for Astrophysics (INAF) is developing and will deploy at the …

The Cherenkov Telescope Array (CTA) is a new observatory for very high-energy (VHE)
gamma rays. CTA has ambitions science goals, for which it is necessary to achieve full-sky …

The explosion of a supernova releases almost instantaneously about 10^ 51 51 ergs of
mechanic energy, changing irreversibly the physical and chemical properties of large …

A gamma-ray excess over background has been claimed in the inner regions of the Galaxy,
triggering some excitement about the possibility that the gamma rays originate from the …

We evaluate the current status of supernova remnants as the sources of Galactic cosmic
rays. We summarize observations of supernova remnants, covering the whole …
