The search for Galactic pevatrons is now a well-identified key science project of all
instruments operating in the very-high-energy domain. Indeed, in this energy range, the …

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 …

The extension of the cosmic-ray spectrum beyond 1 petaelectronvolt (PeV; 1015
electronvolts) indicates the existence of the so-called PeVatrons—cosmic-ray factories that …

The highest-energy gamma-rays from gamma-ray bursts (GRBs) have important implications
for their radiation mechanism. Here we report the detection of gamma-rays up to 13 …

The Crab Nebula is a bright source of gamma rays powered by the Crab Pulsar's rotational
energy through the formation and termination of a relativistic electron-positron wind. We …

The diffuse Galactic γ-ray emission, mainly produced via interactions between cosmic rays
and the interstellar medium and/or radiation field, is a very important probe of the …

We report the discovery of an extended very-high-energy (VHE) gamma-ray source around
the location of the middle-aged (207.8 kyr) pulsar PSR J 0622+ 3749 with the Large High …

We present the first catalog of very-high-energy and ultra-high-energy gamma-ray sources
detected by the Large High Altitude Air Shower Observatory. The catalog was compiled …

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 …

We report the detection of a γ-ray bubble spanning at least 100 deg 2 in ultra-high energy
(UHE) up to a few PeV in the direction of the star-forming region Cygnus X, implying the …
