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 …

The recent detection of 12 γ-ray galactic sources well above E> 100 TeV by the LHAASO
observatory has been a breakthrough in the context of the search for the origin of cosmic …

Observations of the Milky Way at TeV–PeV energies reveal a bright diffuse flux of hadronic
cosmic rays and also bright point sources of gamma rays. If the gamma-ray sources are …

In the Large High Altitude Air Shower Observatory (LHAASO), the square kilometer array,
with 5249 electromagnetic particle detectors (EDs) and 1188 muon detectors, is deployed to …

We present a simple phenomenological model of hadronic interaction between protons
accelerated in an old supernova remnant (SNR) and cold protons situated within the …

HEX-P is a probe-class mission concept that will combine high spatial resolution X-ray
imaging (< 1 0 ″FWHM) and broad spectral coverage (0.2–80 keV) with an effective area …

The Pevatron test statistic (PTS) is applied to data from γ-ray observatories to test for the
origin of cosmic rays (CRs) at energies around the knee of the CR spectrum. Several …

Context. The search for Galactic PeVatrons–astrophysical accelerators of cosmic rays to
PeV energies–has entered a new phase in recent years with the discovery of the first ultra …

Context. The Large High Altitude Air Shower Observatory (LHAASO) has detected multiple
ultra-high-energy (UHE; E γ≥ 100 TeV) gamma-ray sources in the Milky Way Galaxy, which …

Abstract The Very Energetic Radiation Imaging Telescope Array System (VERITAS) is an
array of four 12 m Imaging Atmospheric Cherenkov Telescopes (IACTs), located at the Fred …
