Ground-based γ-ray astronomy, which provides access to the TeV energy range, is a young
and rapidly developing discipline. Recent discoveries in this waveband have important�…

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 main objectives of the KM3NeT Collaboration are (i) the discovery and subsequent
observation of high-energy neutrino sources in the Universe and (ii) the determination of the�…

Introduction Neutrino observations are a unique probe of the universe's highest-energy
phenomena: Neutrinos are able to escape from dense astrophysical environments that�…

A search for high-energy neutrinos interacting within the IceCube detector between 2010
and 2012 provided the first evidence for a high-energy neutrino flux of extraterrestrial origin�…

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 γ-ray sky> 100 MeV is dominated by the diffuse emissions from interactions of cosmic
rays with the interstellar gas and radiation fields of the Milky Way. Observations of these�…

We provide an updated assessment of the power of the Cherenkov Telescope Array (CTA)
to search for thermally produced dark matter at the TeV scale, via the associated gamma-ray�…

We present the first catalog of TeV gamma-ray sources realized with data from the newly
completed High Altitude Water Cherenkov Observatory (HAWC). It is the most sensitive wide�…

The past decade has brought impressive advances in the astrophysics of cosmic rays (CRs)
and multiwavelength astronomy, thanks to the new instrumentation launched into space and�…
