The exploration of the universe has recently entered a new era thanks to the multi-
messenger paradigm, characterized by a continuous increase in the quantity and quality of …

We review several current aspects of dark matter theory and experiment. We overview the
present experimental status, which includes current bounds and recent claims and hints of a …

Gamma-ray bursts (GRBs), which are bright flashes of gamma rays from extragalactic
sources followed by fading afterglow emission, are associated with stellar core collapse …

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 …

INTRODUCTION Neutrinos are tracers of cosmic-ray acceleration: electrically neutral and
traveling at nearly the speed of light, they can escape the densest environments and may be …

Galactic cosmic rays reach energies of at least a few petaelectronvolts (of the order of 1015
electronvolts). This implies that our Galaxy contains petaelectronvolt accelerators …

We present the results of the most comprehensive survey of the Galactic plane in very high-
energy (VHE) γ-rays, including a public release of Galactic sky maps, a catalog of VHE …

We report on the highest energy photons from the Crab Nebula observed by the Tibet air
shower array with the underground water-Cherenkov-type muon detector array. Based on …

Abstract The Crab Nebula is the brightest TeV gamma-ray source in the sky and has been
used for the past 25 years as a reference source in TeV astronomy, for calibration and …

The central region of the Milky Way is one of the foremost locations to look for dark matter
(DM) signatures. We report the first results on a search for DM particle annihilation signals …
