TL;DR: In this article, the Pierre Auger Collaboration has reported evidence for anisotropies in the arrival directions of cosmic rays with energies larger thanEth = 55 EeV and showed that there is a correlation above the isotropic expectation with nearby active galaxies and the largest excess is in a celestial region around the position of the radio galaxy Cen A.

TL;DR: The Cherenkov Telescope Array (CTA) as mentioned in this paper is the major global observatory for very high energy gamma-ray astronomy over the next decade and beyond, covering a huge range in photon energy from 20 GeV to 300 TeV.

TL;DR: In this article, the authors presented the first joint analysis of gamma-ray data from the MAGIC Cherenkov telescopes and the Fermi Large Area Telescope (LAT) to search for gamma signals from dark matter annihilation in dwarf satellite galaxies, and obtained limits on the annihilation cross-section for dark matter particle masses between 10 GeV and 100 TeV.

TL;DR: In this article, the teraelectronvolt emission from the γ-ray burst GRB 190114C was observed in the energy range 0.2 − 1 teralectron volt from about one minute after the burst (at more than 50 standard deviations in the first 20 minutes), revealing a distinct emission component with power comparable to that of the synchrotron component.

TL;DR: Observations of teraelectronvolt emission from the γ-ray burst GRB 190114C reveal a distinct component of the afterglow emission with power comparable to that of the synchrotron emission.
