TL;DR: The ground-based gamma-ray astronomy has had a major breakthrough with the impressive results obtained using systems of imaging atmospheric Cherenkov telescopes as mentioned in this paper, which is an international initiative to build the next generation instrument, with a factor of 5-10 improvement in sensitivity in the 100 GeV-10 TeV range and the extension to energies well below 100GeV and above 100 TeV.

TL;DR: In this article, the authors used pulsed and continuous light sources embedded with the AMANDA neutrino telescope, an array of more than six hundred photomultiplier tubes buried deep in the ice.

TL;DR: The atmospheric Cherenkov gamma-ray telescope MAGIC, designed for a low-energy threshold, has detected very-high-energy gamma rays from a giant flare of the distant Quasi-Stellar Radio Source 3C 279, at a distance of more than 5 billion light-years.

TL;DR: An upper limit on the flux of energetic neutrinos associated with GRBs that is at least a factor of 3.7 below the predictions is reported, implying either that GRBs are not the only sources of cosmic rays with energies exceeding 1018 electronvolts or that the efficiency of neutrino production is much lower than has been predicted.

TL;DR: Limits are derived on the velocity-weighted annihilation cross section (σv) as a function of the DM particle mass that are among the best reported so far for this energy range and in particular differ only little between the chosen density profile parametrizations.
