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: The AMANDA-II data collected during the period 2000-2003 have been analysed in a search for a diffuse flux of high-energy extra-terrestrial muon neutrinos from the sum of all sources in the Universe as mentioned in this paper.

TL;DR: Deep γ-ray observations with arcminute angular resolution of the region surrounding the Galactic Centre are reported, which show the expected tracer of the presence of petaelectronvolt protons within the central 10 parsecs of the Galaxy, and it is proposed that the supermassive black hole Sagittarius A* is linked to this PeVatron.

TL;DR: Very high energy (VHE) gamma-ray emission from the flat spectrum radio quasar (FSRQ) PKS 1222+21 (4C 21.432) was detected with the MAGIC Cherenkov telescopes during a short observation (similar to 0.5 hr) performed on 2010 June 17 as mentioned in this paper.

TL;DR: In this paper, the Digital Optical Modules (DOMs) are used to detect, digitize and timestamp the signals from optical Cherenkov-radiation photons at the South Pole.
