TL;DR: The real-time follow-up of neutrino events is a promising approach to search for astrophysical neutrinos sources as mentioned in this paper, where the four major imaging atmospheric Cherenkov telescope arrays (IACTs) -FACT, H.E.S.S., MAGIC, and VERITAS - operate an active followup program of target-of-opportunity observations of NE alerts sent by IceCube.

TL;DR: In this paper , the authors reported the first results on a search for dark matter (DM) particle annihilation signals using new observations from an unprecedented γ-ray survey of the Galactic Center (GC) region, i.e., the Inner Galaxy Survey, at very high energies (≳100 GeV) performed with the H.E.S. array of five ground-based Cherenkov telescopes.

TL;DR: In this paper, the ARGUS detector at the e + e - storage ring DORIS II at DESY has observed the decay D s + → η'π + in two decay modes of the η'.

TL;DR: In this paper, the angular resolution limits achievable for perfect ground-based high-altitude gamma-ray air shower detectors are investigated, to serve as benchmarks for the design of real detectors.
