The presence of dark matter in the halo of our galaxy could be revealed through indirect detection of annihilation products. Dark matter annihilation is one of the possible interpretations of the recent measured excesses in positron and electron fluxes, once boost factors of the order of 10 or more are taken into account. Such boost factors are actually achievable through the velocity-dependent...

The details of what constitutes the majority of the mass that makes up dark matter in the Universe remains one of the prime puzzles of cosmology and particle physics today-80 y after the first observational indications. Today, it is widely accepted that dark matter exists and that it is very likely composed of elementary particles, which are weakly interacting and massive [weakly interacting ma...

As TeV gamma-ray astronomy progresses into the era of Cherenkov Telescope Array (CTA), there is a desire for capacity to instantaneously follow up on transient phenomena and continuously monitor flux at energies above $10^{12}$ eV. To this end, worldwide network Imaging Air Telescopes (IACTs) required provide triggers CTA observations complementary continuous monitoring. An IACT array sited in ...

A new hybrid experiment has been started by ASγ experiment at Tibet, China, since August 2011, which consists of a low threshold burst-detector-grid (YAC-II, Yangbajing Air shower Core array), the Tibet air-shower array (Tibet-III) and a large underground water Cherenkov muon detector (MD). In this paper, the capability of the measurement of the chemical components (proton, helium and iron) wit...

The first sensors of the IceCube neutrino observatory were deployed at the South Pole during the austral summer of 2004–2005 and have been producing data since February 2005. One string of 60 sensors buried in the ice and a surface array of eight ice Cherenkov tanks took data until December 2005 when deployment of the next set of strings and tanks began. We have analyzed these data, demonstrati...

The High Energy Stereoscopic System (H.E.S.S.) is an array of five imaging atmospheric Cherenkov telescopes (IACTs) to study gamma-ray emission from astrophysical objects in the Southern hemisphere. It only hybrid IACTs, composed with different collection area and footprint, individually optimised for a specific energy range. Collectively, most sensitive gamma rays range 100 GeV TeV. has been o...
