Indirect Dark Matter Detection Using Cherenkov Telescopes

The topic of this report pertains to the detection and analysis of γ-rays emitted from the galactic center (GC) using the Very Energetic Radiation Imaging Telescope Array System (VERITAS), a Cherenkov array system. The specific cause of γ-ray production around this region is speculated to be Dark Matter (DM). DM is an extension of the current standard model. The evidence for DM is so plentiful,...

Clusters in the Arrival Directions of 2 × 1017-eV Cosmic Rays Detected at the Yakutsk EAS Array

1. Primary cosmic radiation (PCR) of ultrahigh energies (E0 > 4 × 1017 eV) is thought to consist primarily of charged particles, protons, and nuclei of various chemical elements. These charged particles are strongly mixed by the magnetic field of the galaxy and distributed almost isotropically over the celestial sphere. For this reason, it is difficult to find the local sources of PCR. The abov...

5 - a 5 GeV energy threshold array of imaging atmospheric Cherenkov telescopes at 5 km altitude

We discuss the concept and the performance of a powerful future ground-based astronomical instrument, 5@5 a 5 GeV energy threshold stereoscopic array of several large imaging atmospheric Cherenkov telescopes installed at a very high mountain elevation of about 5 km a.s.l. for the study of the γ-ray sky at energies from approximately 5 GeV to 100 GeV, where the capabilities of both the current s...
