The IceCube Neutrino Observatory is a multi-component detector at the South Pole. Besides studying high-energy neutrinos, it capable of measuring cosmic rays from PeV to EeV. This energy region thought cover transition galactic extragalactic sources rays. observatory consists deep in-ice array, which measures (≥500 GeV) muonic component, and IceTop surface sensitive electromagnetic low-energy p...

Abstract M31 and M33 are the closest spiral galaxies largest members (together with Milky Way) of Local group, which makes them interesting targets for indirect dark matter searches. In this paper we present studies expected sensitivity Cherenkov Telescope Array (CTA) to an annihilation signal from weakly interacting massive particles M33. We show that a 100 h long observation campaign will all...

We describe here a new concept of a Cherenkov detector for particle identification by means of measuring the Time-of-Propagation (TOP) of Cherenkov photons.

In high energy physics, unknown particles are identified by determining their mass from the Cherenkov radiation cone that is emitted as they pass through the detector apparatus. However, at higher particle momentum, the angle of the Cherenkov cone saturates to a value independent of the mass of the generating particle, making it difficult to effectively distinguish between different particles. ...

We are developing technologies in processing and metrology to fabricate a 1.4-meter aperture, aspherical surface Aluminium prototype mirror for Cherenkov Telescope Array. The aim is fast process these large aperture mirrors at low cost. technical development will ensure the high specifications on quality. Different methods including Swinging Arm Profilometry (SAP) phase measuring deflectomtry (...

The prototype Schwarzschild-Couder Telescope (pSCT) is a candidate for medium-sized telescope in the Cherenkov Array. pSCT based on novel dual mirror optics design which reduces plate scale and allows use of silicon photomultipliers as photodetectors. camera currently has only central sector instrumented with 25 modules (1600 pixels), providing 2.68$^{\circ}$ field view (FoV). electronics are c...
