A.U. Kudzhaev for the "Carpet-3" collaboration.
At present at the Baksan Neutrino Observatory of INR RAS a preparation of experiment for measuring a flux of cosmic diffuse gamma radiation with energy higher than 100TeV (experiment “Carpet-3”) is carried out. The preparation of the experiment will be propose of enlarge the area both of muon detector and ground part of shower array. At the...

The DArk Matter Particle Explorer (DAMPE), is a space mission within the strategic framework of the Chinese Academy of Sciences, resulting from a collaboration of Chinese, Italian, and Swiss institutions, is a new addition to the growing number of particle detectors in space. It was successfully launched in December 2015 and has commenced nominal science operations since shortly after launch....

The recent results of the very precise measurements of the primary cosmic protons and helium nuclei energy spectra by AMS-02, PAMELA, CREAM, ATIC-2 and some other collaborations and some rather accurate estimates of these proton and helium nuclei energy spectra generated in SNR allow us to elaborate the new high acuracy original approximation of the pimary nucleon energy spectra. As the...

The Large Area Telescope onboard the Fermi satellite is a pair-conversion telescope for high-energy gamma rays of astrophysical origin. Although it was designed to be a high-sensitivity gamma-ray telescope, the LAT has proved to be an excellent electron/positron detector. It has been operating in low Earth orbit since June 2008 and has collected more than 16 millions of cosmic-ray electron and...

The first version of the theoretical model of friable nuclear matter is developed, which is based on the resonance interaction of protons with $\alpha$-particles. These interactions, manifested in Laboratory experiments in the form of unstable nuclei such as ${}^5{\rm Li}$, ${}^6{\rm Be}$ and others, can lead to the formation of quasistationary and, possibly, even stable nuclear-molecular...

Experiments which search for dark matter by detecting its extremely weak interactions with nuclei have employed a variety of techniques. The technologies developed by this set of "direct detection" experiments have matured and are now available for scaling up to much larger and more sensitive detectors. The LZ experiment, which utilizes the two-phase xenon time projection chamber technique,...

In space, ultra-high energy cosmic rays interact with cosmic microwave background and thus dissipate energy. This results in a lack of particles at energies about 10^20 eV at the Earth (GZK-effect) if cosmic rays come from distances of more than $\sim$100 Mpc. Another effect of interaction with cosmic microwave background is electromagnetic cascades that particles initiate in extragalactic...

It is commonly accepted that the main sources of cosmic rays in the Galaxy are the supernovae explosions. Protons, nuclei and electrons are accelerated by shock waves produced by supernovae explosions. According to theory, maximum energy of accelerated protons can be as much as 10^16 eV. For nuclei it is Z times higher where Z is a nucleus electric charge. Other sources of cosmic rays cold be...

In 2008 the PAMELA magnetic spectrometer has discovered unpredicted abundance of the ratio of the galactic positron flux to the total positrons and electrons flux at high energies. It does not agree with the cosmic rays fluxes calculated using GALPROP routine. This abundance was called the “anomalous effect PAMELA” and one of the explanations of this effect was the appearance of the additional...
