Gamma- and Cosmic-Ray observations with the GAMMA-400 Gamma-Ray telescope [PDF]
The future space-based GAMMA-400 gamma-ray telescope will operate onboard the Russian astrophysical observatory in a highly elliptic orbit during 7 years to observe Galactic plane, Galactic Center, Fermi Bubbles, Crab, Vela, Cygnus X, Geminga, Sun, and other regions and measure gamma- and cosmic-ray fluxes.

Flare Duty Cycle of Gamma-Ray Blazars and Implications for High-energy Neutrino Emission
Gamma-ray flares of blazars may be accompanied by high-energy neutrinos due to interactions of high-energy cosmic rays in the jet with photons, as suggested by the detection of the high-energy neutrino IceCube-170922A during a major gamma-ray flare from ...

Indirect detection of neutralino dark matter candidates in anomaly-mediated supersymmetry breaking scenarios [PDF]
We consider a model for neutralino dark matter candidates arising in anomaly-mediated supersymmetry breaking schemes, and examine its testability through the search for exotic cosmic rays produced by neutralino pair annihilations in the dark halo of the ...

Gamma ray transport simulations using SGaRD code
SGaRD (Spectroscopy, Gamma rays, Rapid, Deterministic) code is used for the fast calculation of the gamma-ray spectrum, produced by a spherical shielded source and measured by a detector.

Ultra-high-energy, >10^19 eV, cosmic-ray and high energy, ~10^14 eV, neutrino production in GRBs is discussed in the light of recent GRB and cosmic-ray observations. Emphasis is put on model predictions that can be tested with operating and planned cosmic-ray and neutrino detectors, and on the prospects of testing for neutrino properties.

Critical Tests of Leading Gamma Ray Burst Theories
It has been observationally established that supernovae (SNe) of Type Ic produce long duration gamma-ray bursts (GRBs) and that neutron star mergers generate short hard GRBs.

Establishment of Anti-cosmic Ray HPGe Gamma Spectrometer
Radionuclide verification is one of the four monitoring technologies used in International Monitoring System of Comprehensive Nuclear-Test-Ban Treaty (CTBT). The activity of radionuclides concerned by CTBT generally performs at the low-level.

Effect of irradiation treatment on the functional properties of flavonoid extracts
In this study, Pueraria mirifica, Hawthorn, and soy flavonoid extracts were irradiated with 60CO-γ rays to investigate the effects of different irradiation doses on the storage performance, antibacterial properties, and antioxidant activity of flavonoid
