Gamma-Ray Light Curves and Spectra of Models for Type-Ia Supernovae [PDF]
, 1994 Based on detailed Monte Carlo calculations, we present gamma-ray energy deposition functions, gamma-ray light curves, and gamma-ray spectra for a large set of theoretical models of Type Ia supernovae including ''classical'' detonation and deflagration ...

Black Hole Accretion in Gamma Ray Bursts
Galaxies, 2017 We study the structure and evolution of the hyperaccreting disks and outflows in the gamma ray bursts central engines. The torus around a stellar mass black hole is composed of free nucleons, Helium, electron-positron pairs, and is cooled by neutrino ...

Gamma ray transport simulations using SGaRD code
EPJ Nuclear Sciences & Technologies, 2017 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.

Flare Duty Cycle of Gamma-Ray Blazars and Implications for High-energy Neutrino Emission
The Astrophysical Journal, 2023 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 ...

Critical Tests of Leading Gamma Ray Burst Theories
Universe, 2022 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.

Indirect detection of neutralino dark matter candidates in anomaly-mediated supersymmetry breaking scenarios [PDF]
, 2001 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 ...

Effect of irradiation treatment on the functional properties of flavonoid extracts
Applied Food Research, 2023 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
