Cooling of Accelerated Nucleons and Neutrino Emission in Gamma-Ray Bursts
نویسنده
چکیده
Using Monte Carlo simulations, we demonstrate photopion production from Fermi-accelerated protons and the resulting neutrino production in gamma-ray bursts. Unless internal shocks occur at quite large distance from the center, ultra high-energy protons are depleted by photopion production and synchrotron radiation. Internal shocks at fiducial distance cause neutrino bursts, which accompany gamma-ray bursts originating from electromagnetic cascades. Subject headings: gamma rays: bursts—cosmic rays—neutrinos

Nuclear composition of gamma-ray burst fireballs
We study three processes that shape the nuclear composition of the fireballs in gamma-ray bursts (GRBs): (1) neutronization in the central engine, (2) nucleosynthesis in the fireball as it expands and cools, and (3) spallation of nuclei in subsequent internal shocks. The fireballs are shown to have a neutron excess and a marginally successful nucleosynthesis. They are composed of free nucleons,...
متن کاملEARLY PHOTON-SHOCK INTERACTION IN A STELLAR WIND: A SUB-GeV PHOTON FLASH AND HIGH-ENERGY NEUTRINO EMISSION FROM LONG GAMMA-RAY BURSTS
For gamma-ray bursts (GRBs) born in a stellar wind, as the reverse shock crosses the ejecta, usually the shocked regions are still precipitated by the prompt MeV -ray emission. Because of the tight overlapping of the MeV photon flow with the shocked regions, the optical depth for the GeV photons produced in the shocks is very large. These high-energy photons are absorbed by the MeV photon flow ...
متن کاملStructure and Luminosity of Neutrino-cooled Accretion Disks
Neutrino-cooled hyperaccretion disks around stellar mass black holes are plausible candidates for the central engine of gamma-ray bursts. We calculate the one-dimensional structure and the annihilation luminosity of such disks. The neutrino optical depth is of crucial importance in determining the neutrino cooling rate and is in turn dependent on the electron fraction, the free nucleon fraction...
متن کاملSearch for High Energy Neutrino Emission from Gamma - Ray Bursts
The photo-meson production of pions by shock-accelerated protons could generate a burst of ∼ 10 14 eV neutrinos from gamma-ray bursts (GRBs) observable in the Antarctic Muon and Neutrino Detector Array (AMANDA) or its larger successors. Measurement of this flux can test the hypothesis that GRBs are the sources of the highest-energy cosmic rays, and GRB neutrinos could permit high-precision expe...
متن کاملHyperaccreting Neutron-Star Disks and Neutrino Annihilation
Newborn neutron stars surrounded by hyperaccreting and neutrino-cooled disks may exist in some gamma-ray bursts (GRBs) and/or supernovae (SNe). In this paper we further study the structure of such a neutron-star disk based on the two-region (i.e., inner & outer) disk scenario following our previous work, and calculate the neutrino annihilation luminosity from the disk in various cases. We inves...
