Search for neutrino-induced cascades from gamma-ray bursts with AMANDA
نویسندگان
چکیده
Using the neutrino telescope AMANDA-II, we have conducted two analyses searching for neutrino-induced cascades from gamma-ray bursts. No evidence of astrophysical neutrinos was found, and limits are presented for several models. We also present neutrino effective areas which allow the calculation of limits for any neutrino production model. The first analysis looked for a statistical excess of events within a sliding window of 1 or 100 seconds (for short and long burst classes, respectively) during the years 2001-2003. The resulting upper limit on the diffuse flux normalization times E for the Waxman-Bahcall model at 1 PeV is 1.6×10 GeV cm s sr (a factor of 120 above the theoretical prediction). For this search 90% of the neutrinos would fall in the energy range 50 TeV to 7 PeV. The second analysis looked for neutrino-induced cascades in coincidence with 73 bursts detected by BATSE in the year 2000. The resulting upper limit on the diffuse flux normalization times E, also at 1 PeV, is 1.5×10 GeV cm s sr (a factor of 110 above the theoretical prediction) for the same energy range. The neutrino-induced cascade channel is complementary to the up-going muon channel. We comment on its advantages for searches of neutrinos from GRBs and its future use with IceCube.

Neutrino-Induced Cascades From GRBs With AMANDA-II
Using AMANDA-II we have performed a search for ν-induced cascades in coincidence with 73 bursts reported by BATSE in 2000. Background is greatly suppressed by the BATSE temporal constraint. No evidence of neutrinos was found. We set a limit on a WB-like spectrum, A flavors 90 = 9.5×10 −7 GeV cm s sr. The determination of systematic uncertainties is in progress, and the limit will be somewhat we...
متن کاملNeutrinos from Gamma Ray Bursts
We show that the detection of neutrinos from a typical gamma ray burst requires a kilometer-scale detector. We argue that large bursts should be visible with the neutrino telescopes under construction. We emphasize the 3 techniques by which neutrino telescopes can perform this search: by triggering on i) bursts of muons from muon neutrinos, ii) muons from air cascades initiated by high energy g...
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 کاملCooling of Accelerated Nucleons and Neutrino Emission in Gamma-Ray Bursts
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 gamm...
متن کاملSearch for gamma-ray bursts with the ANTARES neutrino telescope
Satellites that are capable of detecting gamma-ray bursts can trigger the ANTARES neutrino telescope via the real-time gamma-ray bursts coordinates network. Thanks to the “all-data-toshore” concept that is implemented in the data acquisition system of ANTARES, the sensitivity to neutrinos from gamma-ray bursts is significantly increased when a gamma-ray burst is detected by these satellites. Th...
متن کاملResults from Seven Years of AMANDA-II
AMANDA is a first-generation high energy neutrino telescope, which has taken data at the South Pole in its final configuration since 2000. Results from seven years of operation are presented here, including observation of the atmopheric neutrino flux and searches for astrophysical neutrinos from cosmic ray accelerators, gamma ray bursts, and dark matter annihilations. In 2007, AMANDA was incorp...
