Search for extraterrestrial point sources of neutrinos with AMANDA-II.

چکیده
We present the results of a search for point sources of high-energy neutrinos in the northern hemisphere using AMANDA-II data collected in the year 2000. Included are flux limits on several active-galactic-nuclei blazars, microquasars, magnetars, and other candidate neutrino sources. A search for excesses above a random background of cosmic-ray-induced atmospheric neutrinos and misreconstructed downgoing cosmic-ray muons reveals no statistically significant neutrino point sources. We show that AMANDA-II has achieved the sensitivity required to probe known TeV gamma-ray sources such as the blazar Markarian 501 in its 1997 flaring state at a level where neutrino and gamma-ray fluxes are equal.

Search for Neutrino-Induced Cascades with the AMANDA-II Detector
The first generation of large open water/ice Cherenkov telescopes has recently started operation. The goal of these instruments is the detection of an astrophysical high-energy neutrino flux which, if detected would add crucial information to the puzzle of the origin of the high-energy cosmic rays. AMANDA (Antarctic Muon And Neutrino Detector Array) is located at the geographical South Pole and...
متن کاملNeutrino Astronomy at the South Pole: latest Results from AMANDA-II
AMANDA-II is the largest neutrino telescope collecting data at the moment, and its main goal is to search for sources of high energy extra-terrestrial neutrinos. The detection of such sources could give non-controversial evidence for the acceleration of charged hadrons in cosmic objects like Supernova Remnants, Micro-quasars, Active Galactic Nuclei or Gamma Ray Bursts. No significant excess has...
متن کاملAMANDA 7-Year Multipole Analysis
The multipole analysis investigates the arrival directions of registered neutrino events in AMANDA-II by a spherical harmonics expansion. The expansion of the expected atmospheric neutrino distribution returns a characteristic set of expansion coefficients. This characteristic spectrum of expansion coefficients can be compared with the expansion coefficients of the experimental data. As atmosph...
متن کاملSearch for Cosmic Point Sources of High Energy Neutrinos with the AMANDA-II Detector
We describe the search for astrophysical sources of high energy neutrinos with the AMANDA-II detector. This detector allows for reconstruction of neutrino induced muon tracks by the Cherenkov radiation emitted by relativistic muons. We analyze the AMANDA-II data recorded in the year 2000 with a lifetime of 197 days. A large fraction of the background of atmospheric muons can be suppressed by th...
متن کاملSearches for signals from cosmic point-like sources of high energy neutrinos in 5 years of AMANDA-II data
AMANDA-II is a neutrino telescope located in the glacial ice at the South Pole. It is optimized to detect neutrino induced muon tracks with energies larger than 100 GeV by their Čerenkov light emission. We analyzed the data collected in 1001 effective days of detector operation between the years 2000 and 2004 for a signal from point-like sources of neutrinos. Such a signal is expected from cosm...
