A search for muon neutrinos from neutralino annihilations in the Sun has been performed with the IceCube 22-string neutrino detector using data collected in 104.3 days of live time in 2007. No excess over the expected atmospheric background has been observed. Upper limits have been obtained on the annihilation rate of captured neutralinos in the Sun and(More)
Data from the AMANDA-B10 detector taken during the austral winter of 1997 have been searched for a diffuse flux of high energy extraterrestrial muon neutrinos. This search yielded no excess events above those expected from background atmospheric neutrinos, leading to upper limits on the extraterrestrial neutrino flux measured at the earth. For an assumed(More)
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(More)
The detection of extraterrestrial EHE neutrinos requires detection volumes at least one order of magnitude larger than currently constructed km optical neutrino detectors. In ice, it is anticipated that the absorption length for acoustic waves reaches up to to several kilometers. This makes ice an attractive host environment for a next generation acoustic(More)
We present the results of searches for high-energy muon neutrinos from 41 gammaray bursts (GRBs) in the northern sky with the IceCube detector in its 22-string configuration active in 2007/08. The searches cover both the prompt and a possible precursor emission as well as a model-independent, wide time window of −1 h to +3 h around each GRB. In contrast to(More)
AMANDA (Antarctic Muon And Neutrino Detector Array) is a neutrino telescope built under the southern polar icecap, and its scope is exploring the possibility to detect high energy cosmic neutrinos generated by powerful celestial objects where acceleration mechanisms can bring protons up to 10 eV. We describe the achievements and results from the AMANDA-B10(More)

On 27 December 2004, a giant gamma flare from the Soft Gamma-Ray Repeater 1806-20 saturated many satellite gamma-ray detectors, being the brightest transient event ever observed in the Galaxy. AMANDA-II was used to search for down-going muons indicative of high-energy gammas and/or neutrinos from this object. The data revealed no significant signal, so(More)
This paper briefly describes the principle of operation and science goals of the AMANDA high energy neutrino telescope located at the South Pole, Antarctica. Results from an earlier phase of the telescope, called AMANDA-BIO, demonstrate both reliable operation and the broad astrophysical reach of this device, which includes searches for a variety of sources(More)
