AMANDA: Status and latest Results

We briefly review some of the recent AMANDA results emphasizing the all flavor capabilities of the high energy neutrino telescope, important in the context of equal neutrino mixing from distant sources at Earth. Together with a report on a preliminary UHE neutrino flux limit, the course of our progress in the quest for point sources is described. Finally, a 1 year preliminary limit of AMANDA-II to neutralino cold dark matter (CDM) candidates, annihilating in the center of the Sun, for various MSSM parameter choices is presented and discussed.

Search for Supernova Neutrino-Bursts with the AMANDA Detector

The core collapse of a massive star in the Milky Way will produce a neutrino burst, intense enough to be detected by existing underground detectors. The AMANDA neutrino telescope located deep in the South Pole ice can detect MeV neutrinos by a collective rate increase in all photo-multipliers on top of dark noise. The main source of light comes from positrons produced in the CC-reaction of anti-electron neutrinos on free protons $\antinue + p \to e^+ + n$. This paper describes the first supernova search performed on the full sets of data taken during 1997 and 1998 (215 days of live time) with 302 of the detector's optical modules. No candidate events resulted from this search. The performance of the detector is calculated, yielding a 70% coverage of the Galaxy with one background fake per year with 90% efficiency for the detector configuration under study. An upper limit at the 90% c.l. on the rate of stellar collapses in the Milky Way is derived, yielding 4.3 events per year. A trigger algorithm is presented and its performance estimated. Possible improvements of the detector hardware are reviewed.

AMANDA: status, results and future

We review the status of the AMANDA neutrino telescope. We present results obtained from the four-string prototype array AMANDA-B4 and describe the methods of track reconstruction and neutrino event separation. We give also first results of the analysis of the 10-string detector AMANDA-B10, in particular on atmospheric neutrinos and the search for magnetic monopoles. We sketch the future schedule on the way to a cube kilometer telescope at the South Pole, ICECUBE
