Current status and results of the experiment on recording
neutrino bursts are presented.
The observation livetime (since 1980) is 22.6 years.
The upper bound of collapse frequency in our Galaxy
is 0.10 $y^{-1}$ (90% CL).

The ANtarctic Impulsive Transient Antenna (ANITA) searches for
ultra high energy neutrinos interacting in the antarctic ice cap.
It is a long duration balloon experiment composed of an array of
broadband dual-polarized horn antennas that had its first science
flight over Antarctica in December 2006 through January 2007. ANITA
relies upon the Askaryan effect, in which a particle shower

Air-fluorescence detectors such as the High Resolution Fly's Eye (HiRes) instrument
are very sensitive to upward-going, Earth-skimming ultrahigh energy
electron-neutrino-induced showers.
This is due to the relatively large interaction cross sections of these high-energy
neutrinos and the Landau-Pomeranchuk-Migdal (LPM) effect, which is responsible for a
significant decrease in the cross secti

Many astrophysical models predict a diffuse flux of high-energy neutrinos from active
galactic nuclei and other extra-galactic sources. At muon energies above 1 TeV, the
upward-going muon flux induced by neutrinos from active galactic nuclei is expected
to exceed the flux due to atmospheric neutrinos. We have performed a search for this
astrophysical neutrino flux by looking for upward-going m

The AMANDA-II data collected during the period 2000-03 have been analysed in a search
for a diffuse flux of high-energy extra-terrestrial neutrinos from the sum of all sources in
the universe. With no excess of events seen, an upper limit on an E-2 flux of E2 Phi < 8.8
x 10-8 GeV cm-2 s-1 sr-1 was obtained. The astrophysical implications of this bound and
of others obtained for specific mo

The ANTARES telescope is being built in the Mediterranean Sea. The detector
consists of a 3D array of photomultipliers (PMTs) that detects the Cherenkov
light induced by the muons produced in neutrino interactions. Since the
neutrino fluxes from point-like sources are expected to be small, it is of
the utmost importance to take advantage of the ANTARES accurate pointing
power (angular resolut

A method is presented for the identification of high-energy neutrinos from
gamma ray bursts by means of a large-scale neutrino telescope.
The procedure makes use of a time profile stacking technique of observed
neutrino induced signals in correlation with satellite observations.
By selecting a rather wide time window, a possible difference between the
arrival times of the gamma and neutrino

The Pierre Auger Observatory has the capability of detecting
ultra-high energy neutrinos by searching for very inclined showers
with a significant electromagnetic component. In this work we discuss
the discrimination power of the instrument for ultra-high energy
neutrinos. Based on the data collected since January 2004 an upper
limit to the diffuse flux of neutrinos at EeV energies is presen

We perform a study of the ultra high energy neutrino detection performances of

NEMO and NESTOR in the Mediterranean sea. We focus on the effect of the
underwater surface profile on the total amount of yearly expected tau and mu

AMANDA is a high volume neutrino telescope designed to search in the down-going direction for muons from
astrophysical muon-neutrinos. It is possible to extend the range of AMANDA to search for neutrinos with
extremely high energies. The atmospheric neutrino flux becomes negligible above 10^15 eV, so this value serves
as rough energy threshold for this search. Above 10^16 eV the Earth is ess

The construction of the IceCube Neutrino Observatory began during the austral summer
of 2004-05, and is expected to continue through 2011. During 2006, nine of the
projected 80 strings were already deployed and taking data, making IceCube an
operational neutrino observatory while still at about 10% of its final size. We
present the first results of a point-source search based on the analysis o

Current point source searches mostly apply only the direction of the reconstructed
event; furthermore, they reduce available information by grouping events into sky
bins. In this analysis we use a search based on maximum likelihood techniques,
utilizing both event direction and energy, to enhance our ability to detect point
sources. Especially, use of energy information allows us to fit the sp

The Antarctic Muon And Neutrino Detector Array (AMANDA) is a Cherenkov
detector deployed in the Antarctic ice cap at the South Pole.
The charged-current interaction of high-energy electron or tau neutrinos,
as well as neutral-current interactions of neutrinos of any flavor, can
produce isolated electromagnetic or hadronic cascades.
There are several advantages associated with the cascade chan

detector containing 50,000 tons of pure water with 22,500 tons of fiducial

Supernova relic neutrinos (SRN) is diffuse supernova neutrino background from
all past supernova. No experiments have succeeded in detecting SRN yet.
Measurement of SRN enable us investigate history of past supernova. For
example, the flux of SRN shows star formation rate and supernova rate in
galaxies.
A search for SRN was conducted using Super-Kamiokande (SK) data. SK is a

We use CORSIKA+Herwig simulation code to produce ultra-high energy neutrino
interactions in the atmosphere. Our aim is to reproduce extensive air showers
originated by extragalactic tau-neutrinos. As we have no code available which can
simulate the tau-neutrino as primary particle in the atmosphere, we use muon-neutrino
as primaries. For charged current tau-neutrino interactions in the atmosph

France.
