Problems in observation of extensive air showers generated by neutrinos are connected
with an extremely small cross section of inelastic collisions of neutrinos with
nuclei. However, two facts allow to search for showers generated by neutrinos: (1) a
hadron cascade with the primary energy of more than 10^13 eV leaves a mountain ridge
to the atmosphere from the depth ~ 300g/cm^2 without an esse

We calculate the flux of neutrinos generated by the propagation of
ultra-high energy nuclei over cosmological distances. The propagation takes into
account the interactions with cosmic background radiations including the CMB
and the most recent estimates of higher energy (infra-red, optical, and ultra violet)
backgrounds. We assume that the composition of ultra-high energy cosmic rays
(UHECRs

We calculate the yield and flavor content of high energy neutrinos
produced in astrophysical sources with and without magnetic fields
varying their interaction depth.
We pay special attention to the multiple scattering of secondaries
on background photons as well as the direct production of neutrinos
in decays of charm mesons.
If multiple scattering of nucleons becomes important, the ne

Potential sources for the ultrahigh energy cosmic ray flux are
extragalactic source types such as active galactic nuclei and gama ray
busts. With the prediction of hadronic processes in these sources, a
diffuse neutrino flux ca be produced together with the charged cosmic ray
component. To measure this diffuse neutrino flux is one of the main goals
of the Antarctic Muon And Neutrino Detector

A series of ice properties' measurements were made in December, 2006 in support of
the balloon-borne ANITA neutrino detection effort. Of particular importance is the
electric field attenuation length in the range 200-1000 MHz as well as signal
transmission across the air-ice boundary. We present measurements of the temperature
profile over the upper 100 meters of ice, radiofrequency attenuatio

The RICE experiment, located at the South Pole, seeks detection of ultra-high energy
neutrinos based on measurement of the coherent radiofrequency Cherenkov pulse created
by an englacial neutrino-ice collision. Based on the eight-year dataset now
accumulated by RICE, we report on updated results on the neutrino flux in the >100
PeV energy range, limits on neutrino production from gamma-ray bur

The ANTARES collaboration is building an undersea neutrino telescope at 2400
m depth in the Mediterranean Sea. The experiment aims to detect high-energy
cosmic neutrinos using a 3D array of 900 photomultipliers (PMTs) arranged in
12 strings. The advantages of neutrinos as astrophysical and cosmic
messengers are that they open a new window to observe known astrophysical
objects as well as to l
