I will discuss the model dependence of the neutrino flux in the
GeV to EeV range implied in the common GRB paradigm, in the light
of recent IceCube constraints. Possible differences in the neutrino
spectra expected in some recent variations on the GRB model will
also be reviewed.

The IceCube Neutrino Observatory is a kilometer-scale detector located in the South
Pole. The full detector comprises 5,160 photomultipliers (PMTs) deployed along 86
strings from 1.5-2.5 km deep in the ice. The detector construction finished during
the Austral summer of 2010-11. In addition, a dense sub-array of 6 strings in the
center of the detector together with 7 surrounding...

Neutrino astronomy plays a major role in the understanding of cosmic particle
acceleration mechanisms and so may provide valuable information about the properties
of the sources of the highest energy particles in the Universe. Another promising
area of research of a neutrino telescope lies in the indirect search for dark matter
particles or particles beyond the Standard Model. ANTARES, the...

The ANTARES detector is the first full operational and the largest underwater
neutrino telescope in the Northern Hemisphere. Located at 40 km offshore the coast of
Toulon, it consists of 12 detection lines anchored to the seabed at a depth of 2475 m
and divided on 25 foors (or storeys) composed by a triplet of photomultiplier tubes
(PMTs). This three-dimensional photo-detector array...

The construction of the IceCube neutrino observatory was completed in December 2010
and the detector is now operating with 86 strings and 5160 optical modules.
The detector has been taking data in different configurations while
construction took place. We present recent results from the searches for dark matter
candidates with IceCube using the Sun and the Galactic Center and Halo as...

Typical analyses of neutrino telescope data for signals of WIMP annihilation in the
Sun assume some particular annihilation final states. Upper limits are drawn on
WIMP-nucleon scattering cross-sections as a function of the WIMP mass, which must
then be interpreted in terms of specific particle theories such as supersymmetry.
This interpretation is often complicated by the question of...

The ANTARES neutrino telescope was completed in 2008 after the installation of its
twelfth line. Its scientific scope is very broad, but the two main goals are the
observation of astrophysical neutrino sources and the indirect detection of dark
matter. The latter is possible through the detection of neutrinos produced after the
annihilation of WIMPs, which would accumulate in sources like...

Cosmogenic neutrinos with energy up to ~10^{11} GeV originate from photo-
hadronic interactions of UHECR protons with the CMB and the accompanying EM
cascades generate a diffuse gamma-ray background in the GeV-TeV region. Thus
Fermi-LAT measurements of the extragalactic gamma-ray flux constrain the
cosmogenic flux and, indirectly, the UHECR source spectrum and its cosmological...

The Pierre Auger Observatory is a hybrid detector of Ultra High Energy Cosmic Rays.
It has the capability of detecting ultra-high energy neutrinos of all flavours above
10$^{17}$ eV. The method adopted is to search for very inclined showers produced
close to the detector. The properties of such showers that start deep in the
atmosphere are different at ground level from those showers...

Simultaneous observations in different wavelengths are critical for understanding the
high energy universe. The IceCube Neutrino Observatory offers the possibility to
view the universe through the neutrino window, to distinguish hadronic and leptonic
processes and to peer inside regions opaque to EM radiation. In many cases, the
neutrinos may also be the first messengers to arrive, and...
