“…The energy is estimated by evaluating the "brightness per track length" which correlates with the muon energy loss and therefore the muon energy in the detector. Two analyses have instead exploited the cascade channel [24,26]. As such an analysis is sensitive to all neutrino flavours, a scaling factor three (indicated by "/3" in the figure) is applied to make the resulting limits compatible to the muon channel limits.…”

“…of 90%. They have been derived for γ = 2.0 which results in horizontal lines in the figure. A selection of results from first-generation experiments (Macro [22], Amanda-II [23] and Baikal NT-200 [24]) is compared to the most recent results from ANTARES [25] and IceCube (IC40 [11,26] and IC59 [27]). The shown limits are for a single neutrino flavours.…”

Abstract. IceCube and ANTARES are neutrino detectors sensitive to energies from 20 GeV up to PeV. Both detectors have been completed and take data. Several years of data have been already analysed including periods with the partly assembled detectors. The primary goal of these two neutrino telescopes is the observation of astrophysical sources of neutrinos. Results from searches for such neutrinos with different strategies will be presented as well as measurements of atmospheric neutrinos which are an irreducible background for such searches, but they are an interesting study object by themselves.

“…[68]), leading to an upper bound which is ≈ 1/2 that shown in the figure for each flavor. Shown are the muon and all flavor upper bounds of the optical Cerenkov observatories AMANDA [10,11] and BAIKAL [22], the all flavor upper bounds of the coherent Cerenkov radio detectors RICE [63] and ANITA [46], and the ντ upper bound of the PAO [5]. The curve labelled "GZK" shows the muon neutrino intensity (not corrected for oscillations) expected from UHECR proton interactions with micro-wave background photons [29].…”

Cosmic-rays with energies exceeding 10 19 eV are referred to as Ultra High Energy Cosmic Rays (UHECRs). The sources of these particles and their acceleration mechanism are unknown, and for many years have been the issue of much debate. The first part of this review describes the main constraints, that are implied by UHECR observations on the properties of candidate UHECR sources, the candidate sources, and the related main open questions. In order to address the challenges of identifying the UHECR sources and of probing the physical mechanisms driving them, a "multi-messenger" approach will most likely be required, combining electromagnetic, cosmic-ray and neutrino observations. The second part of the review is devoted to a discussion of high energy neutrino astronomy. It is shown that detectors, which are currently under construction, are expected to reach the effective mass required for the detection of high energy extra-Galactic neutrino sources, and may therefore play a key role in the near future in resolving the main open questions. The detection of high energy neutrinos from extra-Galactic sources will not only provide constraints on the identity and underlying physics of UHECR sources, but may furthermore provide information on fundamental neutrino properties.

a b s t r a c tThe construction of a km 3 -scale neutrino telescope -the Gigaton Volume Detector (GVD) in Lake Baikal -is the central goal of the Baikal collaboration. During the R&D phase of the GVD project in 2008-2010 years the basic elements of GVD -new optical modules, FADC readout units, underwater communications and trigger systems -have been developed, produced and tested in situ by long-term operating prototype strings in Lake Baikal. The prototyping phase of the GVD project has been started in April 2011 with the installation of a three string array (prototype cluster) which comprises all basic elements and systems of the GVD-telescope in Lake Baikal. We describe configuration and technical design of the GVD, present selected results obtained during 2008-2010 with prototype strings, and describe configuration and design of the 2011 prototype cluster.
