“…11, where the contributions from the two jets appear separately. It is also included in that figure the value of the upper limit that can be extracted from AMANDA-II data, (lim) ν (E ν > 1 TeV) = 2.1 × 10 −11 cm −2 s −1 (Halzen 2006), which agrees with recently published experimental results (Achterberg et al 2007). The expected sensitivity for a km 3 neutrino telescope such as IceCube, (km3) ν (E ν > 1 TeV) ≈ 2 × 10 −12 cm −2 s −1 for three years of operation, is also shown in Fig.…”

We study the spectral energy distribution of gamma rays and neutrinos in the precessing microquasar SS433 as a result of pp interactions within its dark jets. Gamma‐ray absorption due to interactions with matter of the extended disc and of the star is found to be important, as well as absorption caused by the ultraviolet and mid‐infrared radiation from the equatorial envelopment. We analyse the range of precessional phases for which this attenuation is at a minimum and the chances for detection of a gamma‐ray signal are enhanced. The power of relativistic protons in the jets, a free parameter of the model, is constrained by HEGRA data. This imposes limits on the gamma‐ray fluxes to be detected with instruments such as GLAST, VERITAS and MAGIC II. A future detection of high‐energy neutrinos with cubic kilometre telescopes such as IceCube would also yield important information about acceleration mechanisms that may take place in the dark jets. Overall, the determination of the ratio of gamma‐ray to neutrino flux will result in a key observational tool to clarify the physics of heavy jets.

“…Theoretical uncertainties, including muon propagation, the neutrino cross section, and the presence of the bedrock, each of which have been studied in previous analyses (see, e.g., Ref. [46]) add approximately 6% to the total uncertainty. The uncertainty due to Monte Carlo simulation statistics and detector exposure as well as the individual track pointing uncertainty is much smaller.…”

We present the results of a first search for self-annihilating dark matter in nearby galaxies and galaxy clusters using a sample of high-energy neutrinos acquired in 339.8 days of live time during 2009/10 with the IceCube neutrino observatory in its 59-string configuration. The targets of interest include the Virgo and Coma galaxy clusters, the Andromeda galaxy, and several dwarf galaxies. We obtain upper limits on the cross section as a function of the weakly interacting massive particle mass between 300 GeV and 100 TeV for the annihilation into bb, W+W−, τ+τ-, μ+μ−, and νν. A limit derived for the Virgo cluster, when assuming a large effect from subhalos, challenges the weakly interacting massive particle interpretation of a recently observed GeV positron excess in cosmic rays

“…At this time, there is not a single strategy for point-source searches in IceCube, so more than one approach was investigated, including a binned analysis similar to that in Achterberg et al (2007b), as well as an unbinned analysis similar to that in Abbasi et al (2009a). Simulation studies using the 22 string IceCube configuration showed that the latter approach was on average 35% more sensitive for both hard and soft point-source spectra.…”

We present new results of searches for neutrino point sources in the northern sky, using data recorded in [2007][2008] with 22 strings of the IceCube detector (approximately one-fourth of the planned total) and 275.7 days of live time. The final sample of 5114 neutrino candidate events agrees well with the expected background of atmospheric muon neutrinos and a small component of atmospheric muons. No evidence of a point source is found, with the most significant excess of events in the sky at 2.2σ after accounting for all trials. The average upper limit over the northern sky for point sources of muon-neutrinos with E −2 spectrum is E 2 Φ ν μ < 1.4 × 10 −11 TeV cm −2 s −1 , in the energy range from 3 TeV to 3 PeV, improving the previous best average upper limit by the AMANDA-II detector by a factor of 2.
