112. Analysis of the cumulative neutrino flux from FERMI-LAT blazar populations using 3 years of IceCube data

Sig. Thorsten Glüsenkamp (DESY)

01/10/14, 14:00

The recent discovery of a diffuse neutrino flux around PeV energies raises the question which populations of astrophysical sources contribute to this diffuse signal. One extragalactic candidate source population to produce high-energy neutrinos are Blazars. We present results from a likelihood analysis searching for cumulative neutrino emission from Blazar populations selected with the 2nd...

110. Constraints to a Galactic component of the Ice Cube cosmic neutrino flux

The IceCube evidence for cosmic neutrinos in the high-energy starting events (HESE) sample has suggested a large number of hypothesis for their origin. The fact that most of HESE are downward going suggests a possible Galactic origin for a fraction of the signal. The hypothesis of a Galactic component of the IceCube signal, either considering a cluster of events from a single point-like...

169. Semi-relativistic hypernova as sources of PeV neutrinos

We argue that the excess of sub-PeV/PeV neutrinos recently reported by IceCube could plausibly originate through pion-production processes in the same sources responsible for cosmic rays (CRs) with energy above the second knee around 10^{18}eV. The pion production efficiency for escaping CRs that produce PeV neutrinos is required to be >0.1 in such sources. On the basis of current data, we...

101. Galactic sources of high energy neutrinos

Dr. Narek Sahakyan (National Academy of Sciences of the Republic of Armenia and ICRANet)

The recent results from ground based gamma-ray detectors (HESS, MAGIC, VERITAS) provides a population of TeV galactic gamma-ray sources which are potential sources of high energy neutrinos. Since the gamma-rays and neutrinos are produced from decays of neutral and charged pions, the flux of TeV gamma-rays can be used to estimate the upper limit of neutrino flux and vice versa; detectability of...

117. Cascade sensitivity studies for KM3NeT

Luigi Antonio Fusco (BO)

01/10/14, 15:20

KM3NeT is a future research infrastructure in the deep sea of the Mediterranean, hosting the next generation neutrino telescope. The instrumented volume of the telescope, of several cubic kilometers, will be split up in six smaller building block. The construction of the first phase of the telescope is in progress. The next step, internally named KM3NeT Phase 1.5, is to realize the first two...
