Detection potential of the KM3NeT detector for high-energy neutrinos from the Fermi bubbles

A recent analysis of the Fermi Large Area Telescope data provided evidence for a high-intensity emission of high-energy gamma rays with a E 2 spectrum from two large areas, spanning 50 above and below the Galactic centre (the ‘‘Fermi bubbles’’). A hadronic mechanism was proposed for this gamma-ray emission making the Fermi bubbles promising source candidates of high-energy neutrino emission. In this work Monte Carlo simulations regarding the detectability of high-energy neutrinos from the Fermi bubbles with the future multi-km3 neutrino telescope KM3NeT in the Mediterranean Sea are presented. Under the hypothesis that the gamma-ray emission is completely due to hadronic processes, the results indicate that neutrinos from the bubbles could be discovered in about one year of operation, for a neutrino spectrum with a cutoff at 100 TeV and a detector with about 6 km3 of instrumented volume. The effect of a possible lower cutoff is also considered.Published7–141.8. Osservazioni di geofisica ambientaleJCR Journalrestricte

KM3NeT. Conceptual Design Report for a Deep-Sea Research Infrastructure Incorporating a Very Large Volume Neutrino Telescope in the Mediterranean Sea

The scientific case for a neutrino telescope of a cubic kilometre scale is overwhelming. The infra‐structure it requires can easily be shared by a host of other, associated, sciences, making long‐term measurements in the area of oceanography, clima‐tology, geophysics, geotechnics and marine bio‐logical sciences possible. This combination of neu‐trino telescope and multidisciplinary undersea ob‐servatory, KM3NeT, is the subject of this Design Report. It summarises goals for the design and the options for its technical implementation

KM3NeT: Technical design report.

KM3NeT is a deep‐sea multidisciplinary observatory in the Mediterranean Sea that will provide innovative science opportunities spanning Astroparticle Physics and Earth and Sea Science. This is possible through the synergy created by the use of a common infrastructure allowing for long term continuous operation of a neutrino telescope and marine instrumentation. The present KM3NeT Design Study concludes with this Technical Design Report which develops the ideas put forward in the Conceptual Design Report published in April 2008
