- Abstract:Hadronic interactions of cosmic protons and nuclei with the ambient gas lead
to the production of both neutrinos and gamma-rays. Both types of secondary
particles can be used to provide information on sites of cosmic-ray
acceleration. As messengers gamma-rays have a clear advantage in that
sensitive detectors can be readily constructed. However, despite the
difficulty of experimental neutrino astronomy, neutrinos have the advantage
that they point unambiguously to the presence of a *hadronic* component of
cosmic rays. The recent progress made in galactic TeV gamma-ray astronomy
using the H.E.S.S. instrument provides for the first time a population of
galactic sources for which the neutrino flux can be estimated. Using new
parameterisations of pion production and decay in hadronic interactions and
gamma-ray spectra measured using H.E.S.S. we estimate the signal and
background rates expected for these sources in the ANTARES and KM3NeT
detectors. Although, generally these estimates should be considered as flux
upper limits, we discuss the conditions and type of gamma-ray sources for
which one can provide robust neutrino flux predictions.
