Sensitivity of an underwater Cerenkov km3 telescope to TeV neutrinos from Galactic Microquasars
In this paper are presented the results of Monte Carlo simulations on the
capability of the proposed NEMO-km telescope to detect TeV muon neutrinos
from Galactic microquasars. For each known microquasar we compute the number of
detectable events, together with the atmospheric neutrino and muon background
events. We also discuss the detector sensitivity to neutrino fluxes expected
from known microquasars, optimizing the event selection also to reject the
background; the number of events surviving the event selection are given. The
best candidates are the steady microquasars SS433 and GX339-4 for which we
estimate a sensitivity of about erg/cm s; the predicted
fluxes are expected to be well above this sensitivity. For bursting
microquasars the most interesting candidates are Cygnus X-3, GRO J1655-40 and
XTE J1118+480: their analyses are more complicated because of the stochastic
nature of the bursts.Comment: 20 pages, 3 figures, accepted by Astroparticle Physic
