  The IceCube evidence for cosmic neutrinos has inspired a large number of
hypothesis on their origin, mainly due to the poor precision on the measurement
of the direction of showering events. A North/South asymmetry in the present
data set suggests the presence of a possible Galactic component. This could be
originated either by single point-like sources or from an extended Galactic
region. Expected fluxes derived from these hypotheses are presented. Some
values have been constrained from the present available upper limits from the
ANTARES neutrino telescope.
