The IceCube neutrino telescope has observed for the first time a diffuse flux
of high energy neutrinos, with a possible astrophysical origin. Up to now there
are no evidence of sources and many hypothesis are still plausible in order to
explain the measured flux. In this proceeding we analyze an alternative way to
interpret the IceCube neutrinos, in terms of sum of contributions from
different sources.Comment: Prepared for the proceeding of the conference IFAE 201
