Abstract
— The recent IceCube observation of the first high-energy neutrinos has received the Physics World award for the Breakthrough of the Year 2013. In the light of this important discovery, we revisit the possibility of observing, at the IceCube detector, three Milagro sources: MGRO J2019+37, MGRO J1908+06 and MGRO J2031+41. Moreover, we present a discussion on the possible galactic origin of some of the IceCube events and we comment on the possibility that the high-energy neutrinos detected might come from a Dark Matter decay. Finally, we comment on other important consequences of this discovery, like bounds on Lorentz-invariance violation and on secret neutrino interactions.
