Some possible sources of IceCube TeV-PeV neutrino events

Understand

The IceCube Collaboration has observed 37 neutrino events in the energy range $30\, TeV\leq E_{\nu} \leq 2$ PeV and the sources of these neutrinos are unknown.

• Here we have shown that positions of 12 high energy blazars and the position of the FR-I galaxy Centaurus A, coincide within the error circles of ten IceCube events, the later being in the error circle of the highest energy event so far observed by IceCube.
• Two of the above blazars are simultaneously within the error circles of the Telescope Array hotspot and one IceCube event.
• We found that the blazar H2356-309 is within the error circles of three IceCube events.
