The detected neutrinos were not necessarily produced in the vicinity of the source of the cosmic rays as I understand it. Imagine it like a bank of fog lighting up in the night because a car with headlights is moving towards it.
- piannucci 3y agoYes; however, because of the extreme kinetic energy and momentum of the cosmic ray inputs to these collision events, the output neutrinos will be emitted in a tightly focused cone parallel to the path of the original ray. You can be fairly confident that the original source is close to the line-of-sight.
