Please explain for the layman that I am, how can these neutrinos be so energetic ? I thought neutrinos were very elusive particles that don't interact much with matter, and that's why they're so difficult to detect. With that much energy, these neutrinos should interact with matter and do heavy 'damage', àla cosmic particles, no ?
byAnonymous Coward writes:
One of the properties that IceCube takes advantage of is that at higher energies, neutrinos are much more likely to interact with matter and produce particles that it can detect. There's actually a specific energy close to the observed energy of these particles for an electron anti-neutrino where there is a spike in the probability to interact with electrons (6.3 PeV, the Glashow resonance).
