Comments
The Nature paper concludes: "The joint Poisson probability of such a configuration (one event in KM3NeT and zero in IceCube and Auger) is about 0.5% (2.6Ο)."
Are there any paper with more details or ideas than this?
Please also have a look at the supplementary material of the Nature paper: https://www.nature.com/articles/s41586-024-08543-1#Sec18, as well as the companion papers published on ArXiv: 2502.08173, 2502.08508, 2502.08484 and 2502.08387.
More papers will follow from our side, and we assume also from others ;-)
If it is cosmogenic, then these sort of analyses are relevant.
Please help me out with information which might be somewhere in the papers you link.
1) If it is a transient point source, would it be visible by IceCube ?
2) Have HESS and MAGIC observed this region as a target?
Such high-energy neutrinos are expected from different possible origins: cosmic accelerators or cosmogenic neutrinos
According to simulations for muons with the same position and direction as KM3-230213A we recorded a muon of 120 PeV and derived from that a #RecordNeutrino energy of 220 PeV
