[seminar] Niccolo' Loret 18.05. (srijeda) 11:30h, seminar ZTF-a

[Fabrizio Nesti]

I’ll not be there, but I have a question for the seminar. 

When using the time of flight to assess the dispersion relation -- are we sure the emission of neutrino and GRB are simultaneous, or given by a known dynamics and/or energy dependence? 

Thanks, 
f
