An all-sky search for three flavors of neutrinos from gamma-ray bursts with the IceCube neutrino observatory

Abstract:

Ultra high energy cosmic rays (UHECRs), defined by energy exceeding 1018 eV, have been observed for decades (Zatsepin & Kuzmin 1966; Abbasi et al. 2008; Abraham et al. 2010), but their sources remain unknown. Gamma-ray bursts (GRBs) are among the most plausible candidates for these particles’ origins. If this hypothesis is true, neutrinos would also be produced in pg interactions at these sources. While the charged cosmic rays are deflected by galactic and intergalactic magnetic fields, neutrinos travel unimpeded through the universe and disclose their source directions. The detection of high energy neutrinos correlated with gamma-ray photons from a GRB would provide evidence of hadronic interaction in these powerful phenomena and confirm their role in UHECR production.
