Solving the missing GRB neutrinos and the GRB-SN puzzles | Daniele Fargion
; Pietro Oliva
; | Date: |
1 May 2016 | Abstract: | We argue that any GRB model where the progenitor is made by high relativistic
hadronic interactions shock waves, and later on by electron-pairs feeding gamma
jets, is necessarily leading to an average high neutrino over photon fluency
ratio well above unity, mostly above several thousands. The present observed
average highest energy ICECUBE neutrino energy fluency is at most comparable to
the gamma-X in GRB one. Therefore no hadronic GRB, Fireball or even any
earliest hadronic thin precessing Jet, may fit the observation. We therefore
imagine a novel electronic thin spinning and precessing jet, fed in late binary
system, able to avoid the overcrowded neutrino tails foreseen in hadronic GRB
models. In some occasion such an electronic model may lead to an explosion that
shines during a GRB with an (apparent) late SN-like event. | Source: | arXiv, 1605.0177 | Services: | Forum | Review | PDF | Favorites |
