No Tau? No Astronomy!
Daniele Fargion, Pietro Oliva

TL;DR
The paper questions the current understanding of astrophysical neutrinos by highlighting the lack of expected tau neutrino signatures and correlations, suggesting that prompt atmospheric neutrinos may explain IceCube observations instead.
Contribution
It proposes that the absence of tau neutrino signals and correlations challenges the neutrino astronomy paradigm, favoring atmospheric origins.
Findings
No observed tau neutrino signatures like double bangs or airshowers.
Lack of correlations with known astrophysical sources.
Possible explanation by prompt atmospheric neutrinos.
Abstract
Since 2013 IceCube cascade showers sudden overabundance have shown a fast flavor change above 30-60 TeV up to PeV energy. This flavor change from dominant muon tracks at TeVs to shower events at higher energies, has been indebted to a new injection of a neutrino astronomy. However the recent published 54 neutrino HESE, high energy starting events, as well as the 38 external muon tracks made by trough going muon formed around the IceCube, none of them are pointing to any expected X-gamma or radio sources: no one in connection to GRB, no toward active BL Lac, neither to AGN source in Fermi catalog. No clear correlation with nearby mass distribution (Local Group), nor to galactic plane. Moreover there have not been any record (among a dozen of 200 TeV energetic events) of the expected double bang due to the tau neutrino birth and decay. An amazing and surprising unfair distribution in…
