GRBs and SGRs by high energy leptons showering in blazing gamma jets: are SGRs sources of EeV CRs?

D. Fargion, M. Grossi

The apparently huge energy budget of the gamma ray burst GRB 990123 led to the final collapse of the isotropic fireball model, forcing even the most skeptical to consider a beamed…

Rates of Horizontal Tau Air-Showers observable by satellites

D. Fargion, M. Grossi, M. De Santis +1

Up-going and Horizontal Tau Air-Showers, UpTaus and HorTaus, may trace Ultra High Energy Neutrino Tau Earth Skimming at the edge of the horizon. We show that such events even for m…

May Heavy hadrons of the 4th generation be hidden in our Universe while close to detection?

K. Belotsky, D. Fargion, M. Yu. Khlopov +3

Metastable quarks of 4th generation are predicted in the framework of heterotic string phenomenology. Their presence in heavy stable hadrons are usually strongly constrained; howev…

Puzzling afterglow's oscillations in GRBs and SGRs: tails of precessing Jets

D. Fargion

Damped oscillating afterglows in GRB 030329 and in SGR 1900+14 find a natural explanation in precessing gamma Jet model for both GRBs and SGRs. The very thin Jet cone (solid angle…

High Energy Neutrino and Tau Airshowers in Standard and New Physics

D. Fargion

High Energy Neutrino may lead to a New High Energy Astronomy. Neutrino interaction in matter at PeVs- EeVs may behave differently from Standard Model predictions because possible T…

Shadows of Relic Neutrino Masses and Spectra on Highest Energy GZK Cosmic Rays

D. Fargion, M. Grossi, P. G. De Sanctis Lucentini +2

The Ultra High Energy (UHE) neutrino scattering onto relic cosmic neutrinos in galactic and local halos offers an unique way to overcome GZK cut-off. The UHE nu secondary of UHE ph…
