PeV neutrons as origin of separated SS433 TeV signals

TL;DR

This paper proposes that PeV neutron beams from a past eruption of SS433 decay into electrons and protons, explaining the observed separated TeV gamma-ray signals at tens of TeV energies.

Contribution

It introduces a novel hypothesis linking PeV neutron emissions from SS433 to the separated TeV gamma-ray signals observed, suggesting a new origin for these high-energy emissions.

Findings

PeV neutron decay can produce electrons and protons at tens of TeV energies.

Decay products can generate separated gamma-ray signals via inverse Compton scattering.

A past eruption event could explain current high-energy gamma-ray observations.

Abstract

The SS433, a well-known binary system with an internal black hole, have shown since half a century, an inner (a few year light distances) twin precessing jets spirals. These beams are made by tidal forces while stripping mass from large stellar companion feeding an inner BH accretion disk and an orthogonal accelerating twin jet. From it, the radio, X gamma jet emission. A couple of years ago H.E.S.S telescope as well as HAWC and LHAASO array detectors, discovered also the surprising signature of an unexpected far twin separated gamma beam at tens TeV energy. At a hundred light years distances from its central source. We suggest that it is the legacy of a past rare eruption, a century ago, of tens PeV (10^16 eV) relativistic twin neutron beams. Their beta decay in flight at far distances, into proton, neutrino and in particular into tens TeV electrons, could feed the observed TeV gamma traces. They are originated by the same secondary tens TeV electrons emitting hard gamma, by Inverse Compton Scattering onto interstellar infrared photons.
