Acceleration of cosmic rays in the Loop I 'supernova remnant'?

Attempts are being made to establish the origin of cosmic rays using the γ -ray method, that is, by dividing γ -ray intensity by gas-column density to chart the cosmic-ray intensity. Here we present evidence from satellite data on γ rays and from new results on the distribution of gas in the interst...

Description
Summary:Attempts are being made to establish the origin of cosmic rays using the γ -ray method, that is, by dividing γ -ray intensity by gas-column density to chart the cosmic-ray intensity. Here we present evidence from satellite data on γ rays and from new results on the distribution of gas in the interstellar medium (ISM) for an enhancement of electron and proton intensity in the Loop I supernova remnant (SNR). There follows from this a straightforward explanation for the origin of the bulk of the low-energy cosmic radiation.
