Abstract
Gamma-ray emission from the direction of the microquasar SS433 has been recently reported using five years of FermiLAT observations. The steady flux and a narrow spectral energy distribution peaking at 250 MeV suggest that gamma-rays could be rendered by the bulk jet kinetic power through proton-proton collisions at the SS433/W50 interaction regions. Here we report on the outcomes of the analysis of a larger Fermi-LAT data-set, using also the improved capabilities of the Pass 8 reprocessed data, which confirm and better characterize our previous results.
