Gamma-rays from SS433: evidence for periodicity.

RASUL K., CHADWICK P.M., GRAHAM J.A. and BROWN A.M.

Abstract (from CDS):

In this paper we present our study of the gamma-ray emission from the microquasar SS433. Integrating over 9 yr of Fermi-LAT Pass 8 data, we detect SS433 with a significance of ∼13σ in the 200 to 500 MeV photon energy range, with evidence for an extension in the direction of the w1 X-ray 'hotspot'. A temporal analysis reveals evidence for modulation of SS433's gamma-ray emission with the precession period of its relativistic jet. This suggests that at least some of SS433's gamma-ray emission originates close to the object rather than from the jet termination regions.
