Matias M. Reynoso, Hugo R. Christiansen, Gustavo E. Romero
TL;DR
This paper investigates gamma-ray absorption mechanisms in SS433, highlighting how stellar and disk photon fields cause periodic absorption features affecting gamma-ray observations.
Contribution
It introduces a detailed analysis of gamma-ray opacity in SS433, emphasizing the role of the extended disk's UV photons in gamma-ray absorption.
Findings
Gamma-ray absorption varies periodically with star crossing events.
UV photons from the extended disk significantly contribute to gamma-ray opacity.
Absorption effects produce observable periodic signatures in gamma-ray data.
Abstract
We discuss the gamma-ray absorption in the inner region of the microquasar SS433. Our investigation includes several contributions to the opacity of this system. They result from the ambient fields generated by the primary star, possibly an A-type supergiant, and a very extended disk around the black hole. Besides the sharp and dramatic absorption effect that occurs every time the star crosses the emission zone, we find in the UV photon field from the extended disk an important source of absorption for very high energy gamma-rays. This results in periodic gamma-ray observational signatures.
