Relativistic Jets in SS443

The bizarre object SS433 is a binary system in which material for one component is being accreted onto a compact, massive companion. The accretion disk is so hot that matter and radiation are being expelled from its surface in powerful beams at velocities close to the speed of light. SS433 serves as a nearby example of the beaming of radiation by the strong gravitational field around a massive object also believed to power the distant quasars.
