An artist's impression of a relativistic jet propagating away from a black hole at close to the speed of light. Such jets are formed by the inner regions of the accretion flow: matter flowing inwards towards the black hole, via processes which are not yet fully understood. The accretion flow emits primarily in X-rays, the relativistic jet in the radio band: by combing observations in each band we can try and understand how such jets form and how much energy they carry away from the black hole.

Abstract:

In 1994 June-July we obtained nearly concurrent measurements of Cyg X-3 in hard X-rays and the infrared, using the OSSE instrument on GRO and the UKIRT. OSSE made a high significance measurement of the hard X-ray (> 50 keV) orbital light curve. Five days after the end of the OSSE observations we obtained a good IR /f-band light curve from data covering one orbit of Cyg X-3. Measurements of the light curve phase and shape probe the geometry of the system and the physics of radiation production and scattering. We determined for the first time that the light curve phases are consistent at these two different wavelengths. The light curve shapes were both marginally inconsistent (at about the 0.2% level) with the canonical soft X-ray shape measured by EXOSAT in 1983-1985. Underlying variations in DC IR flux and flaring during the observation make it difficult to draw unambiguous conclusions; more observations, with better IR coverage, are needed.
