Title Tracing accretion disk winds across the electromagnetic spectrum in BHXRBs

Description During their soft state edge-on black hole transients show blue-shifted absorption lines in their X-ray spectra due to hot and equatorial disk winds. Blue-shifted absorption lines have also been discovered in optical and ultraviolet(UV). These features must be produced in an outflow, but the physical conditions required to form them are very different. The three feautures have never been observed at the same time. It is unclear if they are linked to distinct outflows or simply with different regions. We propose to answer this question with simultaneous time-resolved spectroscopy of a high-inclination soft-state system in the X-ray, UV and optical bands. This will allow us to test if the three types of wind features are present simultaneously and whether they display correlated variability.

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations.
Since Earth's atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
