Description We propose five 10 ksec observations of Cyg X-1. We will use the RGS to study
the orbital variations of the focused stellar wind of Cyg X-1 using absorption
edge and line measurements for the five random orbital phases of the
observations, and complement these with optical spectroscopy. By modifying the
low energy threshold of the EPIC-pn to 2.2keV, we are able to accomodate the
telemetry limitations of XMM and observe the source in the timing mode of EPIC
pn. This change allows us to obtain a very high signal to noise CCD-resolution
spectrum of Cyg X-1, to measure energy resolved power spectra, time lags, and
other timing quantities out to 100Hz, and interpret them with emission models
for black holes.

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.
