Description Some of the most significant questions concerning the physics of black hole transients are addressed by studying BH binaries at low mass accretion rates. This is where radio observations indicate the presence of steady and powerful jets, and quiescence is where significant accretion energy may be advected across the BH event horizon. The recently launched NuSTAR mission will provide the first opportunity to probe this luminosity regime at >10 keV by observing the brightest quiescent system, V404 Cyg. We plan for coordinated radio coverage, and including XMM in this campaign is essential for: 1. constraining the shape of the broadband spectrum and the origin of the X-ray emission; 2. covering gaps in the light curve for the radio-X-ray study; and 3. for comparison to previous X-ray observations.

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.
