Description Understanding black hole systems in their canonical hard state is a major goal
of high energy astrophysics. This state features a hard X-ray spectrum, a high
level of timing noise, and emission from a jet at radio, infrared, and perhaps
higher frequencies. Observations can constrain the theoretical models by
answering two questions: Does the inner edge of the accretion disk recede in the
hard state?; and how is the accretion geometry related to the presence of a jet?
Here, we propose to extend X-ray and radio studies of the hard state to low flux
levels in order to answer these questions.

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.
