Title The hard state of a transient black hole: is the accretion disk truncated?

Description The combination of the fast EPIC-pn modes and broad-band coverage with RXTE proved to be an effective means of exploring accretion in bright Galactic black holes. XMM and NuSTAR provide an even more powerful combination. We propose to make one joint 40virgulks observation of a new or known black hole transient during a bright, hard outburst phase. The goals of this program are to 1) measure the spin of the black hole via the Fe K-alpha line and broad-band disk reflection spectrum, 2) test an apparent anti-correlation between winds and jets in soft and hard states by making a very sensitive search for winds in a hard, intermediate, or very high state. This observation will be supported by a network of ground-based observatories and X-ray monitoring.

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.
