|Title||Decoding disc-corona-jet variability in hard state black hole X-ray binaries|
|Author||Dr Phil Uttley|
|Description||We request 4 additional TOO EPIC-pn observations of the hard states of BHXRBs, to expand our highly successful campaign of triggering based on significant changes in characteristic timing signatures with respect to those seen in earlier hard state observations. Our campaign has already proven that an unstable disc drives the variability seen in hard states up to 1 Hz, and that the iron line becomes narrower as Lorentzian frequencies decrease. We will increase our coverage of the factor 100 variation in Lorentzian frequencies throughout the hard state, to more smoothly map the evolution of disc and power-law variability and the relationship to disc structure. We will use simultaneous fast optical timing from the ground, to measure the direct connection between disc and jet.|

|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.
