Title Disentangling the disks in hard state black hole X-ray binaries

Author Dr Phil Uttley
Description We propose up to 3 TOO EPIC-pn observations of the hard states of the BHXRBs Cyg X-1, GX 339-4 and SWIFT J1753.5-0127, to be triggered by a significant change in their timing signatures with respect to those seen in earlier hard state observations. In this way, we will confirm or disprove the standard picture of the hard state where correlated timing and spectral properties are caused by truncation of the accretion disk. We will use rms-spectra to disentangle the intrinsic and reprocessed contributions to disk thermal emission, and determine whether the enhanced disk variability seen on longer time-scales is associated with the low-frequency Lorentzian in the PSD, which would for the first time identify this key timing signature with the disk.

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.
