Abstract | We propose up to 3 TOO EPIC-pn observations of the hard states of the BHXRBs CygX-1, GX 339-4 and SWIFT J1753.5-0127, to be triggered by a significant change intheir timing signatures with respect to those seen in earlier hard stateobservations. In this way, we will confirm or disprove the standard picture ofthe hard state where correlated timing and spectral properties are caused bytruncation of the accretion disk. We will use rms-spectra to disentangle theintrinsic and reprocessed contributions to disk thermal emission, and determinewhether the enhanced disk variability seen on longer time-scales is associatedwith the low-frequency Lorentzian in the PSD, which would for the first timeidentify this key timing signature with the disk. |

Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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. |
