| Description | In accreting black hole and neutron star binaries, QPOs and broad Fe emission lines are both thought to be incisive diagnostics of the inner disk, and can even be used to constrain black hole spin parameters. We have discovered a connection between Fe line strength and QPO phase in RXTE observations of GRS 1915+105. This connection clearly ties Fe lines to radii less than 100 Rschw, where relativistic skewing is inevitable. Moreover, for a known mass, the connection gives two measures of radius; over-constraining radii in this way will enable mapping of the inner disk and strong tests of accretion flow models and general relativistic effects. We request a 45 ksec TOO observation of GRS 1915+105 to study this connection at CCD resolution. |

| 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. |
