| Abstract | The defining property of a black hole is its event horizon through whichmatter and energy can rain in, but from which nothing can escape. Wepropose to establish the reality of event horizons by comparing inquiescent X-ray novae the behaviour of accreting black holes to thebehaviour of accreting neutron stars. A by-product of this study will bea handle on the processes that transport angular momentum in accretiondiscs. Guided by earlier work and a new paradigm for accretion - theADAF model - we propose to observe three black-hole systems, Nova Mus 1991, GRS 1009-45 and XTE J1550-564, with EPIC and the OM. |

| 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. |
