Description The defining property of a black hole is its event horizon through which matter and energy can rain in, but from which nothing can escape. We propose to establish the reality of event horizons by comparing in quiescent X-ray novae the behaviour of accreting black holes to the behaviour of accreting neutron stars. A by-product of this study will be a handle on the processes that transport angular momentum in accretion discs. Guided by earlier work and a new paradigm for accretion - the ADAF 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 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.
