Description GT-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. Proof of
the existence of event horizons is a foremost goal of astrophysics. However,
the goal is an extraordinary challenge since no photon can reach us from the
horizon. 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 A0620-00 and GRO J1655-40.

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.
