Description There are over 400 very luminous (Lx virgul 1e38-1e40 erg/s) globular cluster X-ray
sources in nearby galaxies. None are present in our Galaxy, and their nature is
unknown. They may be accreting black holes, however, this is quite controversial
and it is contrary to theoretical expectations. The distance is too large to
make accurate studies of any of them that could reveal their nature. Luckily,
there is one such very luminous source, Bo375, in a globular cluster in M31. We
propose to perform ten 10 ksec observations of Bo375 and we expect that we will
be able to determine the nature of this object.

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.
