|Title||The nature of persistent INTEGRAL sources in our Galaxy|
|Author||Dr Antony Bird|
|Description||Recent analysis of all INTEGRAL Galactic bulge observations performed so far has lead to the detection of a new population of persistent sources, which are characterised by their hard X-ray emission. In order to understand their properties, and more importantly distinguish between different models (obscured high mass systems or low luminosity LMXBs) follow-up observations in the soft X-ray regime are needed. By determining the absorption column, the presence of emission lines and variability on virgul1 hr timescales we will be able to distinguish between the proposed models, and constrain the evolution of these systems. We will also obtain improved positions for follow ups in other wave bands.|

|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.
