Description We propose a 130 ks observation of the bright narrow line Seyfert 1 galaxy Mrk 1044. We expect to perform variability analysis to discriminate among models for the soft X-ray emission. Mrk 1044 has a proven variability history. We aim at charaterizing its variability pattern throught the rms at different energies and the possible time lags between different X-ray energies at different frequency ranges. We will then use this pattern as diagnostic of the emission mechanism and geometry. Models considering disc emission, Compton scattering, smearing absorption or relativistically blurred reflection predict different values of the above properties that will be compared with the observations.

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.
