Description The Narrow-Line Seyfert 1 galaxy (NLS1) 1H 0707-495 exhibits a sharp spectral feature at energies around 7 keV. Both blurred ionised disc reflection and partial-covering can be used to explain the observed broad-band properties of 1H 0707-495, as both models reproduce very similar spectra in low-flux states. However, long term monitoring and a single deep observation will distinguish the correct, physically motivated AGN model, and permit us to probe the physics at work. We propose to examine 1H 0707-495 for 400 ks. A combination of monitoring (4 x 40 ks) and a deep pointing (1 x 240 ks) will be used.

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.
