Abstract Here we propose to monitor the bright Seyfert galaxy NGC 4151 with XMM-Newtonvia 6 observations, each of 20 ks, performed in successive satellite orbits andcoordinated with a deep INTEGRAL observation. We will investigate the detailedshape of the X-ray to Gamma-ray continuum in NGC 4151, study the nature of thecomplex absorber and look for correlated variability in the X-ray andultraviolet bands. The proposed programme will confront many unansweredquestions relating to the current AGN paradigm.

Mission Description The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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.
