We propose to continue the monitoring of the X-ray brightest Seyfert galaxy NGC4151 with integral, in order to measure its spectra as a function of the hardX-ray flux level. We will correlate the high energy spectral cutoff with othercontinuum parameters to determine the main physical mechanism driving thevariability. We will also disentangle the contributions to the reflection humpfrom close and distant reflectors, and correlate those with the narrow iron linevariability to determine the nature of the thick reprocessing medium and thegeometry of cold matter surrounding the source. We will finally probe for theexistence of a hard non-thermal tail. We request four observations of 200 kseach, for which we will propose four 10 ks accompanying XMM-Newton observations.

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.
