Description We propose four one-orbit observations of the AGN in NGCvirgul1365, with the main aim of measuring the spectral variations during an eclipse. This source showed extraordinary variability in the past observations, indicating a high probability of catching an eclipse by a Compton-thick cloud in the proposed observation time. The differences in the shape of the iron broad emission line at different phases of the eclipse would be a decisive proof of the relativistic effects on this line due to the strong gravity and fast orbital motion of the inner part of the accretion disc. In addition to this unique experiment, the spectral complexity of NGCvirgul1365 (with the highest S-N detection of iron absorption lines in AGNs) makes it the ideal target for a deep ..legacy. observation.

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.
