Description We propose a 360 ksec observation of the Seyfert Galaxy NGC 1365, a source having a unique set of properties, which make it the best suited target among X-ray absorbed AGNs to study the innermost region of AGNs: FeXXV and FeXXVI Kalpha and Kbeta absorption lines (the highest S-N detection so far among AGNs), rapidly varying cold absorber (N_H variations of virgul10^{23}cm^{-2} in a few hours, changes from Compton-thick to Compton-thin in two days), a relativistic iron emission line. This new long observation will constrain the dimensions of the absorbers, and, for the first time, allow the investigation of the dynamics and physical conditions of the hot absorber responsible of the iron absorption lines.

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.
