| Abstract | We propose to observe 1ES1615+061, the only Seyfert 1 galaxy, for which ASCAdata suggest that the - unusually intense (EW~590 eV) - K-alpha fluorescent ironline is emitted by a substantially ionized relativistic accretion disk. In thisscenario, the historically remarkably variable (about a factor of 30) soft X-rayemission is mainly governed by a change in the accretion rate. The goals of thisobservation are: a) to determine the iron line profile; b) to characterize forthe first time self-consistently the physical (temperature, ionizationstructure) and geometrical properties of the reprocessing matter. We request 40ks of pn exposure time. Time was already granted to us to observe 1ES1615+061during the AO2 as a priority C target, but the observation was not performed. |

| 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. |
