| Description | We propose a 120 ks XMM observation of the extraordinary changing-look AGN Mrk 1018 to constrain the distance and details of the structure that produces the narrow Fe-line. In 2015 our team discovered this highly unique AGN in which we are witnessing the ongoing transition process. The response of the narrow Fe-line to the significant drop of the primary X-ray radiation (dimmed by factor 10) did not happen immediately. Even in January 2019 (last high S/N XMM observation) the line flux only dropped by a factor of 5. Thus, we still expect a significant evolution of the line. A joint short HST observation is also requested to maximize the scientific return of the XMM investment and to study the connection of the X-ray emitting corona and the UV accretion disk. |

| 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. |
