|Title||X-ray and UV monitoring of the extraordinary changing-look AGN Mrk 1018|
|Author||Dr Mirko Krumpe|
|Description||We propose two quasi-simultaneous observations of XMM (each 65 ks) and HST (each 2 orbits) to understand the ongoing changes of changing-look AGN Mrk 1018. Optical monitoring revealed that the dramatic dimming phase stopped, suggesting that the accretion disk is in a major reconfiguration phase. The combined deep exposure will reveal which spectral components have changed since a high S-N XMM spectrum was taken during the bright phase a few years ago. Comparing the two AO17 observations will allow us to look for spectral changes on half-year timescales. These two XMM observations will fill the gaps of our already accepted low S-N Chandra monitoring program on Mrk 1018. The joint HST observations will allow us to establish the states of the accretion disk and how this connects to the X-ray corona.|

|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.
