Abstract	Recent progress mapping AGN accretion disks reveals X-ray continuumreverberation from material at a few hundred Schwarzschild radii in NGC 4051. Wehave further demonstrated that claims of reverberation in 1H0707-495 fromultra-small radii, on the scale of the event horizon, are incorrect: like NGC4051, this AGN may be understood as exhibiting X-ray reverberation from materialfurther out. Ark 564 is known to exhibit large time delays when analyzed overlong timescales, and, like 1H0707-495, shows negative time lags on the fastestvariability timescales. We propose eight 55 ks observations of Ark 564 tothoroughly test the reverberation model, measure the transfer function and toderive strong constraints on the location and distribution of the X-ray reprocessor.

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.
