| Abstract | Recent studies of AGN data from deep X-ray surveys suggest that signatures ofreprocessing of the intrinsic X-ray continuum in the circumnuclear environmentgrow weaker with increasing luminosity, redshift, and line-of-sight columndensity. Selecting two bright and hard sources from a wide and deep X-raysurvey, we propose to directly measure the strength of reprocessing signaturesin individual high-luminosity AGN. Leveraging detailed studies of theirlower-luminosity local counterparts, we will directly and independently test thereported trends. The proposed joint XMM-Newton and NuSTAR observations offer aunique opportunity to advance studies of the obscuring circumnuclear material inAGN outside of the local Universe. |

| 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. |
