| Description | The rare active galactic nuclei (AGN) that are oriented toward us so that their accretion flow exhibits disk-like megamaser emission present a remarkable opportunity to study the geometry of the AGN obscurer on typically unresolvable parsec scales. Not only is their orientation highly constrained, but their black hole masses are well measured, which is otherwise difficult to achieve in obscured AGN. Their high obscuring columns allow us to directly detect and more robustly model the reprocessed X-ray spectra onto which features due to the geometry of the obscuring gas are imprinted. With a total of 256 ks of XMM-Newton and 310 ks of NuSTAR time, we propose to significantly expand the sample of nearby AGN for which obscurer geometry can be uniquely constrained using broadband X-ray data. |

| 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. |
