NuSTAR s unprecedented energy coverage has been providing many black hole spinmeasurements in AGN. Most of them are at the high end of black hole spin, wherestrong relativistic effects are present. In NGC 7314, the iron line shape fromspectroscopy and reverberation is narrow, suggesting a low black hole spin andpossibly either a truncated disk or an illuminating source that is distant fromthe disk. The current low energy data (< 10 keV) do not constrain the reflectionspectrum to specify this. Here, we propose to observe x for 100 ks with NuSTARand 60 ks with XMM in order to measure both the relativistic broadening andreverberation. The two will allow us to localize the X-ray source and test fortruncations. A truncated disk would have implications on accretion theory.

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.
