Previous X-ray observations of the Seyfert 2 galaxy IRAS00521 show evidence forsome of the strongest reflection from the accretion disk observed among local,Compton-thin AGN. The unusually high reflection fraction indicates an extremeaccretion geometry in which the intrinsic continuum emission experiences stronggravitational light bending, resulting in a broadband X-ray spectrum dominatedby reflection from the inner accretion disk. However, IRAS00521 has never beenobserved in the hard X-ray band. We request a coordinated broadband X-rayobservation of this remarkable source with XMM (175ks) and NuSTAR (300ks). Thequality of the data will enable us to robustly confirm the strong reflection,and utilize the full potential of the latest models to measure the black hole spin.

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.
