Previous X-ray observations of the nearby complex NLS1 PG1535+547 showevidence for some of the strongest reflection from the accretion disk observedamong local, Compton-thin AGN. The unusually high reflection fraction indicatesan extreme accretion geometry in which the intrinsic continuum emissionexperiences strong gravitational light bending, resulting in a broadband X-rayspectrum dominated by reflection from the inner accretion disk. However,PG1535+547 has never been observed in the hard X-ray band. We request acoordinated broadband X-ray observation of this remarkable source withXMM-Newton and NuSTAR in order to robustly confirm the extreme reflection, andutilize the full potential of the latest reflection models to measure the BH spin and constrain the accretion geometry.

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.
