|Title||EXTREME REFLECTION IN THE COMPLEX NARROW LINE SEYFERT 1 AGN PG 1535+547|
|Author||Dr Dominc Walton|
|Description||Previous X-ray observations of the nearby "complex" NLS1 PG1535+547 show evidence for some of the strongest reflection from the accretion disk observed among local, Compton-thin AGN. The unusually high reflection fraction indicates an extreme accretion geometry in which the intrinsic continuum emission experiences strong gravitational light bending, resulting in a broadband X-ray spectrum dominated by reflection from the inner accretion disk. However, PG1535+547 has never been observed in the hard X-ray band. We request a coordinated broadband X-ray observation of this remarkable source with XMM-Newton and NuSTAR in order to robustly confirm the extreme reflection, and utilize the full potential of the latest reflection models to measure the BH spin and constrain the accretion geometry.|

|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.
