Title Mapping the Inner Accretion Disk Wind in the Quasar PDS 456

Author Dr James Reeves
Description PDS 456 is the most luminous nearby AGN, more typical of quasars at high redshift. A previous 40ks XMM-Newton (2001) observation revealed deep, highly ionised absorption at iron K and at 1 keV in the RGS spectrum. Subsequent Suzaku observations resolved the powerful ionised outflow, moving at 0.25c and revealed a direct response of the iron K absorption to a decrease in the ionising flux. We propose to monitor the remarkable spectral variability and outflow from PDS 456, through a series of 5x100ks XMM-Newton observations. From the timescale of the absorber variability we will probe the inner structure of the quasar wind, on scales of 10s-100s of Rg from the black hole and determine the intrinsic mechanism for the rapid variability in PDS 456.

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.
