PDS 456, the most luminous nearby AGN, is now recognised as the prototype ultrafast outflow. Our recent XMM-Newton and NuSTAR campaign on PDS 456 establishedthe presence of a fast (0.3c), wide angle disk wind, sufficient to providesignificant mechanical feedback into its host galaxy. The new RGS data haverevealed the presence of variable, broad soft X-ray absorption lines from thedisk wind, which may be associated to the partial covering absorber. Here wepropose for 2x80 ks XMM-Newton observations of PDS 456 and a two orbit HST/COSsnapshot which will simultaneously measure the wind in the UV and X-rays. Therequested observations will be concurrent with a likely Astro-H observationduring 2016. For the first time we will obtain high resolution coverage of the wind from the UV to hard X-rays.

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.
