| Description | PDS456, the most luminous nearby quasar, is the prototype ultra fast outflow. With NuSTAR and XMM, we established the presence of a fast (0.3c), wide angle accretion disk wind, with sufficient power to provide significant mechanical feedback into its host galaxy. In a subsequent analysis of archival HST observations, we have found evidence for a fast, 0.3c UV counterpart of the wind, which may make PDS456 the fastest BALQSO known to date. We have now been approved a further 2x3 orbit HST/COS observations for 2018, to confirm the fast nature of the UV wind and its variability. Here, we request simultaneous X-ray coverage to be coordinated with HST, via 2x80 ks NuSTAR + XMM observations, which will reveal the wind structure and variability from the UV to hard X-rays. |

| 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. |
