| Description | We are following up through multiwavelength observations the WISSH sample of hyperluminous MIR-selected Type 1 quasars at zvirgul2.5-3.5. In these objects we expect powerful quasar feedback and galaxy mergers to manifest themselves in full force. We are finding the WISSH quasars to exhibit a mixture of two populations with powerful winds in different gas phases (OIII or CIV). They also seem to show a dichotomy in their X-ray luminosities and UV/X-ray slope. We propose here XMM and HST observations of three WISSH quasars showing powerful OIII outflows in order to establish whether (i) they have higher X-ray-to-MIR and X-ray-to-UV luminosity ratios compared to the CIV-wind population and (ii) powerful quasars in the blow-out phase are linked to mergers. |

| 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. |
