We are following up through multiwavelength observations the WISSH sample ofhyperluminous MIR-selected Type 1 quasars at zvirgul2.5-3.5. In these objects weexpect powerful quasar feedback and galaxy mergers to manifest themselves infull force. We are finding the WISSH quasars to exhibit a mixture of twopopulations with powerful winds in different gas phases (OIII or CIV). They alsoseem to show a dichotomy in their X-ray luminosities and UV/X-ray slope. Wepropose here XMM and HST observations of three WISSH quasars showing powerfulOIII outflows in order to establish whether (i) they have higher X-ray-to-MIRand 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 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.
