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. We observe the only accepted target in our program (SDSS J1326-0005) with WFC3-IR and the F160W filter which, for the redshift of our target (z~3.3), covers the region of the 4000A break. The requested exposure time is one orbit. We will perform a four point box dither pattern and use SPARS sampling. The target is a point source (a quasar) and the main goal of the observations is to detect its faint host galaxy. According to the ETC, this observation will allow us to reach a S/N~6 in a 3x3 box for a galaxy surface brightness of mAB=25. For the HST/ETC simulation we used the spectrum of a merging galaxy (Arp 220). This is sufficient to clearly observe the morphology of the galaxies hosting these quasars.
