ADAPTIVE OPTICS IMAGING OF QUASAR HOSTS

摘要: We present the results of adaptive optics (OA) imaging twelve (z 15:0) themselves are used as reference for correction. The images, obtained under poor seeing conditions, have typical spatial resolution F W HM 0:3 arcsec before deconvolution. deconvolved H band image PG 1700+514 has a 0.16 and reveals wealth details on companion host galaxy. Comparison between Hubble Space Telescope CFHT images shows how powerful competitive ground-based AO can be. Close companions obvious signs interactions found in four objects. 2D three galaxies unambiguously reveal bars spiral arms. morphology other dicult to determine from 1D surface brightness proles, deeper needed, which could be with systems 10 m class telescopes. Analysis mock data that elliptical always recognized such, whereas disk hosts missed small scale lengths large QSO contributions.
