Fe b 20 08 Understanding the relations between QSOs and their host galaxies from combined HST imaging and VLT spectroscopy 1


The host galaxies of six nearby QSOs are studied on the basis of high resolution HST optical images and spatially resolved VLT slit spectra. The gas ionization and velocity are mapped as a function of the distance to the central QSO. In the majority of the cases, the QSO significantly contributes to the gas ionization in its whole host galaxy, and sometimes… (More)
