  • Extensive QSO surveys carried out by SDSS have provided a very large sample of quasars both at low and high redshift. For low z objects it is possible to investigate their host galaxies and environments using directly the SDSS imagesWe have undertaken an extensive multiwavelength study of the a sample of about 400 quasars at z < 0.5 in order to characterize their environments at various scale-lengths. For a subsample of these QSO we have complemented the SDSS images with spectroscopy of the quasars and their close companion galaxies. We report here the main results of this study.
