Obscuration and X-ray variability of active galactic nuclei
In this thesis I present a study of the properties of AGN populations based on X-ray surveys with ROSAT and Chandra. I have studied the short timescale X-ray variability properties of a sample of 156 radio-quiet quasars taken from the ROSAT PSPC archive covering a redshift range 0.1 < <i>z&...
