| Abstract: |
I present preliminary results of a small survey of X-ray weak quasars performed with Chandra. These objects, which were selected cross-correlating an optical spectroscopic survey with the ROSAT WGACAT, are more than 10 times weaker in the soft X-rays than "normal" PG quasars. Chandra is able to distinguish whether these sources are intrinsically weak in the X-rays or obscured by gas along the line of sight. |
