Research output: Contribution to journalArticlepeer-review


We briefly review some of the progress made in the last decade in the study of the X-ray properties of the quasar population from the luminous, local objects observed by BeppoSAX to the large, rapidly increasing population of z > 4 quasars detected by Chandra and XMM-Newton in recent years.
