The z>4 Quasar Population Observed by Chandra and XMM-Newton

Astrophysics 2017-08-23 v1

Abstract

The current status of our Chandra and XMM-Newton project on high-redshift (z>4) quasars is briefly reviewed. We report the main results obtained in the last few years for the detected quasars, along with a few (~10%) intriguing cases where no detection has been obtained with Chandra snapshot observations.
