X-rays from the High-Redshift Universe: The Chandra view

Abstract

The study of the X-ray properties of z>4 quasars has grown substantially over the last few years, mostly thanks to Chandra. Here we focus on (1) the average X-ray properties of an optically selected, luminous sample of nine z>4 Palomar Digital Sky Survey quasars recently observed by Chandra, and (2) the X-ray spectral properties of three z>4 AGNs in the Chandra Deep Field-North (CDF-N) using the 2 Ms exposure.
