The Deepest X-Ray View of High-Redshift Galaxies: Constraints on Low-Rate Black Hole Accretion

This article exploits the 7 Ms Chandra observations in the Chandra Deep Field-South (CDF-S), the deepest X-ray survey to date, coupled with CANDELS/GOODS-S data, to measure the total X-ray emission arising from 2076 galaxies at 3.5 ≤ z ≤ 6.5.
