Description
The growth of supermassive black holes (SMBHs) over cosmic time is imprinted in their X-ray luminosity that is emitted from the inner central engine of active galactic nuclei (AGN). Observationally, X-rays from AGN can be probed both through deep and wide X-ray surveys, and also through the integrated emission that makes up the cosmic X-ray background (CXB). I will give an overview of our constraints on SMBH growth from X-ray and multiwavelength surveys and the CXB, focusing on the newest frontiers: AGN at the very dawn of black holes and galaxies (redshift 6 and higher) and AGN that are heavily buried by gas and dust. I will point toward the exciting potential of eROSITA, ART-XC, and future observatories in further uncovering the cosmic growth of SMBHs.
