High-redshift AGNs and galaxies behind the lensing cluster Abell 2744
Abstract
Abell 2744 serves as a gravitational lens to the high-redshift universe in JWST observations. The UNCOVER survey reported the detection of nearly twenty z>9 galaxies behind this lensing cluster. Additionally, an unexpected new population of galaxies, referred to as "little red dots'' was discovered in the JWST data behind Abell 2744, at 3<z<9. Using deep Chandra X-ray observations, we followed up on these high-redshift galaxies and searched for X-ray emission associated with their central BHs.
