The current paradigm for the co-evolution of galaxies and their supermassive black holes postulates that dust-obscured active galactic nuclei
(AGNs) represent a transitional phase towards a more luminous and unobscured state. However, our understanding of dusty AGNs and their
host galaxies at early cosmic times is inadequate due to observational limitations. Here, we present JWST observations of CID-931, an X-raydetected AGN at a spectroscopic redshift of zspec = 4.91. Multiband NIRCam imaging from the (...truncated)
