Abstract: We investigate the link between optical obscuration and X-ray absorption in active galactic nuclei (AGN) by combining X-ray spectroscopy from 4XMM-DR11 with SDSS DR16Q spectroscopy. Bayesian X-ray spectral fits were obtained within the XMM2Athena project, and host-galaxy properties were derived via textsc{CIGALE} SED fitting. Our final sample comprises 241 X-ray AGN at $zarXiv:2603.11180v1 Announce Type: new
