Description
We present a study of the relationship between large-scale environment and AGN activity across 0.5 ≤ z ≤ 5.0 in the GOODS-S field. This work combines two complementary JWST datasets in a two-layer approach: JADES DR5 serves as the environmental backbone, providing an exceptionally deep and wide photometric catalogue in the GOODS-S field from which local projected surface densities are estimated using the 10th-nearest-neighbour estimator (Dressler 1980). In conjunction with the JWST SMILES survey which contributes deep mid-infrared photometry that enables robust AGN-host decomposition through CIGALE SED fitting, in a regime where optical and near-infrared data alone are insufficient to disentangle AGN emission from stellar continuum at high redshift. Together, JADES DR5 anchors the large-scale structure context and SMILES identifies and characterizes the AGN population within it, allowing us to examine how AGN luminosity contribution and AGN number fraction vary as a function of local density across cosmic time. We will present the environmental dependence of AGN activity and discuss implications for environment-driven AGN triggering and quenching at high redshift.
