Abstract

Abstract The non‐linear correlation between the UV and X‐ray emission observed in active galactic nuclei remains a puzzling question that challenges accretion models. While the UV emission originates from the cold disk, the X‐ray emission is emitted by a hot corona whose physical characteristics and geometry are still highly debated. The jet emitting disk‐standard accretion disk (JED‐SAD) is a spectral model stemming from self‐similar accretion‐ejection solutions. It is composed of an inner highly magnetized and hot accretion flow launching jets, the JED, and an outer SAD. The model has been successfully applied to X‐ray binaries outbursts. The AGN UV–X‐ray correlation represents another essential test for the JED‐SAD model. We use multiple AGN samples to explore the parameter space and identify the regions able to reproduce the observations. In this first paper, we show that the JED‐SAD model is able to reproduce the UV–X‐ray correlation.
