The jet emitting disk standard accretion disk model applied to the active galactic nuclei ultra violet Xray correlation

Abstract

The non linear correlation between the UV and X-ray emission observed in Active Galactic Nuclei remains a puzzling question that challenged 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 represent 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 JED-SAD model is able to reproduce the UV--X-ray correlation.
