Wind-Fed Magnetic Flux and the Emergence of X-ray Coronae in Active Galactic Nuclei
This research investigates how circumnuclear stellar and supernova winds supply magnetic flux to a supermassive black hole, triggering the formation of radiatively efficient X-ray coronae. The study shows that this flux organizes into a magnetically dominated wedge, defining the corona's structure and saturation radius. This process suggests that AGN X-ray emergence depends critically on the coherence and topology of the ordered magnetic field supplied by the host environment.
