The physical properties of the line emitting material in AGNs can be derived from well known line ratio diagnostics related to H-like and He-like ion transitions. Here, we show how to get this information (size, location and geometry of the emitting clouds) by a fit procedure of the overall observed spectrum with theoretical models developed by using the photoionization code CLOUDY.

Abstract
The physical properties of the line emitting material in AGNs can be derived from well known line ratio diagnostics related to H-like and He-like ion transitions. Here, we show how to get this information (size, location and geometry of the emitting clouds) by a fit procedure of the overall observed spectrum with theoretical models developed by using the photoionization code CLOUDY. Application to NGC 4051 in its low flux state is shown.File in questo prodotto:
