Dusty, Radiation Pressure Dominated Photoionization. I. Model Description, Structure And Grids

Abstract

We present the implementation of dusty, radiation pressure dominated photoionization models applicable to the Narrow Line Regions (NLRs) of Active Galactic Nuclei, using the \mapiii code. We give a grid of the predicted intensities of the most commonly used diagnostic spectral lines in the UV, optical and IR, covering a wide range of density, metallicity, the power-law index characterizing the photoionizing source and photoionization parameter, for use in the diagnosis of NLRs. We examine the temperature, density and ionization structure of these models, investigating the effect of variation of these parameters in order to gain a better understanding of NLR clouds themselves.
