A physically based model of the ionizing radiation from active galaxies for photoionization modeling

Thomas, A. D; Groves, Brent; Sutherland, R. S; Dopita, M. A.; Kewley, Lisa; Jin, C.


We present a simplified model of active galactic nucleus (AGN) continuum emission designed for photoionization modeling. The new model OXAF reproduces the diversity of spectral shapes that arise in physically based models. We identify and explain degeneracies in the effects of AGN parameters on model spectral shapes, with a focus on the complete degeneracy between the black hole mass and AGN luminosity. Our reparametrized model OXAF removes these degeneracies and accepts three parameters...[Show more]
