The signature of high velocity gas in the spectra of NGC 4151


The multiwavelength emission spectrum and associated velocity field of the Seyfert prototype NGC 4151 is modeled. NGC 4151 has been since the thirties subject of extensive modeling, nuclear photoionization being the basic approach considered by all authors. HST data has impressively revealed the existence of a large range of velocities (100-1500 km s −1… (More)
