PublicationTesting the anisotropy of the central engine from extended emission line regions
Predictions about the angular behavior of the emission line spectrum from the ENLR for three plausible models of the nuclear engine are presented. Results are...

PublicationThe extended narrow line region of NGC 4151
We present high quality long-slit spectra of the extended narrow line region (ENLR) near the nucleus of NGC 4151. We have used these data to map the spatial...
