Near-Infrared Coronal Lines in Narrow-Line Seyfert 1 Galaxies
Alberto Rodriguez-Ardila, Sueli M. Viegas, Miriani G. Pastoriza +1
We report spectroscopic observations in the wavelength region 0.8-2.4 microns aimed at detecting near-infrared coronal lines in a sample of 5 narrow-line and 1 broad-line Seyfert 1…
The OI Line Emission in Active Galactic Nuclei Revisited
A. Rodriguez-Ardila, S. M. Viegas, M. G. Pastoriza +2
UV, visible, and near-infrared spectroscopy is used to study the transitions of neutral oxygen leading to the emission of broad OI 8446, 11287 and 1304 in Active Galactic…
The signature of high velocity gas in the spectra of NGC 4151
M. Contini, S. M. Viegas, M. A. Prieto
The multiwavelength emission spectrum and associated velocity field of the Seyfert prototype NGC 4151 is modeled. HST data has impressively revealed the existence of a large range…
