PublicaciónAccretion tori and cones of ionizing radiation in Seyfert galaxies
The photoionization of extended narrow-line regions in Seyfert galaxies by the radiation produced in a thick accretion disk is studied. The emission-line...

PublicaciónActive galactic nuclei and nuclear starbursts.
The Starburst model for radio-quiet Active Galactic Nuclei (AGN) postulates that the activity seen in most AGN is powered solely by young stars and compact...

PublicaciónAdaptive Optics Observations of Active Galactic Nuclei: Zooming into the Central Parsec Region
First results from the AGN-Heidelberg program aimed at resolving the central pc region of the closest Active Galactic Nuclei in the IR are presented. The core...

PublicaciónAn idealized model for dust accretion in active galactic nuclei
With an adequate supply of matter, the inward drifting of dust particles induced by the Poynting-Robertson effect can lead to the formation of a shell or disk...

PublicaciónAn optical fiber system to perform bidimensional spectroscopy
This article describes a fiber optic system contrived to perform spectral imaging of extended objects. It consists of two fiber bundles mounted simultaneously...

PublicaciónAre the extended narrow line regions in AGN photoionized by the emission from thick accretion disks?
We study the photoionization of the Extended Narrow Line Region (ENLR) using three anisotropic radiation fields: (1) a geometrically thick accretion disk; (2) a...

PublicaciónBASS. XXIX. The Near-infrared View of the Broad-line Region (BLR): The Effects of Obscuration in BLR Characterization
Virial black hole (BH) mass (M BH) determination directly involves knowing the broad-line region (BLR) clouds' velocity distribution, their distance from the...

PublicaciónBASS. XXV. DR2 Broad-line-based Black Hole Mass Estimates and Biases from Obscuration
We present measurements of broad emission lines and virial estimates of supermassive black hole masses (M BH) for a large sample of ultrahard X-ray-selected...
