    Accretion 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...

    Active 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...

    Adaptive 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...

    An 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...

    An 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...

    Are 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...

    Black hole-galaxy scaling relation evolution from Z̃2.5: Simulated observations with HARMONI on the ELT

    We present preliminary results on the potential of HARMONI, the first light integral field spectrograph for the ELT, to explore the evolution of central super...

    Completing the 3CR Chandra Snapshot Survey: Extragalactic Radio Sources at High Redshift

    We present the analysis of nine radio sources belonging to the Third Cambridge Revised catalog (3CR) observed with Chandra during Cycle 20 in the redshift range...

    Complex ionization structure and kinematics in the circumnuclear region of NGC 3227

    We present bidimensional spectroscopy of the circumnuclear region of the Seyfert galaxy NGC 3227. The physical and kinematical characteristics of the two...
