Testing the Unified Model with an Infrared Selected Sample of Seyferts
H. R. Schmitt, J. S. Ulvestad, R. R. J. Antonucci +3
We present a series of statistical tests using homogeneous data and measurements for a sample of Seyfert galaxies. These galaxies were selected from mostly isotropic properties, th…
The Importance of Shocks in the Ionization of the Narrow Line Region of Seyferts
H. R. Schmitt, A. L. Kinney, J. B. Hutchings +2
We discuss the viability of shocks as the principal source of ionization for the Narrow Line Region of Seyfert galaxies. We present the preliminary results of [OIII]5007A and radio…
The Frequency of Active and Quiescent Galaxies with Companions: Implications for the Feeding of the Nucleus
Henrique R. Schmitt
We analyze the idea that nuclear activity, either AGN or star formation, can be triggered by interactions, studying the percentage of active, HII and quiescent galaxies with compan…
Diagnostics of composite starburst+Seyfert 2 nuclei: Hints on the starburst-AGN connection
Roberto Cid Fernandes, Tim Heckman, Henrique Schmitt +2
We present a simple population synthesis scheme which recognizes composite starburst+Seyfert 2 nuclei from a few easy-to-obtain optical measurements. Composite systems seem to evol…
Circumnuclear stellar population, morphology and environment of Seyfert 2 galaxies: an evolutionary scenario
T. Storchi-Bergmann, R. M Gonzalez Delgado, H. R. Schmitt +2
We investigate the relation between the characteristics of the circumnuclear stellar population and both the galaxy morphology and the presence of close companions for a sample of…
Testing the Unified Model with an Infrared Selected Sample of Seyfert Galaxies
H. R. Schmitt, R. R. J. Antonucci, J. S. Ulvestad +3
We present a series of statistical tests done to a sample of 29 Seyfert 1 and 59 Seyfert 2 galaxies selected from mostly isotropic properties, their far infrared fluxes and warm in…
