The elliptical galaxy NGC 5044: Stellar population and ionized gas
M. G. Rickes, M. G. Pastoriza, Ch Bonatto
In this work we investigate the stellar population, metallicity distribution and ionized gas in the elliptical galaxy NGC 5044, using long-slit spectroscopy and a stellar populatio…
The elliptical galaxies NGC 1052 and NGC 7796: stellar populations and abundance alpha/Fe ratio
A. de C. Milone, M. G. Rickes, M. G. Pastoriza
Context: The spatial distribution of the stellar populations inside a spheroidal system and their kinematical properties supply important informations about the formation process.…
Molecular Hydrogen and [FeII] in Active Galactic Nuclei
Alberto Rodriguez-Ardila, Miriani G. Pastoriza, Sueli Viegas +2
(Abridge) Near-infrared spectroscopy is used to study the kinematics and excitation mechanisms of the H2 and [FeII] gas in a sample of AGN. The H2 lines are unresolved in all objec…
