Semi-empirical analysis of SDSS galaxies: I. Spectral synthesis method
R. Cid Fernandes, A. Mateus, L. Sodre +2
In this paper we investigate the power of spectral synthesis as a mean to estimate physical properties of galaxies. Spectral synthesis is nothing more than the decomposition of an…
The Stellar Populations of Low Luminosity Active Galactic Nuclei. III: Spatially Resolved Spectral Properties
R. Cid Fernandes, R. M. Gonzalez Delgado, T. Storchi-Bergmann +2
In a recent survey of the stellar populations of LINERS and LINER/HII Transition Objects (TOs) we identified a numerous class of nuclei which stand out because of their conspicuous…
Transition (LINER/HII) nuclei as evolved Composite (Seyfert 2/Starburst) nuclei
Thaisa Storchi-Bergmann, C. H. Brandt, R. Cid Fernandes +2
We compare the circumnuclear stellar population and environmental properies of Seyfert and Composite (Seyfert + Starburst) nuclei with those of LINERs and LINER/HII transition gala…
The star formation history of Seyfert 2 nuclei
R. Cid Fernandes, Q. Gu, J. Melnick +5
We present a study of the stellar populations in the central ~ 200 pc of a large and homogeneous sample comprising 79 nearby galaxies, most of which are type 2 Seyferts. The star-f…
Stellar Populations in Active Galaxies
Roberto Cid Fernandes
The role of stars and starbursts in AGN has been a recurring issue for nearly as long as AGN have been recognized as hosts of interesting phenomena. The heated ``starburst X monste…
Stellar Population in LLAGN.I: Ground-based observations
Roberto Cid Fernandes, Rosa M. Gonzalez Delgado, Henrique Schmitt +6
(Abridge): We present a spectroscopic study of the stellar populations of Low Luminosity AGN (LLAGN). Our main goal is to determine whether the stars who live in the innermost (100…
Stellar Population in LLAGN.II: STIS observations
Rosa M. Gonzalez Delgado, Roberto Cid Fernandes, Enrique Perez +5
We present a study of the stellar population in Low Luminosity AGN (LLAGN). Our goal is to search for spectroscopic signatures of young and intermediate age stars, and to investiga…
