Can retired galaxies mimic active galaxies? Clues from the Sloan Digital Sky Survey
G. Stasinska, N. V. Asari, R. Cid Fernandes +5
The classification of galaxies as star forming or active is generally done in the ([O III]/Hbeta, [N II]/Halpha) plane. The Sloan Digital Sky Survey (SDSS) has revealed that, in th…
The Star Formation Histories of galaxies: A tour through the STARLIGHT-SDSS database
R. Cid Fernandes, W. Schoenell, J. M. Gomes +6
Retrieving the Star Formation History (SFH) of a galaxy out of its integrated spectrum is the central goal of stellar population synthesis. Recent advances in evolutionary synthesi…
Chemical abundances in six nearby star-forming regions: implications for galactic evolution and planet searches around very young stars
N. C. Santos, C. Melo, D. J. James +3
In this paper we present a study of chemical abundances in six star-forming regions. Stellar parameters and metallicities are derived using high-resolution, high S/N spectra of wea…
The history of star-forming galaxies in the Sloan Digital Sky Survey
N. V. Asari, R. Cid Fernandes, G. Stasinska +5
We study the evolution of 82302 star-forming (SF) galaxies from the SDSS. Our main goals are to explore new ways of handling star formation histories (SFH) obtained with our public…
Spectral Synthesis of SDSS Galaxies
L. Sodre, R. Cid Fernandes, A. Mateus +2
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 observed spect…
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…
