Semi-empirical analysis of SDSS galaxies: The SEAGal view

Natalia Vale Asari (UFSC, Florianopolis, Brazil), Grazyna Stasińska (LUTH, Observatoire de Paris)

The Sloan Digital Sky Survey (SDSS) obtained spectra of nearly a million of galaxies and organized them in a public database. Many groups of researchers analyzed those data with different techniques and (sometimes) different results. Here we present a selection of the results obtained by the STARLIGHT/SEAGal group, with emphasis on differences with other groups, especially as concerns the emission-line classification of galaxies. In particular, we will argue for the importance of the generally ignored class of retired galaxies.
