Results of an analysis of SDSS galaxies in the VO

TL;DR

This paper presents a Virtual Observatory (VO) accessible database of analyzed SDSS galaxy spectra, including spectral fits, star formation histories, and emission line data, facilitating further research.

Contribution

It provides the first comprehensive VO-accessible database of SDSS galaxy spectral analysis results using STARLIGHT, integrating multiple spectral parameters.

Findings

Database includes original and synthetic spectra for each galaxy.

Provides star formation histories and emission line measurements.

Accessible through PGos3 by summer 2007.

Abstract

We present here the VO access to the results of an analysis of the spectra of Sloan Digital Sky Survey (SDSS) galaxies performed with the STARLIGHT code by Cid Fernandes et al. (2005). The results include for each galaxy the original SDSS spectrum, the best-fit synthetic spectrum, the star formation history, the pure emission line spectrum corrected from underlying stellar population (in SDSS emission line galaxies) and the intensity of several emission/absorption lines. The database will be accessible from the PGos3 at the end of summer 2007.
