Semi-empirical analysis of Sloan Digital Sky Survey galaxies–I. Spectral synthesis method
The study of stellar populations in galaxies is entering a new era with the availability of large
and high-quality data bases of both observed galactic spectra and state-of-the-art
evolutionary synthesis models. In this paper we investigate the power of spectral synthesis
as a means to estimate the physical properties of galaxies. Spectral synthesis is nothing
more than the decomposition of an observed spectrum in terms of a superposition of a base
of simple stellar populations of various ages and metallicities, producing as output the star …
