Scientific paper

In this work we compare two distinct techniques to estimate the star formation rate (SFR) in high redshift galaxies: mid-infrared emission and SED fitting analysis. We used the multiwavelength GOODS-MUSIC catalog to estimate the total infrared luminosity, which is a SFR indicator arising from dust reprocessed emission, and the star formation rate from the overall SED shape using the 14 bands photometry. We will apply the two methods to a couple of physical topics: the selection of a sample of quiescent galaxies at high redshift and the measure of the star formation rate.
