The mass growth in galaxies: CALIFA's perspective
Abstract
We report a few preliminary results from the analysis of the first 105 galaxies of the largest to date 3D spectroscopic survey of galaxies in the local universe (CALIFA). We apply the fossil record method of stellar population spectral synthesis by means of the STARLIGHT code to recover the spatially and time resolved star formation history of each galaxy. We describe the analysis pipeline we developed and some of its many products, that show the power of the combination of Integral Field Spectroscopy (IFS) data with spectral synthesis. As a preliminary result we show that, for massive galaxies, the inner parts of the galaxies grow faster than the outer ones, a clear signature of inside-out growth.
