Poster Title: Stellar populations and their kinematics: mixed inversions of galaxy spectra
Abstract: I will present inversion techniques which aim at recovering the stellar content (age, metallicity, extinction) and kinematics of a stellar population from its observed absorption line spectrum. The originality of the mixed inversion technique is its potential to recover both stellar content and kinematics at the same time. These techniques use new synthetic high resolution spectra produced by PEGASE and minimization algorithms. The mixed inversions are safe enourgh to be applied to large ensembles of data, which could not be interpreted without such automated methods. I apply them to a subset of SDSS data and to mock data representing the bulge and disc population of the inner region of spiral galaxies
