Abstract: Galaxies, the building blocks of the Universe, are gravitationally linked systems made up of baryonic (stars, gas, and dust) and dark matter. How they form and evolve is one of the most studied, yet not understood, topics in modern astrophysics. To unveil their formation and evolution, the analysis of the stars populating these systems has been proven a powerful tool as the different stages in the evolution of a galaxy are imprinted in its stellar content. In particular, this analysis up to the outer parts of the galaxies is essential. As in these faint regions gravity is lower and the dynamical time-scales longer, fossil records from the time of galaxy assembly and formation are retained. In this thesis we use high-quality, spectroscopic (CALIFA) and photometric (SDSS) data along with cosmological simulations (RaDES) to characterise the stellar content in spiral galaxies, paying special attention to their outer regions. We define a sample of 88 disc galaxies from the CALIFA survey, for which we study their light distribution and obtain their stellar age and metallicity radial profiles.
