| Abstract: |
We present VESPA (VErsatile SPectral Analysis): a method which aims to recover the metallicity and star formation history of galaxies, given their spectrum. We use the full spectral range to find a solution constructed from synthetic models. Instead of working on a fixed set of age and metallicity bins, our parametrization is dynamic, and the number and the location of the parameters we recover from each galaxy is dictated by its noise properties and spectrum shape. The method is fast (around 5 seconds per galaxy), and the preliminary results are very encouraging. |
