Description
The ongoing surveys of galaxies and those for the next generation of
telescopes will demand the execution of high-CPU consuming machine codes
for recovering detailed star formation histories (SFHs) and hence
age-metallicity relationships (AMRs). We present here an expeditive
method which provides quick-look AMRs on the basis of representative
ages and metallicities obtained from colour-magnitude diagram (CMD)
analyses. We have tested its performance by generating synthetic CMDs
for a wide variety of galaxy SFHs. The representative AMRs turn out to
be reliable down to a magnitude limit with a photometric completeness
factor higher than ∼85 per cent, and trace the chemical evolution
history for any stellar population (represented by a mean age and an
intrinsic age spread) with a total mass within ∼40 per cent of the
more massive stellar population in the galaxy.

The general aim of the project is to research the structure, evolutionary history and formation of galaxies through the study of their resolved stellar populations, both from photometry and spectroscopy. The group research concentrates in the most nearby objects, namely the Local Group galaxies including the Milky Way and M33 under the hypothesis
