Descripción
A grid of evolutionary synthesis models for different scenarios (initial
mass function slope, metallicity, age, etc.) and computing a set of
observables in a wavelength range extending from soft x-rays to radio is
reported. The model predictions were compared with observational data
for a sample of 13 star forming galaxies of different morphologies,
aiming to constrain the properties of the star formation episodes taking
place there. The most relevant results found are the following: the
slope of the IMF (Initial Mass Function) is not universal, varying in
the range 1 to 3 in starburst galaxies; there is no correlation between
IMF slope and metallicity of the environment in the sample; and the
interstellar absorption follows a law similar to the SMC one in regions
dominated by massive stars, independently on their metallicity.
