Abstract:

The spectral energy distributions of galaxies from ultraviolet
to infrared wavelengths provide valuable information on the radiation
produced by stellar populations and the effects of gas and dust in
the interstellar medium on this radiation. Spectral interpretation
studies are therefore crucial to understand the formation and evolution
of galaxies. Observationally, combined ultraviolet, optical and infrared
data are now becoming available for large samples of galaxies. To extract
constraints on the stellar populations and interstellar medium of galaxies
from these observations requires the consistent modelling of the emission
by stars, gas and dust in galaxies. In this talk, I will present a simple
model to interpret consistently the multi-wavelength observations of large
samples of galaxies in terms of physical parameters. This model allows us
to obtain statistical constraints on the star formation histories and dust
contents of galaxies from a wide range of ultraviolet, optical and infrared
observations, and can be straightforwardly applied to interpret the spectral
energy distributions of any galaxy sample.
