Scientific paper

We present preliminary results from a study of the SEDs of a complete sample of 65 LIRGs from GOALS. The spectral shapes at λ > 10μm are similar, while the largest variations occur in the NIR (L1μm5μm/L&sun; ~ 1.0-0.01) and UV (L1μm0.12μm/L&sun; ~ 2.0-0.005). Using stellar population synthesis models to fit the UV-NIR continuum data, we derive stellar masses for the host galaxies of log (M*/M&sun;) ~ 10.2-11.4 with a mean of ~ 10.8.
