In da Cunha, Charlot & Elbaz (2008) we present a physically-motivated model for the spectral energy distributions (SEDs) of galaxies which enables us to:

1. •interpret the observed mid-infrared and far-infrared emission of galaxies consistently with the emission at ultraviolet, optical and near-infrared wavelengths;
   

2. •statistically constrain physical parameters related to the star formation and dust content of large samples of galaxies from ultraviolet, optical and infrared observations.
   

These models are publicly available as a user-friendly package - MAGPHYS: Multi-wavelength Analysis of Galaxy Physical properties.

New MAGPHYS HIGHZ extension available at www.iap.fr/magphys.
