We fit the near-infrared to radio spectral energy distributions of 30 luminous and ultra-luminous infrared galaxies with pure starburst models or models that include both starburst and AGN components to determine important physical parameters for this population of objects. In particular we constrain the optical depth towards the luminosity source, the star formation rate, the star formation efficiency and the AGN fraction. ...

. Comment on J0431+2037 . A Gigahertz Peaked Spectrum (GPS) galaxy with complex radio structure on the scale of 10 to 100 mas (combined EVN+MERLIN data at 1.6 GHz, Dallacasa et al. 1995). Our image is consistent with the center-southern features of Dallacasa et al. (1995). The northern feature, ~180 mas N-NW from the field center, outside the boundary of the displayed image, can barely be seen in our data. VLBApls home page . Last modified: 16 Oct 2000
