We present observations of the Ly-alpha galaxies at reshifts 4We present both our morphological analysis of these sources as well as our estimates of their masses, ages, and metalicities. The latter estimates are based on a thorough SED fitting of the broad band photometry that is available for these objects and using an extensive number of models. We have combined extremely deep HST/ACS, HST/NICMOS, VLT/ISAAC, and Spitzer/IRAC observations of these objects to provide us with a continuum rest-frame wavelength coverage ranging from the UV to the optical.
We observe that the color of these objects is extremely blue, and consistent with being dominated by a population of very young stars. The IRAC infrared observations, corresponding to the rest-frame optical, furthermore allow us to set upper limits on the amount of older stars present in these objects. We conclude that the Lyman-alpha emitters that we identified in the HUDF, and which should constitute a nearly complete sample between the redshifts of 4
