UV--NIR Restframe Luminosity Functions of the Galaxy Cluster EIS0048 at z~0.64

We derive the galaxy luminosity functions in V, R, I, and K bands of the cluster EIS 0048 at z~0.64 from data taken at the ESO Very Large Telescope. The data span the restframe wavelength range from UV, which is sensitive to even low rates of star formation, to the NIR, which maps the bulk of the stellar mass. By comparing our data and previous results with pure luminosity evolution models, we conclude that bright (M<= M^*+1) cluster galaxies are already assembled at z~1 and that star formation is almost completed at z~1.5.
