We have obtained deep very Js, H, Ks imaging with the VLT on several fields with excellent optical imaging, in order to study high redshift galaxies. Using these Near-IR images, we identified a class of galaxies with Js - Ks color larger than 2.3. Photometric redshifts and spectroscopic follow-up showed that their mean redshift is 2.5 +- 0.7. These galaxies are complementary to Lyman break selected galaxies: the overlap is minimal, and the rest-frame optical colors of the J-K selected galaxies are much redder. Their contribution to the stellar mass density is comparable to that of Lyman breaks in our fields. We propose to obtain images of these galaxies with IRAF on Spitzer from 3.6 to 8 micron, covering our field around the cluster MS1054--03. This field is unique as it has the largest number of spectroscopically confirmed Js - Ks selected objects, and has several galaxies with rest frame optical spectroscopy. The Spitzer images will allow much improved photometric redshifts, SED modeling and mass estimates of these "red" galaxies, providing unique insight into their star formation history and evolutionary status. The deep Spitzer imaging will be one of the essential pieces to understand the link between these galaxies and "normal" Lyman break galaxies, and to obtain a comprehensive view of galaxy formation.
