We propose to obtain deep IRAC imaging of the most distant X-ray-luminous cluster of galaxies found to date. XMMU J2235.3-2557 was first detected as an extended XMM-Newton X-ray source and then spectroscopically confirmed at z=1.393 with the VLT-FORS2. Based on its high X-ray luminosity, ICM gas temperature, and optical/NIR richness, this galaxy cluster is very likely the most distant and most massive (z>1) structure yet identified. The proposed IRAC observations will measure the rest-frame near-IR flux of the z=1.4 cluster galaxies. This flux is known to be strongly correlated with the underlying stellar mass. We will construct the rest-frame near-IR luminosity function, derive the stellar mass function, and perform SED fitting to constrain galaxy ages and masses at the largest look-back times ever probed with clusters. With these diagnostics extracted from the high-density cluster environment, combined with complementary measures in the field population, we will directly test the predictions of competing models of galaxy formation.
