Abstract:
    We measure the obscured star formation in z~1 early-type galaxies.
    This constrains the influence of star formation on their
    optical/near-IR colors, which, we found, are redder than predicted by
    the model by Bruzual & Charlot (2003MNRAS.344.1000B). From deep ACS
    imaging we construct a sample of 95 morphologically selected
    early-type galaxies in the HDF-N and CDF-S with spectroscopic
    redshifts in the range 0.85<z<1.15. We measure their 24um fluxes
    from the deep GOODS MIPS imaging and derive the IR luminosities and
    star formation rates (SFRs).

Description:
    We select galaxies with spectroscopic redshifts and early-type
    morphologies from Hubble Space Telescope Advanced Camera for Surveys
    (ACS) imaging from the Great Observatories Origin Deep Survey (GOODS;
    Giavalisco et al., 2004ApJ...600L..93G, Cat. <II/261>) in the Chandra
    Deep Field-South (CDF-S) and the Hubble Deep Field-North (HDF-N).
