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 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 2004ApJ...600L..93G, Cat. II/261) in the Chandra
Deep Field-South (CDF-S) and the Hubble Deep Field-North (HDF-N).
