Abstract:
We present a Ks-selected catalog, dubbed FIREWORKS, for the Chandra
Deep Field-South (CDF-S) containing photometry in the U38, B435,
B, V, V606, R, i775, I, z850, J, H, Ks, [3.6um], [4.5um],
[5.8um], [8.0um], and MIPS [24um] bands. The imaging has a typical
Ktots,AB limit of 24.3mag (5σ) and coverage over
113arcmin2 in all bands and 138arcmin2 in all bands but H. We
cross-correlate our catalog with the 1Ms X-ray catalog by Giacconi et
al. (2002, Cat. J/ApJS/139/369) and with all available spectroscopic
redshifts to date. We find and explain systematic differences in a
comparison with the "z850+Ks"-selected GOODS-MUSIC catalog (Cat.
J/A+A/449/951) that covers ∼90% of the field. We exploit the
U38-to-24um photometry to determine which Ks-selected galaxies at
1.5<z<2.5 have the brightest total IR luminosities and which galaxies
contribute most to the integrated total IR emission. The answer to
both questions is that red galaxies are dominating in the IR. This is
true no matter whether color is defined in the rest-frame UV, optical,
or optical-near-IR. We do find, however, that among the reddest
galaxies in the rest-frame optical, there is a population of sources
with only little mid-IR emission, suggesting a quiescent nature.
Description:
Ground-based optical imaging of the Extended CDF-S with the Wide Field
Imager (WFI) on the ESO/MPG 2.2m telescope was obtained as part of the
COMBO-17 and ESO DPS surveys. During five epochs of observations, the
Advanced Camera for Surveys (ACS) on the Hubble Space Telescope (HST)
acquired imaging of the GOODS-South field. We use the ESO/GOODS data
release version 1.5 to complement the optical observations with NIR
imaging by the Very Large Telescope (VLT ISAAC fields). As a Spitzer
Space Telescope Legacy Program, superdeep images of the GOODS-South
field were taken with the Infrared Array Camera (IRAC) on board
Spitzer, over two epochs. The GOODS-South field was, finally, observed
at 24um with the Multiband Imaging Photometry for Spitzer (MIPS).

Note (1): Approximate total fluxes in other bandpasses can be computed by
F[band]t=F[band]xFKst/FKs), provided that there are no large
morphological k-corrections.
Note (2): measured within a 6" diameter circular aperture and then aperture
corrected (See section 4.2.2 for further details).
Note (3): In cases where the color aperture was the isophotal aperture
defined by the surface brightness threshold of
µ(Ks,AB)=24.6mag/arcsec2, aper is the diameter in arcseconds of
a circular aperture with equal area.
Note (4): When the isophotal or SExtractor's MAG_AUTO aperture was used,
this entry contains the equivalent circularized diameter corresponding
to that aperture.
Note (5): -99 when no cross identification within 2" was found. Note that
we accounted for the ∼1.3" systematic offset in the 1Ms catalog
(Giacconi et al., 2002, Cat. J/ApJS/139/369, <[GZW2002] XID NNN> in
Simbad), X-ray centroids, as pointed out before by Roche et al.,
2003MNRAS.346..803R 2003MNRAS.346..803R).
