Title: FIREWORKS<i>U</i><sub>38</sub>–to–24 μm Photometry of the GOODS Chandra Deep Field–South: Multiwavelength Catalog and Total Infrared Properties of Distant<i>K</i><sub><i>s</i></sub>‐selected Galaxies
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, [3.6 μm], [4.5 μm], [5.8 μm], [8.0 μm], and MIPS [24 μm] bands. The imaging has a typical Ktots,AB limit of 24.3 mag (5 σ) and coverage over 113 arcmin2 in all bands and 138 arcmin2 in all bands but H. We cross-correlate our catalog with the 1 Ms X-ray catalog by Giacconi et al. (2002) 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 that covers ~90% of the field. We exploit the U38-to-24 μm 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.
