The CDF-S is the deepest X-ray image available and will remain so for thenear future. We provide a spectroscopic (64.5%; 64% with spectralclassifications) and photometric redshift catalog for the full 7 Ms sample, butmuch of our analysis focuses on the central (off-axis angles <5.7') region,which contains a large, faint ALMA sample of 75 >4.5-sigma 850 micron sources.We measure the 850 micron fluxes at the X-ray positions using the ALMA images,where available, or an ultradeep SCUBA-2 map. We find that the full X-raysample produces ~10% of the 850 micron extragalactic background light. Weseparate the submillimeter detected X-ray sources into star-forming galaxiesand AGNs using a star formation rate (SFR) versus X-ray luminosity calibrationfor high SFR galaxies. We confirm this separation using the X-ray photonindices. We measure the X-ray fluxes at the accurate positions of the 75 ALMAsources and detect 70% at >3-sigma in either the 0.5-2 or 2-7 keV bands.However, many of these may produce both their X-ray and submillimeter emissionby star formation. Indeed, we find that only 20% of the ALMA sources haveintermediate X-ray luminosities (rest-frame 8-28 keV luminosities of10^42.5-10^44 erg/s), and none has a high X-ray luminosity (>10^44 erg/s).Conversely, after combining the CDF-S with the CDF-N, we find extreme starformation (SFR>300 solar masses per yr) in some intermediate X-ray luminositysources but not in any high X-ray luminosity sources. We argue that thequenching of star formation in the most luminous AGNs may be a consequence ofthe clearing of gas in these sources.
