Summary
A set of bright UV galaxies showing weak X-ray emission was selected from the Chandra Deep Field South (CDFS). Using photometric redshifts from the COMBO-17 survey and a combination of optical and UV colors, together with Spitzer infrared fluxes, we estimate the current star formation rate (SFR) of the selected galaxies. The SFR was used to estimate the X-ray luminosities, finding that the selected galaxies are indeed weak X-ray emitters. We discuss the extreme nature of the selected sources concluding that we are probably observing an early transient phase when most of the high mass X-ray binaries have not yet been formed.
