Abstract: We present a ≈20 ks Chandra ACIS-S observation of the strongly lensed ultraluminous infrared galaxy FSC 10214 + 4724. Although this observation achieves the equivalent sensitivity of an up to ≈4 Ms Chandra exposure (when corrected for gravitational lensing), the rest-frame 1.6–26.3 keV emission from FSC 10214 + 4724 is weak ( for a lensing boost of ≈100); a significant fraction of this X-ray emission appears to be due to vigorous star formation activity. If FSC 10214 + 4724 hosts a quasar, as previously suggested, then it must be obscured by Compton-thick material. We compare FSC 10214 + 4724 to high-redshift SCUBA galaxies and discuss the X-ray identification of Compton-thick AGNs at high redshift. [ABSTRACT FROM AUTHOR]
