We present X-ray data for a complete sample of 44 luminous infrared galaxies(LIRGs), obtained with the Chandra X-ray Observatory. These are the X-rayobservations of the high luminosity portion of the Great Observatory All-skyLIRG Survey (GOALS), which includes the most luminous infrared selectedgalaxies, log (Lir/Lsun) > 11.73, in the local universe, z < 0.088. X-rays weredetected from 43 out of 44 objects, and their arcsec-resolution images,spectra, and radial brightness distributions are presented. With a selection byhard X-ray colour and the 6.4 keV iron line, AGN are found in 37% of theobjects, with higher luminosity sources more likely to contain an AGN. TheseAGN also tend to be found in late-stage mergers. The AGN fraction wouldincrease to 48% if objects with mid-IR [Ne V] detection are included. DoubleAGN are clearly detected only in NGC 6240 among 24 double/triple systems. OtherAGN are found either in single nucleus objects or in one of the double nucleiat similar rates. Objects without conventional X-ray signatures of AGN appearto be hard X-ray quiet, relative to the X-ray to far-IR correlation forstarburst galaxies, as discussed elsewhere. Most objects also show extendedsoft X-ray emission, which is likely related to an outflow from the nuclearregion, with a metal abundance pattern suggesting enrichment by core collapsesupernovae, as expected for a starburst.
