| dc.description | A sample of 323 Ultraluminous IRAS galaxies (ULIRGs) has been correlated with the ROSAT All-Sky Survey and ROSAT public pointed observations. 22 objects are detected in ROSAT survey observations, and 6 ULIRGs are detected in addition in ROSAT public pointed observations. The detection is based on a visual inspection of the X-ray contour maps overlaid on optical images of ULIRGs taken from the Digitized Sky Survey. Simple power law fits were used to compute the absorption-corrected fluxes of the ROSAT detected ULIRGs. The ratio of the soft X-ray flux to the far-infrared luminosity is used to estimate the contribution from starburst and AGN emitting processes. These results are compared with the ISO SWS ULIRG diagnostic diagram. | |
