Scientific paper

To establish the nature of X-ray-selected galaxies and to probe the potential contribution of starburst galaxies to the X-ray background, low-resolution 350-730-nm spectra have been obtained for the optical counterparts of 15 X-ray sources selected from the Einstein Observatory Extended Medium-Sensitivity Survey and Imaging Proportional Counter Source Catalog. At least three X-ray sources can be classified as starburst galaxies on the basis of line-ratio diagnostics alone. This is consistent with the number expected from recent models which predict that starburst galaxies could account for at least 15-20 percent of the extragalactic X-ray background at 2 keV.
