Top panel: diffuse L_X(gas)/L_FIR, after only correcting for Galactic absorption, plotted vs. SFR. The data points are color-coded by merger stage. Merger stages 1 and 2 systems are marked as open green triangles. Merger stages 3, 4, and 5 are open cyan diamonds, and merger stages 6 and 7 are identified by blue open squares. Galaxies containing a Seyfert nucleus are circled in red. Black crosses mark the normal spirals from Mineo et al. (2012b). Middle panel: plot of diffuse L_X(gas)/SFR vs. SFR, where the X-ray is only corrected for Galactic absorption. Bottom panel: plot of diffuse L_X(gas)/SFR vs. SFR, after correction for internal absorption.
