| Abstract: | The expected x-ray luminosity of megamaser OH galaxies lies between 22.5 and 24.5 erg s-1 Hz-1, with an average of 23.6 erg s-1 Hz-1. This range of luminosities is typical of galaxies with active nuclei and galaxies with active star formation. X-ray heating (

 10-22-10-18 erg s-1) and collisional pumping may be responsible for the maser emission in megamaser galaxies. |
