Ultraluminous Infrared Galaxies
At luminosities above ~ 10 11 L ⊙ , infrared galaxies become the dominant population of extragalactic objects in the local Universe ( z < 0.5), being more numerous than optically selected starburst and Seyfert galaxies, and QSOs at comparable bolometric luminosity. At the highest luminosities, ul...
