摘要: ▪ Abstract At luminosities above 1011 , infrared galaxies become the dominant population of extragalactic objects in local Universe (z ≲ 0.3), being more numerous than optically selected starburst and Seyfert quasi-stellar at comparable bolometric luminosity. The trigger for intense emission appears to be strong interaction/merger molecular gas-rich spirals, bulk luminosity all but most luminous is due dust heating from an within giant clouds. At highest (Lir > 1012 ), nearly appear advanced mergers powered by a mixture circumnuclear active galactic nucleus energy sources, both which are fueled enormous concentration gas that has been funneled into merger nucleus. These ultraluminous may represent important stage formation powerful radio galaxies. They al...
