Wind from the black-hole accretion disk driving a molecular outflow in an active galaxy
Veilleux, S.; Reynolds, C. S.; Tombesi, F. +3 more
Powerful winds driven by active galactic nuclei are often thought to affect the evolution of both supermassive black holes and their host galaxies, quenching star formation and explaining the close relationship between black holes and galaxies. Recent observations of large-scale molecular outflows in ultraluminous infrared galaxies support this qu…
Dense cloud cores revealed by CO in the low metallicity dwarf galaxy WLM
Brinks, Elias; Elmegreen, Bruce G.; Rubio, Monica +3 more
Understanding stellar birth requires observations of the clouds in which they form. These clouds are dense and self-gravitating, and in all existing observations they are molecular, with H2 the dominant species and carbon monoxide (CO) the best available tracer. When the abundances of carbon and oxygen are low compared with that of hydr…
