A Unique View of AGN-Driven Molecular Outflows: The Discovery of a Massive Galaxy Counterpart to a \$z=2.4\$ High-Metallicity Damped Lyman-\${\textbackslash}alpha\$ Absorber. Rudie, G. C., Newman, A. B., & Murphy, M. T. ArXiv e-prints, 1703:arXiv:1703.03807, March, 2017.
Paper abstract bibtex We report the discovery of massive \${\textbackslash}log(M/M_{\textbackslash}odot)=10.74{\textasciicircum}\{+0.18\}_\{-0.16\}\$ galaxy at the same redshift as a carbon-monoxide bearing sub-damped Lyman \${\textbackslash}alpha\$ absorber (sub-DLA) seen in the spectrum of the QSO J1439+1117. The galaxy, J1439B, is located 4.7" from the QSO sightline, a projected distance of 38 physical kpc at \$z=2.4189\$, and exhibits broad optical emission lines (\${\textbackslash}sigma_\{{\textbackslash}rm\{[O III]\}\}=303 {\textbackslash}pm 12\$ km s\${\textasciicircum}\{-1\}\$) with ratios characteristic of excitation by an active galactic nucleus (AGN). The galaxy has a factor of \${\textbackslash}sim\$10 lower star formation than is typical of star-forming galaxies of the same mass and redshift. The nearby DLA is highly enriched, suggesting its galactic counterpart must be massive if it follows the \$z{\textbackslash}sim2\$ mass-metallicity relationship. Metallic absorption associated with the DLA is spread over a velocity range \${\textbackslash}Delta v {\textgreater} 1000\$ km s\${\textasciicircum}\{-1\}\$, suggesting an energetic origin. We explore the possibility that a different galaxy could be responsible for the rare absorber, and conclude it is unlikely based on imaging, integral field spectroscopy, and high-\$z\$ massive galaxy pair statistics. We argue that the gas seen in absorption against the QSO was likely ejected from the galaxy J1439B and therefore provides a unique observational probe of AGN feedback in the distant universe.
