A Unique View of AGN-Driven Molecular Outflows: The Discovery of a Massive Galaxy Counterpart to a $z=2.4$ High-Metallicity Damped Lyman-$\alpha$ Absorber

We report the discovery of a massive $\log (M/M_{\odot })=10.74_{-0.16}^{+0.18}$ galaxy at the same redshift as a carbon-monoxide-bearing sub-damped Lyman $\alpha$ absorber (sub-DLA) seen i…
