Properties of cold molecular gas in four type-1 active galaxies hosting outflows

Feedback from active galactic nuclei (AGN) has proven to be a critical ingredient in the current picture of galaxy assembly and growth. However, observational constraints on AGN-driven outflows face technical challenges and as a result, the cold molecular gas outflow properties of type-1 AGN are not well known. We present new IRAM NOrthern Extended Milimeter Array (NOEMA) observations of CO (1-0) in F07599+6508, Z11598$-$0112, F13342+3932, and PG1440+356, all nearby type-1 AGN and ultraluminous infrared galaxies (ULIRGs). We achieve spatial resolution of 1-3 arcsec corresponding to physical scales of 2–8~kpc and spectral resolution of 15-60 km s${}^{-1}$ which enables updated CO (1-0) redshifts and a detailed morphological view of the cold molecular gas in these sources. The CO (1-0) luminosities, $L_{CO}^{\mathrm{\prime }}$, are in the range 2-12$\times {10}^9$ K km s${}^{-1}$ pc${}^2$ and inferred molecular gas masses, $M$(H${}_2$), are in the range 2-9$\times {10}^9$ M${}_{\odot }$. The velocity fields and gas distributions do not unambiguously identify any of these sources as having outflows. However, Z11598$-$0112 has signs of infalling material and after the subtraction of a rotating disk model PG 1440+356 shows complex kinematics in the residuals that may indicate an outflow or warped disk.
