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, LCO′, are in the range 2-12×109 K km s−1 pc2 and inferred molecular gas masses, M(H2), are in the range 2-9×109 M⊙. 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.
