Radio jets play an important role in quasar feedback , but direct observations showing how the jets interact with the multi-phase interstellar medium of galaxy disks are few and far between .
In this work , we provide new millimeter interferometric observations of PG 1700+518 in order to investigate the effect of its radio jet on the surrounding molecular gas .
PG 1700 is a radio-quiet , low-ionization broad absorption line quasar whose host galaxy has a nearby interacting companion .
On sub-kiloparsec scales , the ionized gas is driven to high velocities by a compact radio jet that is identified by radio interferometry .
We present observations from the NOrthern Extended Millimeter Array ( NOEMA ) interferometer with a 3 . ^ { \prime \prime } 8 ( 16 kpc ) synthesized beam where we detect the CO ( 1 \rightarrow 0 ) emission line at 30 \sigma significance with a total flux of 3.12 \pm 0.02 Jy km s ^ { -1 } and a typical velocity dispersion of 125 \pm 5 km s ^ { -1 } .
Despite the outflow in ionized gas , we find no concrete evidence that the CO gas is being affected by the radio jet on size scales of a kiloparsec or more .
However , a \sim 1 ^ { \prime \prime } drift in the spatial centroid of the CO emission as a function of velocity across the emission line and the compact nature of the jet hint that higher spatial resolution observations may reveal a signal of interaction between the jet and molecular gas .
