The CO(1-0) line emission is observed across ∼18 kpc scales with a resolution of ∼ 1 kpc. About 78 per cent of the CO(1-0) luminosity traces a galaxy-size rotating disc. However, after subtracting the emission due to such rotating disc, we detect with a S/N = 20 a residual emission in the central ∼4 kpc. Such residuals may trace a low velocity (v<SUB>LOS</SUB> = 170 km s<SUP>-1</SUP>) outflow. We compare the momentum rate (\dot{P}) and kinetic power (\dot{E}) of such putative molecular outflow with that of the X-ray UFO and find \dot{P}_{ mol}/\dot{P}_{ UFO}∼ 0.4 and \dot{E}_{ mol}/\dot{E}_{ UFO}∼ 4× 10^{-3}. This result is at odds with the energy-conserving scenario suggested by the large momentum boosts measured in some other molecular outflows. An alternative interpretation of the residual CO emission would be a compact rotating structure, distinct from the main disc, which would be a factor of ∼10-100 more extended and massive than typical circumnuclear discs revealed in Seyferts. In conclusion, in both scenarios, our results rule out the hypothesis of a momentum-boosted molecular outflow in this AGN, despite the presence of a powerful X-ray UFO.STAMPAenArticle10.1093/mnras/stz22492-s2.0-85073830065000489298100032https://academic.oup.com/mnras/article/489/2/1927/55495302019MNRAS.489.1927SFIS/05 - ASTRONOMIA E ASTROFISICAERC sectors::Physical Sciences and Engineering::PE9 Universe sciences: astro-physics/chemistry/biology; solar systems; stellar, galactic and extragalactic astronomy, planetary systems, cosmology, space science, instrumentation::PE9_6 Stars and stellar systems
