WISDOM project – XI. Star formation efficiency in the bulge of the AGN-host Galaxy NGC 3169 with SITELLE and ALMA

The star formation efficiency (SFE) has been shown to vary across different environments, particularly within galactic starbursts and deep the bulges of galaxies. Various quenching mechanisms may be responsible, ranging from dynamics feedback active nuclei (AGN). Here, we use spatially-resolved observations warm ionised gas emission lines imaging Fourier transform spectrograph SITELLE at Canada-France-Hawaii Telescope (CFHT) cold molecular (CO(2-1)) Atacama Large Millimeter/sub-millimeter Array (ALMA) study SFE in bulge AGN-host galaxy NGC 3169. After distinguishing star-forming regions AGN-ionised using emission-line ratio diagnostics, measure depletion times (\tau_dep = 1/SFE) with a spatial resolution \approx 100 pc galactocentric radius 1.8 kpc. We identify ring located radii 1.25 \pm 0.6 kpc an average \tau_dep 0.3 Gyr. At < 0.9 kpc, however, surface densities increase decreasing radius, latter reaching approximately 2.3 Gyr 500 pc. Based on analyses kinematics comparisons simulations, AGN feedback, morphology as possible causes radial profile observed central region
