Positive and negative feedback of AGN outflows in NGC 5728
  We present a spatially-resolved analysis of ionized and molecular gas in a
nearby Seyfert 2 galaxy NGC 5728, using the VLT/MUSE and ALMA data. We find
ionized gas outflows out to ~kpc scales, which encounter the star formation
ring at 1 kpc radius. The star formation rate of the encountering region is
significantly high (~1.8 M$_{\rm sol}/yr/kpc^2$) compared to other regions in
the ring. In contrast, the CO (2-1) emission is significantly weaker by a
factor of ~3.5, indicating very high star formation efficiency. These results
support the positive feedback scenario that the AGN-driven outflows compress
the ISM in the ring, enhancing the star formation activity. In addition, we
detect outflow regions outside of spiral arms, in which gas is likely to be
removed from the spiral arms and no clear sign of star formation is detected.
The overall impact of AGN outflows on the global star formation in NGC 5728 is
limited, suggesting the feedback of the low-luminosity AGN is insignificant.
