Abstract:
　 It is crucial to improve our understanding of "feedback" in the cosmic evolution and evaluate the impact of starburst and active nuclei driven outflows on galaxy evolution observationally. I will first briefly review recent progress in X-ray imaging of the "mini-starburst"---Galactic massive star forming regions, and then present the latest results from the CHandra survey of Extended Emission-line Regions in nearby Seyfert galaxies (CHEERS, PI: Wang), which offers a unique opportunity to examine feedback in action in much greater detail than at high redshift. In particular, findings in the circum-nuclear regions of nearby archetypal Seyfert galaxies and merging systems will be discussed in detail.
