J/ApJ/661/L143      Star formation rate in Seyfert galaxies       (Wang+, 2007)

Suppressed star formation in circumnuclear regions in Seyfert galaxies. Wang J.-M., Chen Y.-M., Yan C.-S., Hu C., Bian W.-H. <Astrophys. J., 661, L143-L146 (2007)> =2007ApJ...661L.143W
ADC_Keywords: Active gal. nuclei ; Models, evolutionary Keywords: galaxies: active - galaxies: Seyfert - galaxies: starburst Abstract: Feedback from black hole activity is widely believed to play a key role in regulating star formation and black hole growth. A long-standing issue is the relation between star formation and the fueling of the supermassive black holes in active galactic nuclei (AGNs). We compile a sample of 57 Seyfert galaxies to tackle this issue. We estimate the surface densities of gas and star formation rates in circumnuclear regions (CNRs). Comparing them with the well-known Kennicutt-Schmidt (K-S) law, we find that the star formation rates (SFRs) in the CNRs of most Seyfert galaxies are suppressed in this sample. Feedback is suggested to explain the suppressed SFRs. File Summary:
