Flows and Shocks in Seyfert Galaxy Nuclei
A compilation of ultraviolet, optical, infrared, and radio data show that the Seyfert galaxies NGC 1275, NGC 3227, NGC 4151, NGC 5548, and NGC 7469 exhibit signs of flows or jets. Night-to-night variations in Balmer-line profiles and 10-150-day flares in the U BV RI bands resemble phenonema expected in shocks and flows.
