Seyfert galaxies are thought to be undergoing very violent processes. Does that mean they are still evolving?

A Seyfert galaxy is a galaxy that has an active nucleus. Most massive galaxies have a supermassive black hole at their center, which causes material to fall into an accretion disc. The material that falls into the disc is heated by friction and gravitational forces, causing it to emit radiation and eventually form an active galactic nucleus. Quasars and Seyfert galaxies are examples of galaxies that go through this process.

Seyfert galaxies are similar to ordinary galaxies in all respects, with the exception of being extremely bright and possessing an active nucleus; they undergo star formation and star death processes.

A galactic nucleus can become active if there is enough material in the vicinity of the supermassive black hole to power the process, or the galaxy can stop being a Seyfert galaxy once the material falling into the central supermassive black hole runs out.

Yes, Seyfert galaxies are considered to be undergoing very violent processes, often associated with the presence of an active galactic nucleus (AGN) fueled by a supermassive black hole at the galaxy's center. These violent processes can include accretion of matter onto the black hole, resulting in the emission of intense radiation across the electromagnetic spectrum. The ongoing activity suggests that Seyfert galaxies are still evolving dynamically.
