written by Lewis Carroll

Seyfert Galaxies – This is an example of spiral galaxies in which active nuclei take place. The name was given in honor of the American astronomer Carl Seifert (1911-1960). Seiftian galaxies have one distinctive feature – their bright, very compact (star-shaped) core with wide emission lines in the spectrum. About 1% of spiral galaxies are Seyfert galaxies.
