Warmers: Massive Stars in the Nuclei of Galaxies
Published online by Cambridge University Press: 04 August 2017
Extract
A very small minority of all galaxies exhibit activity in their nuclear regions. The best known and most studied signature of nuclear activity is the presence of emission lines in the optical spectrum. In fact, active galaxies are classified as Seyferts, Liners or Starburst galaxies according to the strengths, widths and intensity ratios of their nuclear emission lines (figure 1).
