Low-Ionization Nuclear Emission Region
Low Ionization Nuclear Emitting Region

A Low Ionization Nuclear Emitting Region (LINER) represents a type of galactic nucleus that exhibits a characteristic emission spectrum. This spectrum is marked by weak emission lines from atoms that are in low ionization states, distinguishing it from other active galactic nuclei. LINERs are significant in the study of galaxy evolution and the interstellar medium, providing insights into the processes occurring in the central regions of galaxies.

LINERs are often associated with low-luminosity active galactic nuclei, where the energy output is considerably less than that of quasars or Seyfert galaxies. The presence of LINERs in a galaxy suggests a complex interplay between star formation, black hole activity, and the surrounding gas. Researchers utilize advanced telescopes and spectroscopy to analyze the light from these regions, unraveling the mysteries of their formation and the role they play in the cosmic ecosystem.
