Physical Conditions in Low-Luminosity Active Galactic Nuclei

1984
Physical conditions in the nuclei of emission-line galaxies are investigated by analyzing their continua and optical emission lines. The strength and shape of the nonstellar continuum is derived for nine Seyfert galaxies. As in QSOs, it is described by a power law with slope ~ -1.1, and in the most luminous objects it flattens at blue and UV ...

Activity and Feeding in Nearby Low Luminosity Galactic Nuclei [PDF]

, 2014
Throughout the last decades a number of correlations between the proper- ties of the supermassive black holes (SMBH) in the center of galaxies and their hosting galaxies have been found. This suggests that these compo- nents influence each other in their evolution.

11.17. Radio emission from low-luminosity active galactic nuclei

Symposium - International Astronomical Union, 1998
“Low-luminosity” active galactic nuclei (LLAGNs) typically have ≳ mag, as opposed to −18 to −30 mag for luminous Seyfert 1 nuclei and QSOs. The physical origin of the class of emission-line nuclei known as low-ionization nuclear emission-line regions (LINERs; Heckman 1980) remains controversial.

The Luminosity Function of Quasars and Low Luminosity Active Galactic Nuclei

1986
The quasar luminosity function is extended to include the nuclear luminosities of Seyfert 1 galaxies. The model is fitted to the (total) luminosity data for the active galaxies from a complete flux-limited survey. A good fit is obtained with dN/dL∝L-1.2, matching onto the steeper quasar luminosity function near MB=-22.
