Emission Line Luminosity Distributions of Seyfert 2 Galaxies
  We probed the relation between line activities of Seyfert 2 galaxies and
their host galaxies. We selected Seyfert 2 galaxies from the Sloan Digital Sky
Survey Data Release 10 with redshifts less 0.2. We used the luminosity of the
emission lines as indicators of AGN power. We found that the Seyfert 2 galaxies
seem to have two populations in the emission line luminosity distributions. We
considered the L[OIII]/Lbulge ratio as an accretion rate indicator and found
that the two Seyfert 2 distributions seem to have different accretion rates. We
found that these two Seyfert 2 populations, although classified by their
emission line distributions, turned out to have different morphology
distributions. These results indicate that these different populations of the
Seyfert 2 galaxies might be significantly different in their physical
conditions.
