20 Nov 2010 | | Abstract: | We have used the diagnostic diagram that compares the ratio of emission lines
[NII]$lambda$6584/H$alpha$ with the equivalent width of [NII]$lambda$6584,
as proposed by Coziol et al. (1998), to determine the source of ionization of
SDSS NELGs that cannot be classified by standard diagnostic diagrams, because
the emission line [OIII]$lambda$5007, H$eta$, or both, are missing. We find
these galaxies to be consistent with low luminosity AGNs, suggesting that this
characteristic is the signature of the LLAGNs in the nearby Universe. | | Source: | arXiv, 1011.4595 | | Services: | Forum | Review | PDF | Favorites | |
