Are Boltzmann Plots of Hydrogen Balmer lines a tool for identifying a subclass of S1 AGN?
P. Rafanelli, S. Ciroi, V. Cracco +4
It is becoming clear that we can define two different types of nearby AGN belonging to the Seyfert 1 class (S1), on the basis of the match of the intensities of their Broad Balmer…
The Size of the Narrow-Line Emitting Region in the Seyfert 1 Galaxy NGC 5548 from Emission-Line Variability
B. M. Peterson, K. D. Denney, G. De Rosa +8
The narrow [O III] 4959, 5007 emission-line fluxes in the spectrum of the well-studied Seyfert 1 galaxy NGC 5548 are shown to vary with time. From this we show that the narrow line…
Spectral properties of the narrow-line region in Seyfert galaxies selected from the SDSS-DR7
L. Vaona, S. Ciroi, F. Di Mille +3
Although the properties of the narrow-line region (NLR) of active galactic nuclei(AGN) have been deeply studied by many authors in the past three decades, many questions are still…
The Relation between Nuclear Activity and Stellar Mass in Galaxies
G. La Mura, D. Bindoni, S. Ciroi +4
The existence of correlations between nuclear properties of galaxies, such as the mass of their central black holes, and larger scale features, like the bulge mass and luminosity,…
Distribution of the heavy elements throughout the extended narrow line region of the Seyfert galaxy NGC 7212
M. Contini, V. Cracco, S. Ciroi +1
The latest observations of line and continuum spectra emitted from the extended narrow line region (ENLR) of the Seyfert 2 galaxy NGC 7212 are analysed using models accounting for…
The analysis of the hydrogen broad Balmer line ratios: possible implications to the physical properties of the BLR of AGN
D. Ilic, L. C. Popovic, G. La Mura +2
We analyze the ratios of the broad hydrogen Balmer emission lines (from Hαto Hε) in the context of estimating the physical conditions in the broad line region (BLR) of active galac…
