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…
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,…
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…
The origin of gas in the Extended Narrow Line Region of nearby Seyfert galaxies.I. NGC 7212
V. Cracco, S. Ciroi, F. Di Mille +6
The Extended Narrow Line Region (ENLR) of Active Galactic Nuclei (AGN) is a region of highly ionized gas with a size of few up to 15-20 kpc. When it shows a conical or bi-conical s…
The nature of gas and stars in the circumnuclear regions of AGN: a chemical approach
P. Rafanelli, L. Vaona, R. D'Abrusco +2
Aim of this communication is to describe the first results of a work-in-progress regarding the chemical properties of gas and stars in the circumnuclear regions of nearby galaxies.…
