Abstract
We use isophote analysis performed on near-infrared images of matched samples of Seyfert and non-active galaxies to study the overall bar fractions, and properties of the bars. We conclude that there is a small but significant excess of bars among the host galaxies of Seyferts as compared to non-Seyfert control galaxies. Whereas 59% ± 9% of control galaxies are barred, 79% ± 8% of Seyfert hosts are barred. We also find that the bars in Seyfert galaxies are statistically less elliptical, thus “thicker” or “weaker”, than those in non-active galaxies. Implications for models of fuelling of AGN, as well as possible caveats in the interpretation of our results in that context, are briefly discussed.
