While it is largely demonstrated that interaction can trigger activity, it is not yet possible to estabilish whether there is a one-to-one relation between activity and interaction. Indeed the results of the statistical studies that show an excess of physical companions among Seyfert galaxies are still controversial. In this poster we present our project of a systematic investigation of the global kinematical properties of a sample of nearby (z < 0.03) isolated active and non active galaxies aimed at unveiling features caused by past interactions. We show preliminary results about two active galaxies of our sample, NGC 6300 and Mrk 1157.

Abstract
While it is largely demonstrated that interaction can trigger activity, it is not yet possible to estabilish whether there is a one-to-one relation between activity and interaction. Indeed the results of the statistical studies that show an excess of physical companions among Seyfert galaxies are still controversial. In this poster we present our project of a systematic investigation of the global kinematical properties of a sample of nearby (z < 0.03) isolated active and non active galaxies aimed at unveiling features caused by past interactions. We show preliminary results about two active galaxies of our sample, NGC 6300 and Mrk 1157.
