Scientific paper

We present the molecular gas distribution in the center of active galaxies NGC 4579, NGC 4826 and NGC 6951 obtained with the IRAM interferometer, with arcsecond resolution. Distortions m=2 and m=1 are dominant in those galaxies; computing the torques exerted on the gas by the stellar component (gravitational potential derived from the red images), we show how the gas is radially driven and confined into rings or pseudo-rings, and discuss how this can affect the feeding of AGN.
