| Abstract: |
Integral-field spectroscopy techniques are ideal to study objects of complex morphology and kinematics such as the circumnuclear region of AGN. We have obtained the stellar and ionized gas kinematics of four Seyfert galaxies by using integral field spectroscopy with optical fibers. For each galaxy, the kinematics of the stellar component can be well explained as rotation in a disk. The ionized gas is affected by radial motions along the radio axis path. In the cases of NGC 2992, NGC 4151, and NGC 4388 the deviation of the ionized gas kinematics relative to the stellar velocity field can be well explained purely by the presence of the active nucleus. For NGC 1068, a minor merger seems to be compatible withcomplex kinematics of the stellar and ionized gas components. |
