Abstract

From 2-D spectroscopy of the [O III]  4959,5007 and [S III]  9069 lines we have studied the ionized gas-velocity field in the central regions of NGC 1068. The existence of a strong bipolar outflow of ionized gas is confirmed. The origin of this outflow, which is probably related to the active nucleus, is about 1.4″ NE of the optical nucleus; therefore, this region is a candidate to host the hidden nucleus of NGC 1068.
