Scientific paper

A 2D array of optical fibers generating simultaneous spectral and spatial information has been used to observe the central 13 arcsec of NGC 5728; on this basis, an analysis of the morphology and kinematics of the galaxy's circumstellar environment is conducted. The kinematic center coincides with the peak in radio emission, but is separated by about 1 arcsec from the maxima of the H-alpha and forbidden N II and S II emission. This strongly suggests that the active nucleus is obscured, and explains the nuclear redshift as well as the high ratio of circumnuclear-to-nuclear flux emission previously reported.
