摘要：
We present near-infrared spectra of the nuclear disk in the nearby radio galaxy NGC 5128 (Centaurus A). On the basis of the observed strengths of the [S III] 0.9532 mu m and [Fe II] 1.2567 mu m lines, we classify NGC 5128 as a LINER. Modeling of the strengths of these and additional Lines suggests that the nuclear region is powered by shocks rather than by photoionization.
