We present long-slit observations of NGC 5128 in the range λλ3200-9800 Å, covering the nucleus and dust lane across the east-west direction, up to ≈2.2 kpc from the nucleus. The reddening-corrected continua and absorption features, when compared with those typical of a bulge stellar population, show that all locations within 1.8 kpc from the nucleus present a diluting continuum in the blue. We inv...
