ISO-LWS spectroscopy of Centaurus A : extended star formation

Abstract

We present the first full FIR spectrum of Centaurus A (NGC 5128) from 43-196.7 µm. The data was obtained with the ISO Long Wavelength Spectrometer (LWS). We conclude that the FIR emission in a 70 beam centred on the nucleus is dominated by star formation rather than AGN activity. The flux in the far-infrared lines is ∼ 1% of the total FIR: the [C ii] line… (More)
