Abstract
We discuss here the spectroscopic properties of the Seyfert 2 galaxy NGC 7130 (= IC 5135). Emission line regions were isolated and line ratios were measured and fitted with photoionization models; this allowed to discriminate between thermal and non thermal ionization in the circumnuclear regions. Massive star formation is likely to occur at projected distances from the nucleus >= 2 kpc: line profiles in these regions suggest the presence of outflows of gas due to stellar winds from hot massive stars.File in questo prodotto:
