对冷却流中 13 cD 星系的核进行了分光光度测定(波长 = 3400-5100 A)。其中 8 个物体存在光谱异常,包括异常强烈的禁止 O II 发射或过量通量效应。考虑了金属丰度效应、紫外线过量与冷却流形成的大质量 OB 星之间的关系,以及与吸积相关的低水平效应。 108 参考文献
Spectrophotometry (wavelength = 3400-5100 A) has been obtained for the nuclei of 13 cD galaxies in cooling flows. Spectral anomalies are found in 8 of the objects, consisting of abnormally strong forbidden O II emission or excess flux effects. Consideration is given to metallicity effects, the relationship between UV excesses and the presence of massive OB stars formed from the cooling flows, and low-level effects related to accretion. 108 refs.
