摘要
我们呈现了来自南极望远镜Sunyaev Zel'dovich（SPT-SZ）巡天771平方度在95、150和220 GHz的点源星表。我们在至少一个波段中探测到1545个信噪比高于4.5 sigma的源。根据它们在巡天波段间的相对亮度，我们将这些源分为两类：一类以活动星系核的同步辐射为主，另一类以尘埃包裹的恒星形成星系的热辐射为主。我们发现了1238个同步辐射源和307个尘埃源。我们将所有源与外部星表进行交叉匹配，发现189个未识别的同步辐射源和189个未识别的尘埃源。没有对应体的尘埃源是高红移、强透镜亚毫米星系的好候选体。我们推导了每个族群从1 Jy到大约95 GHz的9 mJy、150 GHz的5 mJy和220 GHz的11 mJy的计数。我们将这些计数与星系族群模型进行比较，发现我们考虑的任何模型都不能很好地拟合所有三个波段的测量计数。这些差异意味着这些测量结果将成为下一代毫米波河外源族群模型的重要输入。
