论文摘要
最近发表的光谱完整的调查对2500 deg 2的南极望远镜（SPT）检测到的尘土形成星系的结果对星系组模型来说是充满挑战的，这些模型通常低估了观察到的大量高Z星系。在本文中，我们根据球形星系进化的物理接地模型来解释这些结果。该模型准确地重现了星系的红移分布，而无需调整参数。数据不支持通过对Herschel调查的一些分析报告的Z> 4个尘土星系的过量。
The results of the recently published spectroscopically complete survey of dusty star-forming galaxies detected by the South Pole Telescope (SPT) over 2500 deg^2 proved to be challenging for galaxy formation models that generally underpredict the observed abundance of high-z galaxies. In this paper we interpret these results in the light of a physically grounded model for the evolution of spheroidal galaxies. The model accurately reproduces the measured redshift distribution of galaxies without any adjustment of the parameters. The data do not support the indications of an excess of z > 4 dusty galaxies reported by some analyses of Herschel surveys.
