摘要
LCDM宇宙学为星系形成提供了一幅大体上有前景的图景,但难以与以下证据相调和:环境对椭圆星系和纯盘旋涡星系的演化所产生的惊人地微弱的影响。若在LCDM中加入一种具有演化质量的渐逝物质成分,以及足以促进近乎孤立的原星系早期组装的足够大的第五种力,可能有助于实现这种调和。我给出了一个简单的说明。

备注
At the referees' request I have enlarged the discussion of the phenomenological motivation for the model and the explanation of the physics. The model and the illustrations if its effects on structure formation are unchanged (apart from correction of a typo in the label Figure 4)
