星系团巡天对新物理的敏感性和不敏感性
Sensitivity and Insensitivity of Galaxy Cluster Surveys to New Physics
摘要：
我们研究了星系团调查的影响和局限性的粒子物理学和引力的约束模型超越了标准模型。通量限制的星系团计数探测宇宙中大尺度结构形成的历史，并因此提供有用的宇宙学参数的约束。由于星团动力学某些方面的不确定性，星团巡天目前更适用于分析影响结构形成的物理学，而不是改变星团外观的物理学。作为一个例子，我们考虑的Lambda-CDM宇宙学和调光机制，如光子轴子混合。
英文摘要：
We study the implications and limitations of galaxy cluster surveys for constraining models of particle physics and gravity beyond the Standard Model. Flux limited cluster counts probe the history of large scale structure formation in the universe, and as such provide useful constraints on cosmological parameters. As a result of uncertainties in some aspects of cluster dynamics, cluster surveys are currently more useful for analyzing physics that would affect the formation of structure than physics that would modify the appearance of clusters. As an example we consider the Lambda-CDM cosmology and dimming mechanisms, such as photon-axion mixing.
