用外尔几何方法研究星系团的引力
Clusters of galaxies in a Weyl geometric approach to gravity
摘要：
基于Weyl几何标量引力张量理论（WST）和MOND近似，提出了一个星系团暗晕模型。它是由热气体和恒星的重子质量分布唯一确定的。第一个启发式检查对经验数据的19个集群（其中2个是离群值），从文献中，显示出令人鼓舞的结果。对不同背景理论（爱因斯坦引力加上$ΛCDM$与WST）的警告进行模化，17个星系团的离群简化系综中的15个的总质量似乎被正确预测（在重叠的$1\,σ$误差区间的意义上）。
英文摘要：
A model for the dark halos of galaxy clusters, based on the Weyl geometric scalar tensor theory of gravity (WST) with a MOND-like approximation, is proposed. It is uniquely determined by the baryonic mass distribution of hot gas and stars. A first heuristic check against empirical data for 19 clusters (2 of which are outliers), taken from the literature, shows encouraging results. Modulo a caveat resulting from different background theories (Einstein gravity plus $ΛCDM$ versus WST), the total mass for 15 of the outlier reduced ensemble of 17 clusters seems to be predicted correctly (in the sense of overlapping $1\,σ$ error intervals).
