TeVeS转动曲线与引力透镜的不相容性
Incompatibility of Rotation Curves with Gravitational Lensing for TeVeS
摘要：
我们约束的单参数类TeVeS模型测试的理论对旋转曲线和强引力透镜数据在银河系尺度上，在我们的形式主义完全保持相对论。我们分析的结果是--至少在其最简单的原始形式中，这是迄今为止文献中唯一研究的形式-- TeVeS被排除在外，因为在不包括显著的暗物质成分的情况下，模型不能一致地同时拟合两组数据。它还表明，基本的宇宙学模型的细节是不相关的，我们的分析，这涉及到星系尺度。恒星的初始质量函数的选择-这影响重子质量的估计-被发现不会改变我们的结论。
英文摘要：
We constrain the one-parameter class of TeVeS models by testing the theory against both rotation curve and strong gravitational lensing data on galactic scales, remaining fully relativistic in our formalism. The upshot of our analysis is that -- at least in its simplest original form, which is the only one studied in the literature so far -- TeVeS is ruled out, in the sense that the models cannot consistently fit simultaneously the two sets of data without including a significant dark matter component. It is also shown that the details of the underlying cosmological model are not relevant for our analysis, which pertains to galactic scales. The choice of the stellar Initial Mass Function -- which affects the estimates of baryonic mass -- is found not to change our conclusions.
