标题： Modeling Wave Dark Matter in Dwarf Spheroidal Galaxies

摘要： 本文研究了一种称为波暗物质（也称为标量场暗物质和玻色星）的暗物质模型，该模型最近也由于Bray[arXiv:1212.5745]提出的新几何视角而得到了新的激励。 波暗物质将暗物质描述为一个满足爱因斯坦-克莱因-戈登方程的标量场。 这些方程依赖于一个基本常数Upsilon（也称为克莱因-戈登方程的“质量项”）。 在本工作中，我们将波暗物质模型与观测结果进行比较，以获得Upsilon的一个工作值。 具体来说，我们将波暗物质的球对称静态态的质量分布与Burkert质量分布进行比较，Salucci等人[arXiv:1111.1165]已经表明，这种分布能够很好地预测八个经典矮椭球星系的速度弥散分布。 我们表明，波暗物质模型中的基本常数的一个合理工作值为Upsilon = 50 yr^{-1}。 我们还表明，在精确假设下，Upsilon的值可以被上限为1000 yr^{-1}。 显示英文摘要

摘要： This paper studies a model of dark matter called wave dark matter (also known as scalar field dark matter and boson stars) which has recently also been motivated by a new geometric perspective by Bray [arXiv:1212.5745]. Wave dark matter describes dark matter as a scalar field which satisfies the Einstein-Klein-Gordon equations. These equations rely on a fundamental constant Upsilon (also known as the "mass term" of the Klein-Gordon equation). In this work, we compare the wave dark matter model to observations to obtain a working value of Upsilon. Specifically, we compare the mass profiles of spherically symmetric static states of wave dark matter to the Burkert mass profiles that have been shown by Salucci et al. [arXiv:1111.1165] to predict well the velocity dispersion profiles of the eight classical dwarf spheroidal galaxies. We show that a reasonable working value for the fundamental constant in the wave dark matter model is Upsilon = 50 yr^{-1}. We also show that under precise assumptions the value of Upsilon can be bounded above by 1000 yr^{-1}.
