波动暗物质与塔利-费雪关系

Wave Dark Matter and the Tully-Fisher Relation

Hubert L. Bray, Andrew S. Goetz

摘要:

我们研究了一种称为波暗物质的暗物质理论,也被称为标量场暗物质(SFDM)和玻色子星暗物质或玻色-爱因斯坦凝聚体(BEC)暗物质,在球对称和它的关系到塔利-费舍尔关系。我们发现,固定波暗物质的振荡频率附近的暗星系晕的边缘意味着塔利-费舍尔的关系,这些晕。然后,我们描述了这个边界条件,这是大致相当于固定的每一个星系晕质量分布的指数衰减的尾巴的一半长度,可能会产生可检验的预测,这个理论的暗物质。

英文摘要:

We investigate a theory of dark matter called wave dark matter, also known as scalar field dark matter (SFDM) and boson star dark matter or Bose-Einstein condensate (BEC) dark matter, in spherical symmetry and its relation to the Tully-Fisher relation. We show that fixing the oscillation frequency of wave dark matter near the edge of dark galactic halos implies a Tully-Fisher-like relation for those halos. We then describe how this boundary condition, which is roughly equivalent to fixing the half-length of the exponentially decaying tail of each galactic halo mass profile, may yield testable predictions for this theory of dark matter.
