用共形引力拟合矮星系自转曲线
Fitting dwarf galaxy rotation curves with conformal gravity
摘要：
我们继续研究共形引力理论在银河系自转曲线上的应用。在此之前，我们已经研究了111个不同的旋涡星系样本，包括高表面亮度星系，低表面亮度星系和矮星系。我们发现，在没有星系质光比以外的自由参数的情况下，该理论能够解释在整个星系旋转曲线组中观察到的系统学，而不需要任何暗物质。在本文中，我们扩展我们的研究，将进一步27个星系，其中25个是矮星系，并提供了3个额外的星系，已在原始样本的更新研究，并再次没有暗物质找到完全可以接受的适合，保存只有几个星系，我们发现有点麻烦。我们目前的研究带来了138的旋转曲线的星系，已占共形引力理论。由于该理论的主要成分之一是来自星系外部物质对星系运动的普遍贡献，因此独立于它们，我们的研究加强了共形引力研究的中心概念之一，即调用暗物质应被视为只不过是试图用纯粹的局部星系术语来描述全球物理学贡献。
英文摘要：
We continue our study of the application of the conformal gravity theory to galactic rotation curves. Previously we had studied a varied 111 spiral galaxy sample consisting of high surface brightness galaxies, low surface brightness galaxies and dwarf galaxies. With no free parameters other than galactic mass to light ratios, we had found that the theory is able to account for the systematics that is observed in the entire set of galactic rotation curves without the need for any dark matter whatsoever. In the present paper we extend our study to incorporate a further 27 galaxies of which 25 are dwarf galaxies and provide updated studies of 3 additional galaxies that had been in the original sample, and again without dark matter find fully acceptable fits, save only for just a few galaxies that we find to be somewhat troublesome. Our current study brings to 138 the number of rotation curves of galaxies that have been accounted for by the conformal gravity theory. Since one of the primary ingredients in the theory is a universal contribution to galactic motions coming from matter exterior to the galaxies, and thus independent of them, our study reinforces one of the central concepts of the conformal gravity studies, namely that invoking dark matter should be viewed as being nothing more than an attempt to describe global physics contributions in purely local galactic terms.
