论文摘要
我们研究了负责观察到的银河旋转曲线和星系中可见物质分布的力量之间差异的力的熵性。来自Spitzer光度法和准确旋转曲线（SPARC）数据库的观察结果用于研究所提出的模型的充分性。与流行的暗物质NFW质量谱相比，使用Fokker-Planck方程的简单解决方案得出的混凝土模型用于拟合SPARC数据。我们还表明，所提出模型的参数与平坦速度的参数以及3.6 $ $ $ m $ m的星系样品的光度之间存在相关性。
We investigate the possible entropic nature of the force responsible for the discrepancy between the observed galactic rotation curves and those expected from the distribution of visible matter in the galaxy. Observations from the Spitzer Photometry and Accurate Rotation Curves (SPARC) data base are used to study the adequacy of the proposed models. A concrete model derived from a simple solution of the Fokker-Planck equation is used to fit SPARC data, resulting in strong agreement with observations compared to the popular dark matter NFW mass profile. We also show that correlations exist between a parameter of the proposed model and the flat velocity as well as the Luminosity at 3.6 $μ$m of the sample of galaxies.
