最近，McGaugh，Lelli & Schombert根据Spitzer测光和精确旋转曲线的新数据，报道了在旋涡星系中观测到的总加速度和重子产生的加速度之间的紧密径向加速度关系。这种关系可以用不同的函数来拟合。然而，如果我们以晕加速关系的形式表示数据，则可以辨别这些函数。数据显示光晕加速度最大。我们研究了NFW（尖点）和Burkert（核心）配置文件的背景下，暗物质和不同的参数家庭的插值函数在修改后的牛顿动力学的框架。
Recently, from the new Spitzer Photometry and Accurate Rotation Curves data, McGaugh, Lelli & Schombert reported a tight radial acceleration relation between the observed total acceleration and the acceleration produced by baryons in spiral galaxies. The relation can be fitted by different functions. However, these functions can be discerned if we express the data in the form of a halo acceleration relation. The data reveals a maximum in the halo acceleration. We examined the NFW (cusp) and Burkert (core) profiles in the context of dark matter and different parameter families of the interpolating function in the framework of modified Newtonian dynamics.
