论文摘要
我们研究了非本地重力框架中椭圆星系的速度分布。根据这种方法,有可能在没有暗物质假设的情况下恢复椭圆星系的基本平面。具体而言,我们比较了非本地重力上下文中循环速度的理论预测与来自大量观察到的椭圆星系样本的相应值。我们采用表面亮度,有效的半径和速度色散作为基本平面的结构参数。作为最终结果,可以证明非本地重力效应可以在椭圆星系中重现恒星动力学,并始终如一地观察数据。
We investigate the velocity distribution of elliptical galaxies in the framework of Non-local Gravity. According to this approach, it is possible to recover the fundamental plane of elliptical galaxies without the dark matter hypothesis. Specifically, we compare theoretical predictions for circular velocity in Non-local Gravity context with the corresponding values coming from a large sample of observed elliptical galaxies. We adopt the surface brightness, effective radius and velocity dispersion as structural parameters for the fundamental plane. As final result, it is possible to show that non-local gravity effects can reproduce the stellar dynamics in elliptical galaxies and fit consistently observational data.
