论文摘要
我们研究了重型物质和明显的暗物质对Verlinde紧急重力中黑洞阴影的影响。为此，我们考虑了不同的重质质量曲线和一个在黑洞周围径向自由落下的气体描述的光学薄盘区域。假设银河系中的大多数男性物质位于超大质量黑洞周围的银河系中心附近，我们使用两种模型的Baryonic物质模型来研究明显的暗物质对阴影和相应强度的影响。我们发现，周围物质对使用观测值的影响很小，但是，当周围的重重物质增加时，它变得很重要。为此，我们表明，简单幂定律在Verlinde理论中恒定重质质量的限制中的效果意味着明显的暗物质效应，这与具有等温暗物质谱的标准重力相似。我们还发现电磁通量辐射的强度取决于周围的质量。
We study the effect of baryonic matter and apparent dark matter on black hole shadow in Verlinde's Emergent Gravity. To do so, we consider different baryonic mass profiles and an optically-thin disk region described by a gas in a radial free fall around the black hole. Assuming that most of the baryonic matter in the galaxy is located near the galactic center surrounding a supermassive black hole, we use two models of power law mass profile for the baryonic matter to study the effect of apparent dark matter on the shadow and the corresponding intensity. We find that the effect of the surrounding matter on the shadow size using observational values is small, however, it becomes significant when the surrounding baryonic matter increases. To this end, we show that the effect of simple power law function in the limit of constant baryonic mass in Verlinde's theory implies an apparent dark matter effect which is similar to the standard gravity having an isothermal dark matter profile. We also find the intensity of the electromagnetic flux radiation depending on the surrounding mass.
