论文摘要
我们研究了Schwarzschild黑洞的重力场中测试颗粒的运动，该黑洞被球形暗物质云包围，其切向压力非零，并计算了积聚磁盘的发光度。非消失的切向压力的存在可以模仿暗物质的角动量，同时仍考虑静态模型，从而简化了数学框架。我们比较了关于暗物质对静态超级黑洞振动磁盘光度的影响与先前研究的各向同性和各向异性压力的病例的数值结果。我们表明，在存在暗物质的情况下，积聚磁盘的通量和发光度与真空中的Schwarzschild黑洞不同，并突出了切向压力的影响。
We study the motion of test particles in the gravitational field of a Schwarzschild black hole surrounded by a spherical dark matter cloud with non-zero tangential pressure and compute the luminosity of the accretion disk. The presence of non vanishing tangential pressures allows to mimic the dark matter's angular momentum while still considering a static model, which simplifies the mathematical framework. We compare the numerical results about the influence of dark matter on the luminosity of accretion disks around static supermassive black holes with the previously studied cases of isotropic and anisotropic pressures. We show that the flux and luminosity of the accretion disk in the presence of dark matter are different from the case of a Schwarzschild black hole in vacuum and highlight the impact of the presence of tangential pressures.
