论文摘要
在这项工作中，我们探讨了模糊暗物质（FDM）（或暗物质）对超质量黑洞（SMBH）的影响。这样的暗物质引入了孤子核心密度曲线，我们理想地将其视为围绕其中心位于其中心的SMBH的球形分布。在这个方向上，由于黑洞和暗物质时空几何形状的结合，我们获得了一个新的度量。我们将解决方案应用于两个已知的SMBH -SGR。 A*和M87*并使用EHT使用的阴影直径的经验数据来约束Soliton Core Radius $ r_ \ text {C} $给定的某些值的玻色子质量$ m_ \ text {b} $。然后，我们根据这些约束和相对于静态观察者检查阴影半径的行为。我们发现，在区域内感知到不同的阴影大小，$ r_ \ text {obs} <r_ \ text {c} $和$ r_ \ text {obs}> r_ \ text {c} $，偏差更大，值$ m_ \ text {b text {b} <10^10^{-22} <10^{ - 22} $ ev。关于阴影行为，我们还分析了孤子轮廓对薄磁盘的影响。孤子暗物质效应通过事件视野附近的不同光度表现出来。我们还分析了由于孤子效应而导致的弱挠度角和产生的爱因斯坦环。我们发现，对于SMBH附近的光源，其影响参数可与Soliton Core相当。我们的结果表明，使用银河系中心使用SMBH对孤子暗物质效应的实验检测。
In this work, we explored the effect of the fuzzy dark matter (FDM) (or wave dark matter) halo on a supermassive black hole (SMBH). Such a dark matter introduces a soliton core density profile, and we treat it ideally as a spherical distribution that surrounds the SMBH located at its center. In this direction, we obtained a new metric due to the union of the black hole and dark matter spacetime geometries. We applied the solution to the two known SMBH - Sgr. A* and M87* and used the empirical data for the shadow diameter by EHT to constrain the soliton core radius $r_\text{c}$ given some values of the boson mass $m_\text{b}$. Then, we examine the behavior of the shadow radius based on such constraints and relative to a static observer. We found that different shadow sizes are perceived at regions $r_\text{obs}<r_\text{c}$ and $r_\text{obs}>r_\text{c}$, and the deviation is greater for values $m_\text{b}<10^{-22}$ eV. Concerning the shadow behavior, we have also analyzed the effect of the soliton profile on the thin-accretion disk. Soliton dark matter effects manifest through the varying luminosity near the event horizon. We also analyzed the weak deflection angle and the produced Einstein rings due to soliton effects. We found considerable deviation, better than the shadow size deviation, for the light source near the SMBH with impact parameters comparable to the soliton core. Our results suggest the possible experimental detection of soliton dark matter effects using an SMBH at the galactic centers.
