论文摘要
预计天体物理黑洞会被发光的吸积流所包围，这是对黑洞进行成像的必要成分。在本文中，我们研究了典型的暗能量对被静态/插入球形积聚流的海沃德黑洞的阴影图像的影响。我们发现，典型问题的状态参数对hayward黑洞的水平，光子球和冲击参数的影响。研究了观察到的阴影的特定强度，以及两个不同球面吸积流中少量黑孔的阴影和光子环亮度。我们还使用SGR A*和M87*的事件范围望远镜观测数据来限制Hayward黑洞的自由参数。最后，相比之下，与schwarzschild和Hayward Black Holes的典型黑孔的典范黑孔的结果我们发现，典型问题对黑洞阴影的影响要比规律性效应更为重要。
It is expected that the astrophysical black holes are surrounded by a luminous accretion flow that is a necessary ingredient for imaging a black hole. In this paper, we study the influence of quintessence dark energy on the shadow images of a Hayward black hole surrounded by the static/infalling spherical accretion flow. We find the effect of the state parameter of quintessence matter on the horizons, photon sphere and impact parameter of the quintessence Hayward black hole. The observed specific intensity of the shadow and also the shadow and photon ring luminosities of the quintessence Hayward black hole in two different spherically accretion flow are investigated. We also use the Event Horizon Telescope observational data of Sgr A* and M87* to constrain the free parameters of quintessence Hayward black hole. Finally, by comparison the results of quintessence Hayward black holes with quintessence Schwarzschild and Hayward black holes we find that the effect of quintessence matter on the black hole shadow is more significant than the regularity effect.
