论文摘要
在本文中，我们讨论了非线性磁带黑洞的光学特性，该黑洞被非零的宇宙常数$λ$包围。设置状态参数$ω= -3/2 $，我们研究了地平线，光子区域和该黑洞的阴影。事实证明，对于固定的典型参数$γ$，在一定范围内，旋转参数$ a $ a $和磁性电荷$ q $的增加，内部地平线半径增加，而外层半径降低。当$γ$或$λ$的普丝（$γ$）或$ a $ a $ a $ a $ a $ a $ a $ a $和$ q $时，宇宙范围$r_λ$减少。然后通过图形插图研究光子区域的形状并描绘。最后，我们讨论了典型的参数$γ$和宇宙常数$λ$对这个Balck孔具有固定观察者位置的阴影的影响。
In this paper,we discuss optical properties of the nonlinear magnetic charged black hole surrounded by quintessence with a non-zero cosmological constant $Λ$. Setting the state parameter $ω=-3/2$ , we studied the horizon, the photon region and the shadow of this black hole. It turned out that for a fixed quintessential parameter $γ$, in a certain range, with the increase of the rotation parameter $a$ and magnetic charge $Q$, the inner horizon radius increases while the outer horizon radius decreases. And the cosmological horizon $r_Λ$ decrease when $γ$ or $Λ$ incease and increase slightly with increasing $a$ and $Q$. The shapes of photon region were then studied and depicted through graphical illustrations. Finally, we discussed the effects of the quintessential parameter $γ$ and the cosmological constant $Λ$ on the shadow cast by this balck hole with a fixed observer position.
