带电旋转非对易黑洞的阴影

Shadow of a Charged Rotating Non-Commutative Black Hole

M. Sharif, Sehrish Iftikhar

摘要:

本文研究带电旋转非对易黑洞的阴影。为此,我们首先建立了零测地线,并研究了非对易电荷对光子轨道的影响。然后,我们探讨了自旋,倾斜角以及非对易电荷的阴影的轮廓的效果。结果表明,随着非对易电荷的减少,阴影的形状偏离圆形。我们还讨论了可观测量来研究黑洞投射的阴影中的变形和扭曲,这种变形和扭曲随着非对易电荷的小值而减小。最后,我们研究了等离子体存在下的阴影。我们得出结论,非对易性对黑洞阴影有很大的影响。

英文摘要:

This paper investigates the shadow of a charged rotating non-commutative black hole. For this purpose, we first formulate the null geodesics and study the effects of non-commutative charge on the photon orbit. We then explore the effect of spin, angle of inclination as well as non-commutative charge on the silhouette of the shadow. It is found that shape of the shadow deviates from the circle with the decrease in the non-commutative charge. We also discuss observable quantities to study the deformation and distortion in the shadow cast by the black hole which decreases for small values of non-commutative charge. Finally, we study the shadows in the presence of plasma. We conclude that the non-commutativity has a great impact on the black hole shadow.
