论文摘要
Bardeen提出了一种重力崩溃的磁性单极黑洞溶液，该解决方案没有奇异性。在本文中，我们研究了在存在完美的流体暗物质的情况下，旋转的Bardeen黑洞阴影的大小和形状。我们已经讨论了这样的旋转，磁单电荷和暗物质的影响的参数如何影响我们黑洞的阴影。通过使用两个可观察到的半径RS和失真参数R_S研究黑洞的表观形状。此外，还研究了黑洞的发射速率，我们发现，对于pfdm中的旋转bardeen，对于恒定的单极电荷，发射速率随着暗物质参数的增加而增加，发射速率随着磁电荷和自旋的增加而降低。
Bardeen proposed a gravitationally collapsing magnetic monopole black hole solution which is free of singularity. In this article, we have studied the size and shape of the rotating Bardeen blackhole shadow in presence of perfect fluid dark matter. we have discussed how the parameters such a spin, magnetic monopole charge and influence of dark matter affects the shadow of our blackhole. The apparent shape of the blackhole was studied by using two observables, the radius Rs and the distortion parameter R_s. Further the blackhole emission rate is also studied, we found out that for rotating Bardeen in PFDM ,For a constant monopole charge, the emission rate increases with increase in dark matter parameter, the emission rate decreases with increase in magnetic charge and spin.
