论文摘要
在目前的工作中，我们研究了通过积聚磁盘照明的Kerr-Melvin Black Hole（KMBH）的观察性外观。假定积聚盘位于赤道平面上，几何和光学上都薄。考虑到以下事实：在最内向稳定的圆轨道（ISCO）之外，积聚流动在进型或逆行的圆形轨道中移动，并且沿着ISCO内部跌落的轨道沿着地平线落在地平线上，我们开发了数值的向后射线追踪方法，并获得了伴随着攻击量的kmbh的图像，均与攻击式启动相处，以供各种黑孔旋转，并在各种启动下进行启动，并占据了启动的范围。我们在水平和纵向上介绍强度分布，并显示直接和镜头图像的红移的轮廓。我们的研究表明，内部阴影和临界曲线可用于估计黑洞周围的磁场而不会退化。
In this present work, we study the observational appearance of Kerr-Melvin black hole (KMBH) illuminated by an accretion disk. The accretion disk is assumed to be located on the equatorial plane and be thin both geometrically and optically. Considering the fact that outside the innermost stable circular orbit (ISCO) the accretion flow moves in prograde or retrograde circular orbit and falls towards the horizon along plunging orbit inside the ISCO, we develop the numerical backward ray-tracing method and obtain the images of KMBH accompanying with the accretion disk for various black hole spins, strengths of magnetic fields and inclination angles of observers. We present the intensity distribution horizontally and longitudinally and show the profiles of the red-shift for the direct and lensed images. Our study suggests that the inner shadow and critical curves can be used to estimate the magnetic field around a black hole without degeneration.
