论文摘要

在标量调整 - 矢量 - 重力(STVG)理论的旋转黑洞的时空(STVG)理论中,研究了同步器发出环的极化图像。黑洞拥有一个额外的无量纲MOG参数,描述了其与Kerr黑洞的偏差。 MOG参数对观察到的极化矢量和中风$ Q-U $环的影响在很大程度上取决于自旋参数,磁场构型,流体速度和观察倾斜角。对于固定的MOG参数,图像平面中极化矢量的变化与Kerr黑洞案例中的变化相似。 Kerr-Mog黑洞和M87*之间的极化图像的比较意味着STVG-MOG理论仍然存在一些可能性。

The polarized images of a synchrotron emitting ring are studied in the spacetime of a rotating black hole in the Scalar-Tensor-Vector-Gravity (STVG) theory. The black hole owns an additional dimensionless MOG parameter described its deviation from Kerr black hole. The effects of the MOG parameter on the observed polarization vector and Strokes $Q-U$ loops depend heavily on the spin parameter, the magnetic field configuration, the fluid velocity and the observation inclination angle. For the fixed MOG parameter, the changes of the polarization vector in the image plane are similar to those in the Kerr black hole case. The comparison of the polarization images between Kerr-MOG black hole and M87* implies that there remains some possibility for the STVG-MOG theory.
