摘要

在这项工作中，我们研究了中微子自旋振荡在它们被厚厚的磁化吸积盘包围的旋转克尔黑洞引力散射的情况下。我们只考虑圆盘内部的环面磁场。微中子自旋进动是由微中子磁矩与盘内磁场的相互作用引起的。我们对观测到的中微子通量的自旋振荡的处理，是基于使用高性能并行计算对大量入射测试中微子传播的数值模拟。我们简要地讨论了我们的结果及其在天体物理中微子观测中的应用。

Neutrino Spin Oscillations near a Black Hole

In this work, we study neutrino spin oscillations in the case when they are gravitationally scattered off a rotating Kerr black hole surrounded by a thick magnetized accretion disk. We consider only toroidal magnetic field inside the disk. Neutrino spin precession is caused by the interaction of the neutrino magnetic moment with the magnetic field in the disk. Our treatment of spin oscillations of the observed neutrino fluxes, is based on numerical simulations of the propagation of a large number of incoming test neutrinos using High Performance Parallel Computing. We briefly discuss our results and their applications in the observations of astrophysical neutrinos.
