论文摘要
我们检查辐射及其对绕天体物理黑洞的积聚盘的影响。这些磁盘是热辐射的，可以在几何和光学上薄或厚。在该系列的第一篇论文中，我们讨论了本研究所需的物理和配方。随后，我们构建和解决相对论辐射传递方程，或在不可能的情况下找到合适的解决方案。我们继续介绍为这项工作考虑的一些积聚磁盘。然后，我们描述了开发的代码家族，以研究强力强的粒子轨迹，计算施加到磁盘材料上的辐射力，并生成无穷大的黑洞系统的观察图片。此外，我们还研究了工作的真实性和准确性。最后，我们研究了如何进一步使用结果来估计黑洞自旋和受这些辐射力的磁盘材料的运动。
We examine radiation and its effects on accretion disks orbiting astrophysical black holes. These disks are thermally radiating and can be geometrically and optically thin or thick. In this first paper of the series, we discuss the physics and the formulation required for this study. Subsequently, we construct and solve the relativistic radiative transfer equation, or find suitable solutions where that is not possible. We continue by presenting some of the accretion disks we considered for this work. We then describe the families of codes developed in order to study particle trajectories in strong gravity, calculate radiation forces exerted onto the disk material, and generate observation pictures of black hole systems at infinity. Furthermore, we also examine the veracity and accuracy of our work. Finally, we investigate how we can further use our results to estimate the black hole spin and the motion of disk material subjected to these radiation forces.
