This award will support a theoretical program that will create complex general relativistic radiation-magnetohydrodynamic simulations to study black hole accretion flows. These flows will be modeled over a wide spatial scale from the immediate vicinity of the black hole to many hundred times the radius of the black hole. The project has several goals: (1) studying instabilities in the accretion disk, (2) exploring how strong radiation pressure alters the power and orientation of jets associated with black hole accretion, and (3) establishing the impact of radiation pressure in driving strong outflows.The contribute to the training of undergraduate students and to ongoing efforts to incorporate research results into the curriculum at the College of Charleston. The work is expected to have an impact on the study of black holes of a variety of masses, including those that drive active galactic nuclei.

该奖项将支持一项理论计划，该计划将创建复杂的广义相对论辐射磁流体动力学模拟，以研究黑洞吸积流。 这些流动将在从黑洞附近到黑洞半径数百倍的广泛空间尺度上进行建模。 该项目有几个目标：（1）研究吸积盘中的不稳定性，（2）探索强辐射压如何改变与黑洞吸积相关的喷流的功率和方向，（3）建立辐射压在驱动强外流中的影响。这些都有助于本科生的培训，并有助于将研究成果纳入查尔斯顿学院的课程。 这项工作预计将对各种质量的黑洞的研究产生影响，包括那些驱动活动星系核的黑洞。
