Relativistic Astrophysics and Gravitational Physics

耶鲁大学引力物理小组建议研究理论广义相对论和相对论天体物理学中的一些重要问题。特别是，Moncrief教授计划继续他对爱因斯坦方程大类解的奇点性质的研究。使用精确解析和高阶微扰技术，他希望最终能处理曲率奇异边界附近完全不对称的宇宙时空的一般情况，并对可能出现的不同类型的奇点进行分类。Moncrief还一直在研究假设的自引力宇宙弦的动力学性质，并提出了一种计算它们相互作用的数值方法。他还在继续开发一种微扰方法来处理天体物理上真实的旋转恒星核坍塌模型产生的引力辐射，并研究过度充电的可能性，从而违反宇宙审查猜想。

The Yale Gravitation Physics Group proposes to study a number of important problems in theoretical General Relativity and relativistic astrophysics. In particular Professor Moncrief plans to continue his investigations of the properties of singularities of large classes of solutions of Einstein's equations. Using both exact analytic and higher order perturbative techniques, he hopes eventually to treat the general case of completely non-symmetric cosmological spacetimes near their curvature singular boundaries and to classify the different types of singularities that may occur. Moncrief has also been studying the dynamical properties of hypothetical self- gravitating cosmic strings and has proposed a numerical method for computing their interactions. He is also continuing to develop a perturbational approach to treating the gravitational radiation produced by astrophysically realistic models of rotating stellar core collapse and studying the possibility of overcharging a magnetically (or dyonically) charged black hole and thereby violating the Cosmic Censorship Conjecture.
