标题： Gravitational Collapse of Gravitational Waves in 3D Numerical Relativity

摘要： 我们证明三维强非线性引力波的演化可以在数值相对论中进行跟踪，从而允许对基本和观测结果进行许多有趣的研究。 我们研究了时间对称、轴对称{\it 和}非轴对称布里尔波的演化，包括那些强度如此之大以至于在自身自引力作用下坍缩形成黑洞的波。 确定了形成黑洞的临界振幅。 将黑洞形成过程中发出的引力波与两个米斯纳黑洞正面碰撞过程中发出的引力波进行了比较。 显示英文摘要

摘要： We demonstrate that evolutions of three-dimensional, strongly non-linear gravitational waves can be followed in numerical relativity, hence allowing many interesting studies of both fundamental and observational consequences. We study the evolution of time-symmetric, axisymmetric {\it and} non-axisymmetric Brill waves, including waves so strong that they collapse to form black holes under their own self-gravity. The critical amplitude for black hole formation is determined. The gravitational waves emitted in the black hole formation process are compared to those emitted in the head-on collision of two Misner black holes.
