摘要:

计算了具有线性动量的单个和二元黑洞的穿刺初始数据,求解了D维真空引力的约束方程。这些数据是通过修改arXiv:gr-qc/0404056中的伪谱代码生成的,并作为Cactus计算工具包中的TwoPunctures thorn提供。作为例子,我们展示了收敛图,违反哈密顿约束以及初始数据D= 4,5,6,7。这些初始数据是进行D维黑洞高能碰撞的起点。

英文摘要:

We calculate puncture initial data, corresponding to single and binary black holes with linear momenta, which solve the constraint equations of D dimensional vacuum gravity. The data are generated by a modification of the pseudo-spectral code presented in arXiv:gr-qc/0404056 and made available as the TwoPunctures thorn inside the Cactus computational toolkit. As examples, we exhibit convergence plots, the violation of the Hamiltonian constraint as well as the initial data for D=4,5,6,7. These initial data are the starting point to perform high energy collisions of black holes in D dimensions.
