超大质量黑洞的LISA参数估计

LISA parameter estimation of supermassive black holes

Miquel Trias, Alicia M. Sintes

摘要:

利用后牛顿引力波形研究了$10^5-10^8\Ms$范围内超大质量黑洞的LISA参数估计,并与常用的限制后牛顿近似的结果进行了比较.分析表明,合并前的最后一年的观察,包括高次谐波明显改善了参数估计。我们特别注意的源定位误差,我们研究了改进的百分比,我们可以潜在地确定电磁同行的来源。我们还展示了额外的谐波如何有助于减轻任务期间失去激光链路的影响。

英文摘要:

We study parameter estimation of supermassive black holes in the range $10^5-10^8\Ms$ by LISA using the inspiral full post-Newtonian gravitational waveforms, and we compare the results with those arising from the commonly used restricted post-Newtonian approximation. The analysis shows that for observations of the last year before merger, the inclusion of the higher harmonics clearly improves the parameter estimation. We pay special attention to the source location errors and we study the improvement on the percentage of sources for which we could potentially identify electromagnetic counterparts. We also show how the additional harmonics can help to mitigate the impact of losing laser links during the mission.
