本讲座探讨利用连续引力波与未来探测器进行多信使天文观测的可能性及科学意义。

摘要:

快速旋转中子星产生的连续引力波正处于引力波天文学的新前沿,并与电磁天文、核天文学和凝聚态物理有紧密联系。在本讲座中,我将回顾不同中子星群体中连续引力波检测的前景,特别是通过电磁观测加以辅助。尽管存在一些限制,当前的理论和观测表明,首次检测可能在几年内发生,而许多检测可能在下一代探测器时代,如宇宙探索者和爱因斯坦望远镜的时代发生。我还将回顾这些信号能带来哪些知识,每个信号都将包含比所有以往探测到的致密双星合并更多的周期。由于连续引力波发射机制依赖于中子星物理的某些方面,如地壳弹性,这些方面目前并未被天文观测和物理实验充分约束,因此它们的检测将为我们提供关于极端物质的新信息。通过结合引力波观测与平方千米阵列、下一代甚大阵、FAST和其他下一代电磁探测器的数据,还能学到更多。

英文摘要:

Continuous gravitational waves from rapidly rotating neutron stars are on the new frontiers of gravitational wave astrophysics and have strong connections to electromagnetic astronomy, nuclear astrophysics, and condensed matter physics. In this Colloquium I survey prospects for detection of continuous gravitational waves from various neutron star populations, especially aided by electromagnetic observations. Although there are caveats, current theories and observations suggest that the first detections are likely within a few years, and that many are likely in the era of next generation detectors such as Cosmic Explorer and the Einstein Telescope. I also survey what can be learned from these signals, each one of which will contain more cycles than all the compact binary mergers ever detected. Since continuous gravitational wave emission mechanisms depend on aspects of neutron star physics, such as crustal elasticity, which are not well constrained by current astronomical observations and physical experiments, their detection can tell us a great deal that is new about extreme matter. Even more can be learned by combining gravitational wave observations with data from the Square Kilometre Array, the Next Generation Very Large Array, FAST, and other electromagnetic detectors operating in the next generation era.
