连续引力波研究的现状与展望
Status and perspectives of Continuous Gravitational Wave searches
摘要:
引力波天文学的诞生是由第一次探测到两个紧凑物体合并(也称为紧凑双星合并事件)产生的信号引发的。由先进干涉仪组成的地球网络所作的以下探测对许多科学领域产生了重大影响:天体物理学、宇宙学、核物理学和基础物理学。然而,致密的双星合并信号并不是LIGO、Virgo和KAGRA可能探测到的唯一类型的引力波。一个有趣的家庭仍然未被检测到的信号,在这篇评论中考虑的,是所谓的连续波,典型的例子是银河系,快速旋转的孤立中子星发射的引力辐射在其质量分布有一定程度的不对称性。在这项工作中,我将审查的地位和最新的结果,从先进的探测器数据分析,包括搜索暗物质签名。
英文摘要:
The birth of gravitational wave astronomy was triggered by the first detection of a signal produced by the merger of two compact objects (also known as a compact binary coalescence event). The following detections made by the Earth-based network of advanced interferometers had a significant impact in many fields of science: astrophysics, cosmology, nuclear physics and fundamental physics. However, compact binary coalescence signals are not the only type of gravitational waves potentially detectable by LIGO, Virgo, and KAGRA. An interesting family of still undetected signals, and the ones that are considered in this review, are the so-called continuous waves, paradigmatically exemplified by the gravitational radiation emitted by galactic, fast-spinning isolated neutron stars with a certain degree of asymmetry in their mass distribution. In this work, I will review the status and the latest results from the analyses of advanced detector data, including searches for dark matter signatures.
