银河系引力波前景
The Galactic Gravitational wave foreground
摘要:
我提出了一个概述的银河双星,形成前景的欧空局/美国宇航局激光干涉仪空间天线(LISA)。目前已知的人口进行了讨论,以及当前和不久的将来,将发现新的系统的大规模调查。介绍了LISA数据可用时可以进行的天体物理学研究,特别注意核查双星、整个银河系的人口、中子星和黑洞双星以及球状星团中的源。我讨论了与电磁观测的协同作用,并纠正了与Nelemans(2006 a)相比,在光学中可以发现的LISA系统数量估计中的错误,并得出结论,至少有数百个系统应该是可检测的。
英文摘要:
I present an overview of the Galactic binaries that form the foreground for the ESA/NASA Laser Interferometer Space Antenna (LISA). The currently known population is discussed, as well as current and near-future large-scale surveys that will find new systems. The astrophysics that can be done when the LISA data becomes available is presented, with particular attention to verification binaries, the overall Galactic populations, neutron star and black hole binaries and sources in globular clusters. I discuss the synergy with electro-magnetic observations and correct an error in the estimate of the number of LISA systems that can be found in the optical compared to Nelemans (2006a) and conclude that at least several hundreds of systems should be detectable.
