Space-based gravitational-wave astronomy

基于空间的LISA(激光干涉仪空间天线)天文台将于本世纪30年代发射升空，它将为我们打开以毫赫频率观测引力波宇宙的能力。这将使我们能够直接观察两个星系合并期间的大质量黑洞的碰撞，恒星质量黑洞与星系中心超大质量黑洞的合并，以及我们银河系中的白矮星双星合并。分析LISA数据以观察这些来源将是一个具有挑战性的问题，最近成立了“LISA合作”来解决这些问题。在该项目中，目标是探索我们可以从LISA数据分析中学到什么。学生将有机会参加正在进行的LISA数据分析挑战，并开发观察和描述LISA将在其启动时观察到的来源类型的技术。

The space-based LISA (Laser Interferometer Space Antenna) observatory is due to launch in the2030s and will open our ability to observe the gravitational-wave Universe at millihertz frequencies.This will allow us to directly observe the collisions of massive black holes during the merger of twogalaxies, the merger of stellar-mass black holes with supermassive black holes in galactic centers andto observe white dwarf binary mergers in our Galaxy. Analysing LISA data to observe these sourceswill be a challenging problem and the "LISA collaboration" was recently formed to begin to addressthese problems.In the project the goals would be to explore what we can learn from the analysis of LISA data. Thestudent would be given the opportunity to participate in the ongoing LISA data-analysis challengesand develop techniques for observing and characterizing the types of sources that LISA will observewhen it launches.
