模拟LISA数据挑战是一个展示LISA数据分析能力并鼓励其发展的项目。每一轮挑战包括一个或多个数据集，其中包含来自未公开参数来源的模拟仪器噪声和引力波。参与者分析数据集并报告源参数的最佳拟合解决方案。在这里，我们展示了2008年4月发布的第三个挑战的结果，它证明了从啁啾星系双星、旋转超大质量黑洞双星（最佳信噪比在10到2000之间）、同时极端质量比吸气（信噪比在10到50之间）、宇宙弦尖爆发（信噪比在10到100之间）和相对较大的各向同性背景(ω (gw)(f)类似于10(-11)，略低于LISA仪器噪声的信号的积极恢复。
The Mock LISA Data Challenges are a program to demonstrate LISA data-analysis capabilities and to encourage their development. Each round of challenges consists of one or more datasets containing simulated instrument noise and gravitational waves from sources of undisclosed parameters. Participants analyze the datasets and report best-fit solutions for the source parameters. Here we present the results of the third challenge, issued in April 2008, which demonstrated the positive recovery of signals from chirping galactic binaries, from spinning supermassive-black-hole binaries (with optimal SNRs between similar to 10 and 2000), from simultaneous extreme-mass-ratio inspirals (SNRs of 10-50), from cosmic-string-cusp bursts (SNRs of 10-100), and from a relatively loud isotropic background with Omega(gw)(f) similar to 10(-11), slightly below the LISA instrument noise.
