论文摘要
引力波（GW）为电磁频谱以外的宇宙打开了一个新窗口。自2015年以来，基于地面的GW探测器通过激光干扰法捕获了数十个GW事件。但是，所有地面探测器都是L形的米歇尔森干涉仪，对GW的方向反应非常有限。在这里，我们提出了一个常规三角金字塔形状的三维（3-D）激光干涉仪检测器，该探测器具有更大的球形对称天线模式。此外，新的配置对应于GW来源参数的更强限制，并且能够构建空式流程以摆脱信号般的噪声事件。这种类型的公里尺度的3-D检测器将为GW和电磁发射的关节搜索提供新的启示。
The gravitational wave (GW) has opened a new window to the universe beyond the electromagnetic spectrum. Since 2015, dozens of GW events have been caught by the ground-based GW detectors through laser interferometry. However, all the ground-based detectors are L-shaped Michelson interferometers, with very limited directional response to GW. Here we propose a three-dimensional (3-D) laser interferometer detector in the shape of a regular triangular pyramid, which has more spherically symmetric antenna pattern. Moreover, the new configuration corresponds to much stronger constraints on parameters of GW sources, and is capable of constructing null-streams to get rid of the signal-like noise events. A 3-D detector of kilometer scale of such kind would shed new light on the joint search of GW and electromagnetic emission.
