完美豪猪：低频引力波天文学的理想网络
Perfect porcupines: ideal networks for low frequency gravitational wave astronomy
摘要：
完美豪猪是特殊配置的引力波探测器网络，在极限条件下，单个探测器和它们之间的距离相对于感兴趣的引力波长很短。它们具有美丽的特性，使它们成为理想的引力波望远镜。我会明确地介绍最重要的案例。对于单臂探测器网络（如“AGIS”\cite{Dimopoulos_et_al}），最小完美豪猪有6个探测器，沿着正二十面体的6个直径定向。对于双臂探测器网络（如等臂迈克耳孙干涉仪LIGO/VIRGO），最小的完美豪猪是某个5探测器配置。
英文摘要：
Perfect porcupines are specially-configured networks of gravitational wave detectors, in the limit that the individual detectors and the distances between them are short relative to the gravitational wavelengths of interest. They have beautiful properties which make them ideal gravitational wave telescopes. I present the most important cases explicitly. For a network of one-arm detectors (like "AGIS" \cite{Dimopoulos_et_al}), the minimal perfect porcupine has 6 detectors, oriented along the 6 diameters of a regular icosahedron. For a network of two-arm detectors (like the equal-arm Michelson interferometers LIGO/VIRGO) the minimal perfect porcupine is a certain 5 detector configuration.
