团队合作实现梦想：优化引力波对应物的多望远镜观测
Teamwork Makes the Dream Work: Optimizing Multi-Telescope Observations of Gravitational-Wave Counterparts
摘要：
引力波探测器网络的灵敏度不断提高，导致在Advanced LIGO和Advanced Virgo的第三次观测运行中，对紧凑型双星合并系统的探测速度加快。不仅事件发生率增加了，而且可以探测到现象的距离也增加了，导致搜索对应物所需的天空体积覆盖范围增加。此外，探测器的改进导致发现了更紧凑的涉及中子星的双星合并，振兴了专门的后续活动。虽然科学界为优化单台望远镜观测作出了重大努力，同时使用天气观测和星系定位方法，但对网络中的协调观测所作的努力较少。这一点变得至关重要，因为引力波天文学的出现引起了全球的兴趣，从而产生了大量的望远镜网络来寻找对应的望远镜。在本文中，我们扩展了一些技术开发的单个望远镜的望远镜网络。我们描述了这些算法的简单修改，并在现有的网络示例中演示它们。这些算法在开源软件\texttt{gwemopt}中实现，一些后续团队使用该软件，以便于更广泛的社区使用。
英文摘要：
The ever-increasing sensitivity of the network of gravitational-wave detectors has resulted in the accelerated rate of detections from compact binary coalescence systems in the third observing run of Advanced LIGO and Advanced Virgo. Not only has the event rate increased, but also the distances to which phenomena can be detected, leading to a rise in the required sky volume coverage to search for counterparts. Additionally, the improvement of the detectors has resulted in the discovery of more compact binary mergers involving neutron stars, revitalizing dedicated follow-up campaigns. While significant effort has been made by the community to optimize single telescope observations, using both synoptic and galaxy-targeting methods, less effort has been paid to coordinated observations in a network. This is becoming crucial, as the advent of gravitational-wave astronomy has garnered interest around the globe, resulting in abundant networks of telescopes available to search for counterparts. In this paper, we extend some of the techniques developed for single telescopes to a telescope network. We describe simple modifications to these algorithms and demonstrate them on existing network examples. These algorithms are implemented in the open-source software \texttt{gwemopt}, used by some follow-up teams, for ease of use by the broader community.
