论文摘要
光学SETI（寻找外星智能）可以探索非常快的时间域，尤其是在大型天空覆盖的情况下，为新发现提供了一个机会，可以补充多媒体和时域天体物理学。全景SETI实验（Panoseti）旨在通过使用两个数十个望远镜的组装来拒绝通过同时检测来拒绝微弱的信号，从而在广泛的视野中观察纳秒至第二持续时间的光瞬变。三个Panoseti望远镜连接到用于在纳秒级同步时钟的白色兔子时间网络，已在Lick天文台部署在两个地点，该站点被677米的距离分隔677米，以区分附近的光源（例如Cherenkov的光源，例如Cherenkov在地球大气层中的粒子阵雨）与大型富有源源不断的源头。与此部署并行，我们介绍了在四个12米的Veritas Gamma-ray望远镜和两个Panoseti望远镜的同时观察中获得的结果。我们报告了Panoseti对天体物理伽玛射线的首次检测，其中包括三个事件，其能量在$ \\厚度$ 15 $ 15 TEV和$ \ temsim $ 50 TEV之间。这些是由螃蟹星云发出的，并使用联合Veritas观测结果鉴定为伽马射线。
Optical SETI (Search for Extraterrestrial Intelligence) instruments that can explore the very fast time domain, especially with large sky coverage, offer an opportunity for new discoveries that can complement multimessenger and time domain astrophysics. The Panoramic SETI experiment (PANOSETI) aims to observe optical transients with nanosecond to second duration over a wide field-of-view ($\thicksim$2,500 sq.deg.) by using two assemblies of tens of telescopes to reject spurious signals by coincidence detection. Three PANOSETI telescopes, connected to a White Rabbit timing network used to synchronize clocks at the nanosecond level, have been deployed at Lick Observatory on two sites separated by a distance of 677 meters to distinguish nearby light sources (such as Cherenkov light from particle showers in the Earth's atmosphere) from astrophysical sources at large distances. In parallel to this deployment, we present results obtained during four nights of simultaneous observations with the four 12-meter VERITAS gamma-ray telescopes and two PANOSETI telescopes at the Fred Lawrence Whipple Observatory. We report PANOSETI's first detection of astrophysical gamma rays, comprising three events with energies in the range between $\thicksim$15 TeV and $\thicksim$50 TeV. These were emitted by the Crab Nebula, and identified as gamma rays using joint VERITAS observations.
