论文摘要

Schwarzschild-Couder望远镜(SCT)是针对Cherenkov望远镜阵列提出的望远镜概念。它采用双肌光学设计来删除$ 8^{\ circ} $视野上的二氧化畸变,并使用高密度的硅光电型相机(具有4个Arcmin的像素分辨率),以记录Cosmic Ray和Gamma-Ray启动粒子壳的Cherenkov发出的大气层的Cherenkov。在Fred Lawrence Whipple天文台上构建了由直径为9.7 m的主镜和具有1536像素的部分仪器摄像机组成的原型SCT(PSCT)。该望远镜于2019年1月成立,在整个2019年进行了调试。我们描述了与PSCT进行的首次观察活动,该活动于2020年1月和2月进行,并证明了蟹状星云的统计学意义的发现,以$8.6σ$为$8.6σ$。

The Schwarzschild-Couder Telescope (SCT) is a telescope concept proposed for the Cherenkov Telescope Array. It employs a dual-mirror optical design to remove comatic aberrations over an $8^{\circ}$ field of view, and a high-density silicon photomultiplier camera (with a pixel resolution of 4 arcmin) to record Cherenkov emission from cosmic ray and gamma-ray initiated particle cascades in the atmosphere. The prototype SCT (pSCT), comprising a 9.7 m diameter primary mirror and a partially instrumented camera with 1536 pixels, has been constructed at the Fred Lawrence Whipple Observatory. The telescope was inaugurated in January 2019, with commissioning continuing throughout 2019. We describe the first campaign of observations with the pSCT, conducted in January and February of 2020, and demonstrate the detection of gamma-ray emission from the Crab Nebula with a statistical significance of $8.6σ$.
