切伦科夫望远镜阵列（CTA）将成为未来十年及以后全球主要的超高能伽马射线天文学观测站。 CTA 的科学潜力极其广泛：从理解相对论宇宙粒子的作用到寻找暗物质。 CTA 是极端宇宙的探索者，在最大尺度上探索从黑洞附近到宇宙空洞的环境。 CTA 涵盖从 20 GeV 到 300 TeV 的广阔光子能量范围，将在所有方面改进当前仪器的性能。该天文台将在两个半球的地点运行阵列，以提供完整的天空覆盖，从而最大限度地发挥最罕见现象的潜力，例如非常接近的超新星、伽马射线爆发或引力波瞬变。南站有 99 个望远镜，北站有 19 个望远镜，可以灵活操作，并可以使用子阵列来执行特定任务。 CTA 将与许多新一代主要天文和天体粒子观测站产生重要的协同作用。将 CTA 数据与其他仪器的数据相结合的多波长和多信使方法将有助于更深入地了解目标源的宽带非热特性。 CTA 天文台将作为一个开放的、提案驱动的天文台进行运营，所有数据在预定的专有期限后都可在公共档案中获取。来自世界各地机构的科学家联合起来组成了 CTA 联盟。该联盟已准备了一份关于高度积极观察的核心计划的提案。该计划涵盖 CTA 运行前十年可用观测时间的约 40%，由本文件中介绍的各个关键科学项目 (KSP) 组成。
The Cherenkov Telescope Array, CTA, will be the major global observatory for very high energy gamma-ray astronomy over the next decade and beyond. The scientific potential of CTA is extremely broad: from understanding the role of relativistic cosmic particles to the search for dark matter. CTA is an explorer of the extreme universe, probing environments from the immediate neighbourhood of black holes to cosmic voids on the largest scales. Covering a huge range in photon energy from 20 GeV to 300 TeV, CTA will improve on all aspects of performance with respect to current instruments. The observatory will operate arrays on sites in both hemispheres to provide full sky coverage and will hence maximize the potential for the rarest phenomena such as very nearby supernovae, gamma-ray bursts or gravitational wave transients. With 99 telescopes on the southern site and 19 telescopes on the northern site, flexible operation will be possible, with sub-arrays available for specific tasks. CTA will have important synergies with many of the new generation of major astronomical and astroparticle observatories. Multi-wavelength and multi-messenger approaches combining CTA data with those from other instruments will lead to a deeper understanding of the broad-band non-thermal properties of target sources. The CTA Observatory will be operated as an open, proposal-driven observatory, with all data available on a public archive after a pre-defined proprietary period. Scientists from institutions worldwide have combined together to form the CTA Consortium. This Consortium has prepared a proposal for a Core Programme of highly motivated observations. The programme, encompassing approximately 40% of the available observing time over the first ten years of CTA operation, is made up of individual Key Science Projects (KSPs), which are presented in this document.
