项目摘要

With the successful development of facilities for the detection of neutrinos and gravitational waves, as well as the deployment of next-generation gamma-ray detectors, the next decade will provide a wealth of opportunities for multi-messenger astronomy. The High Altitude Water Cherenkov (HAWC) gamma-ray observatory is an extremely successful survey instrument, and has inspired an ambitious Chinese effort, but that will also be sited in the northern hemisphere. This project will be carrying out the essential research and development needed for a next-generation ground-based survey instrument in the southern hemisphere: the Southern Wide-Field Gamma-Ray Observatory (SWGO). The work also contributes to maintaining US leadership in ground-based gamma-ray instruments. The team is committed to increasing the diversity and excellence of the STEM workforce, and will continue efforts to provide a path for predominantly African-American students to continue to graduate school in physics and astronomy. SWGO will be built in a Spanish speaking country, which will enhance outreach to Hispanic communities.A survey instrument provides daily unbiased monitoring for variable sources, as well as near-real-time alerts to other instruments, and the wide field makes it sensitive to particle accelerators in the local Galactic neighborhood. The detection of very extended TeV gamma-ray emission around nearby pulsars is interpreted as halos of gamma rays that are produced by electrons and positrons interacting with the ambient interstellar radiation field outside the classical pulsar wind nebulae. SWGO will be ideally suited to study the acceleration and propagation of particles within them in unprecedented detail. It will also enable studies of the galactic center region and uniquely contribute to the search for and study of sources of cosmic rays with energies in excess of 1 PeV. All gamma-ray data will be made publicly available. Supported by this initial SWGO award the team will focus on detector simulation, air shower data reconstruction algorithm development, and electronics design.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

随着中微子和引力波探测设施的成功开发，以及下一代伽马射线探测器的部署，未来十年将为多信使天文学提供大量机会。高海拔水切伦科夫（HAWC）伽马射线天文台是一个非常成功的调查仪器，并激发了中国雄心勃勃的努力，但也将设在北方。该项目将进行南半球下一代地面测量仪器所需的基本研究和开发：南半球宽视场伽马射线观测台。这项工作还有助于保持美国在地基伽马射线仪器方面的领导地位。该团队致力于提高STEM劳动力的多样性和卓越性，并将继续努力为主要是非洲裔美国学生继续攻读物理学和天文学研究生院提供一条道路。 SWGO将建在一个讲西班牙语的国家，这将加强对西班牙裔社区的宣传。一个调查仪器每天提供对可变来源的无偏见监测，以及对其他仪器的近实时警报，宽场使其对当地银河系附近的粒子加速器敏感。在附近的脉冲星周围探测到非常广泛的TeV伽马射线发射，被解释为伽马射线晕，是由电子和正电子与经典脉冲星风星云外的环境星际辐射场相互作用产生的。 SWGO将非常适合以前所未有的细节研究粒子在其中的加速和传播。它还将使银河系中心区域的研究，并独特地有助于搜索和研究能量超过1 PeV的宇宙射线源。所有伽马射线数据都将公开。在最初的SWGO奖的支持下，该团队将专注于探测器模拟、空气簇射数据重建算法开发和电子设计。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
