科学与ASKAP -澳大利亚平方公里阵列探路者
Science with ASKAP - the Australian Square Kilometre Array Pathfinder
摘要：
厘米和米波天文学的未来在于平方公里阵列（SKA），这是一个由17个国家组成的联盟正在开发的望远镜。SKA的灵敏度将是现有无线电设备的50倍。SKA的大部分关键科学将通过在300 MHz到几GHz的频率下对宇宙进行大面积成像来解决。澳大利亚的SKA探路者（ASKAP）在这个频率范围内瞄准，并通过在抛物面反射器上开发和部署相控阵馈电系统实现瞬时广域成像。这种大视场使ASKAP成为一种前所未有的天气望远镜，有望在SKA关键科学领域取得实质性进展。ASKAP的中心核心将位于西澳大利亚内陆的Murchison射电天文台，这是地球上无线电最安静的地点之一，也是国际社会选定的SKA潜在地点之一。在介绍ASKAP之后，本文件共分七章，介绍ASKAP的具体科学方案。地理位置、技术创新和科学计划的结合将确保ASKAP成为世界领先的射电天文学设施，与SKA的科学和技术方向保持密切一致。一个简短的总结章节强调了这一点，并考虑了发现空间。
英文摘要：
[ABRIDGED VERSION] The future of cm and m-wave astronomy lies with the Square Kilometre Array (SKA), a telescope under development by a consortium of 17 countries. The SKA will be 50 times more sensitive than any existing radio facility. A majority of the key science for the SKA will be addressed through large-area imaging of the Universe at frequencies from 300 MHz to a few GHz. The Australian SKA Pathfinder (ASKAP) is aimed squarely in this frequency range, and achieves instantaneous wide-area imaging through the development and deployment of phase-array feed systems on parabolic reflectors. This large field-of-view makes ASKAP an unprecedented synoptic telescope poised to achieve substantial advances in SKA key science. The central core of ASKAP will be located at the Murchison Radio Observatory in inland Western Australia, one of the most radio-quiet locations on the Earth and one of the sites selected by the international community as a potential location for the SKA. Following an introductory description of ASKAP, this document contains 7 chapters describing specific science programmes for ASKAP. The combination of location, technological innovation and scientific program will ensure that ASKAP will be a world-leading radio astronomy facility, closely aligned with the scientific and technical direction of the SKA. A brief summary chapter emphasizes the point, and considers discovery space.
