平方公里阵列

The Square Kilometre Array

Joseph Lazio

摘要:

平方公里阵列(SKA)是下一代射电望远镜,将解决天体物理学,物理学和天体生物学中的基本问题。国际科学界已经制定了一系列关键科学计划:(1)走出黑暗时代和再电离时代,(2)星系演化,宇宙学和暗能量,(3)宇宙磁场的起源和演化,(4)使用脉冲星和黑洞的强场引力测试,以及(5)生命/天体生物学的摇篮。此外,还有一种“探索未知”的设计理念,其目标是保持设计尽可能灵活,以允许未来的发现。SKA的一个重大挑战和机遇是获得比传统射电望远镜更宽的视场。鉴于本次会议对宇宙磁学和星系演化的广泛覆盖,我强调了一些扩大视野将为其他关键科学计划带来的机会。

英文摘要:

The Square Kilometre Array (SKA) is intended as the next-generation radio telescope and will address fundamental questions in astrophysics, physics, and astrobiology. The international science community has developed a set of Key Science Programs: (1) Emerging from the Dark Ages and the Epoch of Reionization, (2) Galaxy Evolution, Cosmology, and Dark Energy, (3) The Origin and Evolution of Cosmic Magnetism, (4) Strong Field Tests of Gravity Using Pulsars and Black Holes, and (5) The Cradle of Life/Astrobiology. In addition, there is a design philosophy of "exploration of the unknown," in which the objective is to keep the design as flexible as possible to allow for future discoveries. Both a significant challenge and opportunity for the SKA is to obtain a significantly wider field of view than has been obtained with radio telescopes traditionally. Given the breadth of coverage of cosmic magnetism and galaxy evolution in this conference, I highlight some of the opportunities that an expanded field of view will present for other Key Science Programs.
