在过去的几十年里，标准宇宙学模型已经建立，其参数也得到了高精度的测量，但宇宙学中仍有许多基本问题有待解决，如早期宇宙的物理、宇宙加速的起源、暗物质的性质等。即将到来的射电望远镜，平方公里阵列（SKA），这将是世界上最大的，将能够开辟宇宙学的新前沿，并将成为未来十年宇宙学最强大的工具之一。SKA进行的宇宙学调查不仅有可能回答这些基本问题，而且还可以提供精确的宇宙学。在这篇文章中，我们简要回顾了SKA的作用，从现代宇宙学的观点。讨论了SKA-JP宇宙学科学工作组领导的宇宙学科学。
In the past several decades, the standard cosmological model has been established and its parameters have been measured to a high precision, while there are still many fundamental questions in cosmology; such as the physics in the very early universe, the origin of the cosmic acceleration, and the nature of dark matter. The forthcoming radio telescope, the Square Kilometre Array (SKA), which will be the world's largest, will be able to open a new frontier in cosmology and will be one of the most powerful tools for cosmology in the coming decade. The cosmological surveys conducted by the SKA would have the potential not only to answer these fundamental questions but also deliver precision cosmology. In this article we briefly review the role of the SKA from the viewpoint of modern cosmology. The cosmological science led by the SKA-Japan Consortium (SKA-JP) Cosmology Science Working Group is also discussed.
