Intensity mapping cosmology with radio telescopes

该项目旨在为现有观测和未来数据的数据分析开发一个多功能基础设施。利用射电望远镜绘制氢强度图的宇宙学是预期的平方公里阵列的关键科学领域。现有数据集的结果将限制宇宙的膨胀率和70亿年前的引力定律，这是其他观测无法获得的。新技术将通过测量光学星系的气体含量来改善光学和无线电数据之间的协同作用。预计这将促进对银河系如何演化的了解。

This project aims to develop a versatile infra-structure for the data analysis of existing observations and future data. Cosmology using intensity mapping of hydrogen with radio telescopes is a key science area for the anticipated Square Kilometre Array. The results of available datasets will constrain the expansion rate of the Universe and the laws of gravity about 7 billion years ago, inaccessible by other observations. New techniques will improve the synergies between optical and radio data by measuring the gas content of optical galaxies. This is expected to advance knowledge of how the galaxy evolves.
