Intensity mapping cosmology with radio telescopes

点击翻译按钮获取中文摘要

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.
