Description
摘要：The 21cm line of neutral hydrogen is a promising tool for cosmology. I will first briefly review the present status of 21cm cosmology, then I will describe two projects: the Tianlai 21cm intensity mapping experiment in Xinjiang, and the Discovering Sky at the Longest wavelength (DSL, also known by the Chinese name Hongmeng) project, which is a proposed lunar orbit array to map the sky at ultralong wavelength and measure the 21cm global spectrum from cosmic down.
