The neutral hydrogen atoms in the Universe radiates with a wavelength of 21 cm, on large scales the intensity of this radiation is proportional to the matter density. By radio observation, one can probe the cosmic large scale structure distribution. Using the baryon acoustic oscillation signatures in the matter power spectrum as standard rulers, high precision cosmological measurements can be obtained, and the dark energy equation of state parameter w measured. This provides an important tool for dark energy observation.

The TianLai Project -- A Radio Observation Experiment for Dark Energy


The Tianlai project is an experiment aimed at detecting dark energy by measuring the baryon acoustic oscillation (BAO) features in the large scale structure power spectrum, which can be used as a standard ruler. The basic plan is to build a radio telescope array, and use it to make 21cm intensity mapping observations of the neutral hydrogen which traces out the large scale structure of matter distribution.

Currently, the Tianlai collaboration includes scientists and engineers from China, Canada, France, and USA.

The word “Tianlai” literally means “heavenly sound”, it was coined by the ancient philosopher Zhuangzi (or Chuang Tzu, 369BCE-286BCE) .
