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