Tianlai Project

(21cm line intensity mapping project)

The Tianlai Project is an survey (with associated radio telescope) for intensity mapping the 21-cm line, with the goal of detecting baryon acoustic oscillations (BAOs). The telescope, which is similar in concept to Canadian Hydrogen Intensity Mapping Experiment (CHIME), is an array of adjacent stationary cylindrical telescopes each with many receivers. A pilot array is in operation that has three such telescopes covering 700-800 MHz to detect the 21-cm line within 1.03 > z > 0.78.
