Tianlai Project

The Tianlai Project is an survey (with associated radio telescopes) for intensity mapping the 21-cm line, with the goal of detecting baryon acoustic oscillations (BAOs). One telescope, the Tianlai Cylinder Array is similar in concept to Canadian Hydrogen Intensity Mapping Experiment (CHIME), 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. The project also has an array of sixteen dishes, the Tianlai Dish Array. A back end instrument for the dishes to detect fast radio bursts (FRBs) has been added.
