Associate Professor in Gravitational Physics

Sun Yat-sen University - The TianQin Research Center for Gravitational Physics

1. About Us

The TianQin Research Center for Gravitational Physics, Sun Yat-sen University, is dedicated to accomplishing the TianQin Project.

The TianQin Project was proposed by Jun Luo in 2014 and the goal is launch and operate the space-based gravitational wave (GW) observatory, TianQin, around 2035. The mission concept of TianQin envisions a constellation of three satellites on a geocentric orbit with radius of about 105 km. The satellites are carefully controlled to provide ultra clean and stable environment for the scientific payloads, allowing gravity to take full governance of the motion of a set of test masses and allowing laser interferometry to reach extremely high precision. In this way, the minute variation in the distance between the test masses (partially caused by gravitational waves) can be measured with inter-satellite laser interferometry.

The major sources of TianQin include the inspiral of ultra-compact Galactic binaries, the inspiral of stellar mass black holes, the extreme mass ratio inspirals, the merger of massive black holes, and possibly also GWs from the very early universe or from exotic sources such as cosmic strings. TianQin is expected to provide key information on the astrophysical history of galaxies and black holes, the dynamics of dense star clusters and galactic centers, the nature of gravity and black holes, the expansion of the universe, and possibly also the fundamental physics related to the phase transition of the universe. To achieve the scientific goals, two core technology requirements have to be met: The residual acceleration on the test masses must reach the order 1*10-15 m s-2/Hz1/2 and the noise of displacement measurement with inter-satellite laser interferometry must reach the order 1*10-12m/Hz1/2, both in the millihertz frequency range.

The TianQin Project has received significant support from both the central and the local governments. The TianQin Research Center for Gravitational Physics was established in April 2016. As of November 2019, the center has grown to have about 40 research staff (including 2 academicians), the new TianQin center building (with an area of about 38000 square meters) is scheduled to open in the middle of 2020. A new laser ranging station (equipped with a 1.2-meter telescope) for the TianQin Project has been built and has successfully ranged to all the five retro-reflectors on the Moon. The construction of a new cave lab and a ground simulation facility is currently underway. Major projects, such as the Lunar Relay Satellite Laser Ranging Experiment and the TianQin-1 experimental satellite, are also being carried out. The TianQin-1 experimental satellite has been launched on 20 December 2019, and the performance of all payloads has met (and some has exceeded) the design specifications.
