Dear Colleagues,

To promote scientific discussions during this pandemic, we are organizing an online seminar series, i.e. Copernicus Webinar Series, seeking the most outstanding speakers to introduce innovative ideas and important progress in the field of gravity and cosmology. This series is named after the famous Polish Astronomer, Nicolaus Copernicus, whose discovery eventually marked the dawn of modern science.

We would like to invite you to take part in the upcoming 103rd Copernicus Webinars.

Time:                 26th July, Tuesday, 3pm CEST (9 pm Beijing, 10 pm JST, 9am EDT)

Speaker:            Jianwei Mei (Sun Yat-sen University)


An introduction to the TianQin Project


The TianQin Project plans to deploy around 2035 three satellites to form an equilateral triangle constellation, TianQin, in an orbit centered on the Earth with an altitude of about 105 kilometers, to detect gravitational waves in space. TianQin is expected to open the gravitational wave detection window in the frequency band of 10-4 Hz ~ 1 Hz, opening our eyes towards the nature of gravity, the origin of black holes and the history of the universe. The ultimate scientific detection capability of TianQin depends on the level of breakthroughs that can be achieved with various key technologies, such as high-precision space inertial refence and long baseline laser interferometry, etc., which are all being researched. In this talk, I will make a brief introduction to the TianQin project.
