About Us

The Center for Gravitation and Cosmology (CGC) is a research center founded in 2017 at Yangzhou University, in the Jiangsu Province of China. It is an initiative of the BRICS-Association of Gravity and Cosmology, with support from the BRICS countries (Brazil, Russia, India, China and South Africa). The center is currently hosted on the 3rd floor of the College of Physical Sciences and Technology building, on the scenic Slender West Lake campus.
