个人简介
Dr. Wang’s research areas include classical and quantum theories of gravity, and their applications to astrophysics and cosmology. Currently research topics include gravitational wave physics and cosmology, black hole physics, quantum cosmology and the very early universe, and the nature and origins of dark matter and dark energy.
One of the remarkable discoveries in the history of physics is the gravitational waves by The Laser Interferometer Gravitational-Wave Observatory (LIGO), emitted during the coalescences of two compact astrophysical objects, such as black holes and neutron stars, which marks the beginning of a new era – the GW astronomy, and opens an unprecedented new window onto the cosmos. ``The possibilities for discovery are as rich and boundless as they have been with light-based astronomy.” Such studies have gained further momenta from the recently direct observations of the supermassive black hole at the center of Messier 87 by Event Horizon Telescope (EHT).
Another landmark in the development of modern cosmology is the discovery that currently our universe is in an accelerating expansion phase. In Einstein's theory of general relativity, to account for such an expansion, a new component to the matter fields of the universe with a large negative pressure is needed, the so-called dark energy. Recent astronomical observations indicate that our universe is flat and currently consists of approximately 68% dark energy, 27% dark matter, and 5% baryon matter and radiation.
