Abstract
Since the detection of gravitational waves emitted by binary black hole mergers made by the LIGO-Virgo Collaboration, the search for the stochastic gravitational wave background (SGWB) has become the next milestone in a new era of gravity-wave astronomy and cosmology. Recently, the pulsar timing arrays have detected for the first time a nanohertz SGWB. We aim to understand the origin and property of the SGWB, and go beyond classical and Einstein's gravity, using the SGWB to test general relativity and probe the quantum nature of GWs.
Biography
Kin-Wang Ng obtained his Ph.D. in Physics from University of Minnesota, Minneapolis in 1989. He was recruited as a postdoctoral fellow in Institute of Physics, Academia Sinica and has become a faculty member since then. He is also a joint research fellow of Institute of Physics and Institute of Astronomy and Astrophysics, Academia Sinica. His major research interests are astroparticle physics and cosmology. He has made prominent contributions to indirect detection of dark matter, cosmic microwave background polarization, inflationary black holes and gravitational waves. He was the recipient of the Young Research Award of Academia Sinica, 1998. He served the Executive Committee member of National Center for Theoretical Sciences and currently being a General Council member of Asian Pacific Center for Theoretical Physics.
