Gravitational Wave and testing of gravity Other events...
Gravitational waves (GWs) provide the excellent opportunity to test General Relativity in strong fields. In this talk, by comparing General Relativity and its alternative, the general screened modified gravity, we introduce the testing of gravity in solar system with PPN framework, in binary pulsars with PPK framework, and in GW bursts. In the last case, we introduce the model-dependent (waveforms of GWs in various alternative theories of gravity) and model-independent comparisons (by PPE framework, GW polarization, GW speed, time-dependence of G, parity symmetry etc.).
Speaker(s) Wen Zhao received his PhD degree from University of Science and Technology of China (USTC). He then worked as a postdoc in Cardiff University, Korea Astronomy & Space Science Institute, and Niels Bohr Institute. In 2012, he returned to USTC as a professor in Department of Astronomy. Prof. Zhao’s research interest includes: Cosmology, Inflationary physics, Cosmic Microwave Background radiation, primordial GW, dark energy, GW astronomy and GW cosmology.
