报告摘要

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Pulsars are powerful tools for studying fundamental physics and gravitational physics, such as testing general relativity and alternative theories, studying the properties of neutron star matter, and searching for gravitational waves from supermassive black hole binaries. In this talk, I will highlight the recent results on strong-field gravity tests with the Double Pulsar system PSR J0737-3039A/B using MeerKAT data, in particular on higher-order gravitational signal propagation effects and the prospects of constraining the equation of state. Then I will demonstrate the prospects of testing scalar-tensor gravity using PSR 2222-0137 and pulsar-black hole systems with the sensitivity of FAST. Finally, I will discuss the recent advances in nanohertz gravitational wave detection with pulsar timing arrays.
