Description
Future observation with next-generation large-area radio telescopes are expected to discover radio pulsars closely orbiting around Sagittarius A (Sgr A), the supermassive black hole (SMBH) in our Galactic Center (GC). Such a system can provide a unique laboratory for testing gravity theories , as well as the astrophysics around the GC. We will introduce our recent studies about prospects for using the SMBH-pulsar system to test gravity. Including testing the no-hair theorem in General Relativity, constraining the vector charge of Sgr A, probing the small-scale dark matter distribution around Sgr A and so on.
