Prospects of testing dark matter model with pulsar around Sgr A* Hu, Zexin In the future, with the next generation telescopes like SKA, we may detect pulsars orbiting closely to the supermassive black hole in our galaxy center. In this talk, I will introduce the prospects of constraining dark matter distribution near the galactic center with timing a pulsar around Sgr A*. (The work is summarizing to a paper)
