Black hole physics and its properties (mass and spine), gamma-ray burst including its explosion mechanisms and afterglow evolution, high-energy astrophysics

We made a first-ever precise measurement to the distance, mass, and spin for the black hole in Cyg X-1 system which is the first black hole prototype.
Using MCMC method, we did a multi-band and careful analysis to the afterglow of the first high-redshift Gamma-Ray Burst (GRB), GRB 050904, which is located at z=6.295, and compared its properties with the ones at low redshift.
