The main goal of our group is to study the cosmic gamma-ray bursts, X-ray binaries, soft gamma-ray repeaters, etc.. Gamma-Ray Bursts (GRBs) is one of the most active areas in modern astrophysics. GRBs are short and intense gamma-ray emission lasting about tens seconds, they come from the cosmological distances and from random directions in the sky.

  The isotropic energy can reach 10⁵⁴ergs, making them the most luminous objects in the sky. The most distant GRB has been detected recently with redshift z=8.3, which indicates that GRBs can be used to probe the early universe. X-ray binaries is one of the important aspects of X-ray astronomy, which includes high mass X-ray binaries and low mass X-ray binaries. Our works are mainly focusing on the radiation process of GRBs, especially in the afterglow phase, and investigate the X-ray binaries through multi-wavelength observations.
