cosmology and particle astrophysics, including dark matter detection, dark energy model and detection, cosmic microwave background, large scale structure, formation of first generation of luminous objects and reionization
My major research areas are the physics of compact stellar objects, e.g. structure, cooling, glitches and other internal activities of neutron stars, and high energy astronomy, e.g. X-ray and gamma-ray emission mechanisms of pulsars. I am interested in the possible central engines of gamma-ray bursts and in using the gamma-ray bursts to probe the properties of the early Universe. I also work on high energy phenomena related to stellar capture

Professor Liu's main research interest is spectroscopic study of emission line nebulae, with an emphasis on the physical processes and radiative mechanisms governing photoionized gaseous nebulae. Studies of emission line nebulae yield information of stellar nucleosynthesis and the enrichment of the interstellar medium, and of the chemical evolution of galaxies. Currently, Prof. Liu is leading a large spectroscopic survey towards the Galactic anticenter with the newly built Chinese Large
