We study galaxy formation and evolution in a broad term. Using multi-wavelength data, we investigate the related subjects, including ultra-luminous infrared galaxies, star-forming galaxies, galaxy interacting and merging, starburst on the galaxy scale, and co-evolution between galaxies and their central black holes. We also use numerical tools to study the evolution of galaxies, e.g. the semi...

Our current research focuses on data analysis in cosmic microwave background, especially those related with the non-Gaussianity (both primordial and secondary). The primary goal is to constrain physical models, such as inflation, on the very early universe. We are extending our work to related studies on large scale structure galaxy survey, and redshifted 21cm background. we are also interested...

The research on AGN and quasars at TAC involves multi-wavelength observational studies to characterize the spectral properties of AGNs and investigate energy mechanism and structures of these objects. Other projects include studies of post-starburst quasars to investigate the connections between AGN activities, black hole growth and host galaxy evolution. The multi-wavelength data obtained fr...
