Cosmology is the study of the large-scale properties of the universe as a whole. Our goal in cosmological studies is to understand the nature, origin, and evolution of the whole universe. The universe is the sum of all matter and energies, space and time, and the laws of nature. Cosmology involves the formation of theoretical models to describe our universe, which then provide us with specific predictions for physical phenomena that can be tested with astronomical experiments.
The research of the cosmology group at IAA has been focusing on the measurement analysis of the cosmic microwave background (CMB) and using multiwavelength observation and analysis on galaxy formation at high redshift and galaxy clusters in order to understand their properties and place constraints on the properties of dark energy (DE) and dark matter (DM).
