The Kavli Institute for Astronomy and Astrophysics (KIAA) is jointly supported by Peking University and an endowment made possible by a generous gift from the Kavli Foundation, USA. KIAA was established in June, 2006 and started operation in 2007. KIAA's mission is to establish an international center of excellence in astronomy and astrophysics that promotes the development of basic astrophysical research. Its primary goal is to foster frontier research in a vibrant intellectual environment. With English as its working language, KIAA is engaged in theoretical and observational initiatives, development and utilization of astronomical facilities, and training of undergraduate and graduate students and postdoctoral fellows. KIAA regularly sponsors thematic workshops, conferences, and a range of other academic activities to facilitate scientific exchange with the domestic and international astronomy community. It is establishing exchange and visiting programs with other Kavli institutes and a network of universities and astronomy centers worldwide.
The program of KIAA focuses on four major areas of astrophysics: 1) observational cosmology, galaxy formation and evolution; 2) star formation, stellar and planetary systems; 3) gravitational physics and high-energy phenomena; and 4) computational astrophysics.
The Institute is under the leadership of its Director Luis C. Ho, Associate Director X.-B. Wu, Gregory J. Herczeg, and coordinator J. S. Chen. An international Science Advisory Committee provides guidance concerning proposed academic activities, assistance on major projects to set research directions, and review of new faculty appointments. A Governing Board, which reports to the President of Peking University, has been established to oversee the management and operations of the Institute. KIAA works closely with the Department of Astronomy, via coordination of research activities, sharing of research facilities and resources, training and supervising of students, and joint participation in the routine operations of the Institute. Together with several joint appointments with the Department of Astronomy and other institutions, KIAA currently has 25 professors, approximately 30 postdoctoral fellows, a number of visiting scholars, and five administrative staff members. The following is a chart showing the overall organizational structure of KIAA.
研究所的主要研究领域包括：1) 观测宇宙学，星系的形成与演化；2) 恒星形成，恒星与行星系统; 3) 引力物理和高能现象；4) 计算天体物理。
