School of Astronomy and Space Science 




The School of Astronomy and Space Science of Nanjing University was established in March 2011, and its predecessor, the Department of Astronomy, was founded in 1952. It earns the longest history and a high reputation of all the astronomy departments in China. The school has cultivated many astronomers who are currently active in academic circles.

  

Today the school has 2 undergraduate programs, respectively under 2 departments, the Department of Astronomy and the Department of Space Science & Technology. It also consists of several laboratories, such as Key Laboratory of Modern Astronomy and Astrophysics, named by the Ministry of Education, Central Laboratory for Teaching, Solar Tower Laboratory, Center for Nonlinear Sciences, and Planetary Science and Deep Space Exploration Laboratory. Furthermore, the school owns the national first-level key discipline of astronomy, including two national second-level key disciplines: Astrophysics and Astrometry & Celestial Mechanics. 





The school’s current research activities cover high-energy astrophysics, solar physics, galaxies and cosmology, extra-solar planets, aerospace dynamics, astrometry and space science.

  

The School has a strong faculty consisting of both distinguished senior scholars and a large number of young academic leaders. There are 44 faculty members in total, including 20 professors, with 4 academicians of the Chinese Academy of Science, 4 Cheung Kong Scholars, 1 Chief Scientist for the National 973 Basic Research Program, 7 National Science Fund for Distinguished Young Scholars Winners, 7 China Cross-Century Talent Raising Program Winners, and 4 Youth Qianren Professors. Sponsored by the National Science Foundation of China and National Key Fundamental Research Programs, the school has obtained fruitful academic achievements and won many national/provincial awards.

  

In order to foster a new collaborative mode between universities and observatories, in 2010, Nanjing University, Purple Mountain Observatory and Nanjing Institute of Astronomical Optics & Technology signed an agreement aimed at jointly establishing the Center for Astronomy and Space Science on the Xianlin Campus of Nanjing University.

  

Moreover, after a series of discussions and consultations, Nanjing University, Peking University, National Astronomical Observatories, Purple Mountain Observatory and University of Science & Technology of China co-founded the Collaborative Innovation Center of Modern Astronomy and Space Exploration in December 2012.

  

The school also explores the channels of cooperation with overseas partners to push forward the process of internationalization and has established friendly and cooperative relationship with over 20 institutes of higher education in the USA, UK, Australia, Japan and so on. Its partners include Harvard University, California Institute of Technology, Massachusetts Institute of Technology, Kyoto University, University of California Santa Cruz, University of California Los Angeles, University of Tokyo, University of Sydney, and Paris Observatory.

  

In August 2014, the school moved into a new building which covers 12,000 square meters. The new building well meets the needs of research, experiments, teaching and academic activities, and will play a significant role in the school’s development in the decades to come.



History


In 1952, the Department of Astronomy, Nanjing University, was established, integrating the Department of Astronomy of Sun Yat-sen University and the Astronomy & Arithmetic Department of Qilu University. The director was Professor Zhao Que-min.


In 1955, the Department of Astronomy and the Department of Mathematics, Nanjing University, merged into the new Department of Mathematics & Astronomy.


In 1962, the Department of Astronomy was re-established and was headed by professor Dai Wen-sai.


From 1972 to 1976, the department enrolled 183 students. In 1977, the National College Entrance Examination was resumed, and the department began to recruit graduate students since 1978 and doctoral students since 1987.


In 1993, the Department of Astronomy was granted the title “National Training Bases of Astronomy Talents” and began to be funded by the National Natural Science Foundation of China.


In March 2011, the School of Astronomy and Space Science was established. 



Discipline Construction


High Energy Astrophysics Group

Focus on supernovae and supernova remnants, Gamma-ray bursts and GRB cosmology, compact stars, high-energy cosmic rays and other relevant astronomical phenomena. The faculty plans to involve the most violent outbreaks in outer space, which will be quite significant for the study of evolution of stars, galaxies and the universe.

Solar Physics Group


The research addresses the origin, structure and evolution of solar activities, especially the physical mechanisms of the most energetic solar eruptions such as solar flares and coronal mass ejections. The theoretical part includes MHD and radiative hydrodynamic simulations, and the observational part covers a wide range from radio to hard X-ray.

Galaxies and Cosmology Group


The research focuses on the galaxy-center black hole activities, starburst galaxies and active galactic nucleus, chaos in the galaxy and cluster dynamics, stellar structure and galactic-disk thickness of neighbor galaxies. The research uses observational data from large ground and space telescopes and theoretical models to establish the physical processes that is, triggering, evolution and inter-relation of neighbor galaxies stellar activities and nuclear activities.

Space Science Laboratories


Facility


The Optical & Near-Infrared Solar Eruption Tracer (ONSET), located at Fuxian Lake, Yunnan Province.


Construction of the Time Domain Survey Telescope (TDST)

  • TDST focuses on searching of planets around bright star (Vmag<12) near North ecliptic Pole. It will provide the light curves of these bright stars with a high precision. Utilizing the light curves of G, K, F stars, planet candidates with period 1-5 year can be detected.

  • TDST will give star catalogues around North Ecliptic Pole before TESS, and is helpful to TESS mission. Additionally, the long period planets detected by TDST will be an important complementary for TESS and Plato. Planets around dwarfs are also expected. All these planets are suitable to be followed up by worldwide telescopes.
