Yunnan Provincial Key Laboratory for Survey Science aims to address fundamental astronomical questions by leveraging the Multi-channel Photometric Survey Telescope (Mephisto) at Yunnan University and the China Space Station Telescope. The laboratory assembles an internationally influential research team active in frontier fields like multi-messenger, full-band time-domain astronomy, the Milky Way and nearby galaxies, and cosmological studies.
I Research Areas
1.Platform Development and Big Astronomical Data Processing
1) Complete the construction of Mephisto and conduct multi-channel photometric surveys.
2) Analyze survey data using deep learning for real-time identification/classification of variable/transient sources, advancing big data, AI, and data mining.
3) Participate in the development of China Space Station Telescope and data pipeline research.
2. Cosmic Variable and Transients
1) Conduct high-frequency true-color time-domain surveys of nearby galaxies to study statistical properties of variable/transient sources and their correlations with host galaxies.
2) Identify and monitor cosmic variables/transients to uncover new phenomena and physics.
3) Reveal physical laws in extreme environments.
3. Structure and Assembly History of the Milky Way and Nearby Galaxies
1) Perform high-precision photometric surveys of stars in the Milky Way and Local Group.
2) Discover thousands of extremely metal-poor stars and measure physical parameters of hundreds of millions of stars.
3) Unveil the structure, stellar populations, and assembly history of the Milky Way and nearby galaxies.
4. Fundamental Problems in Cosmology
1) Investigate cosmic origins, evolution, matter composition, and the Hubble tension using multi-messenger observations.
2) Conduct pre-research on data analysis and error control for cosmology with the China Space Station Telescope.
II Operations and Management
The laboratory adheres to the Yunnan Provincial Key Laboratory Management Measures (Yunke Regulation [2023] No. 3), adopting a management model of “merit-based support, open sharing, periodic evaluation, and multi-source funding” and an operational mechanism of “openness, mobility, collaboration, and competition.”
An academic committee composed of leading global experts oversees scientific guidance. Daily operations are managed by the laboratory director, with decision-making guided by the academic committee.
Established regulations include: Interim Operational Management Rules, Equipment Management and Usage Guidelines, Safety Management Protocols
III Strategic Plans
Integrate resources, attract globally competitive talent, tackle astronomical challenges, cultivate optical observation experts, and build a world-class astronomical research center and optical observation base.
IV Expected Outcomes
Build an internationally influential team in cutting-edge survey science. Establish a first-class observational platform for pioneering research, positioning the laboratory as a global “peer-runner” in survey astronomy.
1. Complete a 10-year multi-channel photometric time-domain survey, discover new celestial phenomena, and publish high-precision catalogs and legacy datasets.
2. Train experts in astronomical observation and big data analysis.
3. Foster innovation through international collaborations, open research projects, and conferences to enhance global visibility.
