    Collaboration Home

    I am involved in several large projects, including Dark Energy Spectroscopic Instrument (DESI), Subaru Prime Focus Spectrograph (PFS), the Black hole-Host Lifecycle Evolution, the PKU-KIAA Innovation NSFC Group, and so on. I am also involved in other projects.


    I am a member of the DESI (Dark Energy Spectroscopic Instrument) collaboration. DESI is a multi-fiber optical spectrograph funded by the U.S. Department of Energy Office of Science. It will be conducted on the Mayall 4-meter telescope at Kitt Peak National Observatory. DESI will obtain optical spectra for tens of millions of galaxies and quasars, constructing a 3-dimensional map spanning the nearby universe to 10 billion light years. It will measure the effect of dark energy on the expansion of the universe, via various techniques such as the measurement of baryon acoustic oscillations. For more details, see: http://desi.lbl.gov.


    I am a member of the Subaru PFS (Prime Focus Spectrograph) collaboration. PFS is a spectrograph system with a fiber positioner system to be mounted at the prime focus of the Subaru telescope. The instrument allows simultaneous spectral observation of up to 2400 astronomical targets in a wide field of view of 1.3 degree diameter at a time. It will be the most powerful optical spectrograph in the near future. It will find clues to help us answer questions such as, how did the Universe begin, does it have an end, why do we exsit.

    Black hole-Host Lifecycle Evolution

    I am one of the four group leaders of the Black hole-Host Lifecycle Evolution project. This project is a large, long-term program funded by the Ministry of Science and Technology of China, devoted to four areas related to the general theme of the coevolution of supermassive black holes and galaxies: (1) measurement of black hole masses in active galaxies, (2) study of physical properties (stars, gas, dust, star formation rate) of host galaxies, (3) search for and systematic characterization of high-redshift quasars, and (4) theoretical investigation of the physics of the central engine (accretion disk, outflows, feedback) of active galaxies. The project, led by Luis C. Ho, is a collaboration of 17 core investigators from six institutions in China (KIAA, Institute of High-energy Physics, National Astronomical Observatory of China, Shanghai Astronomical Observatory, Nanjing University, and University of Science and Technology of China). For more details, see here.

    PKU-KIAA Innovation NSFC Group

    I am one of the core members of the PKU-KIAA Innovation NSFC Group (PKING). PKING is supported by the prestigious National Science Foundation of China Innovation Group program. I am one of the six original members of the innovation group. PKING consists of three subgroups that cover three broad research fields: gravitational astrophysics, interstellar medium, and sky-survey science. I am the coordinator of the sky-survey science group. Our group members are actively involved in many ongoing and future leading survey projects, such as SDSS, DESI, PFS, CSST, LSST, LAMOST, NGVS, ASAS-SN, etc. These surveys cover a wide range of astrophysical topics, including nearby galaxies, distant universe, transient sky, etc. For more details, see: http://kavli.pku.edu.cn/pking/ and http://kavli.pku.edu.cn/SSSgroup/.
