Keynote Speaker
Di Li , Tsinghua University, China
Dr. Li is a radio astronomer. He is a Chair Professor of Tsinghua University and the former Chief Scientist of FAST. He pioneered several observing and data analysis techniques, including HI Narrow Self-Absorption(HINSA) and a new inversion algorithm for solving the dust temperature distribution.These techniques facilitated important measurements of star forming regions , such as their formation time scale and interstellar magnetic field (as a Nature cover article). Dr. Li has led and/or made multiple significant discoveries,including the first detection of interstellar molecular oxygen and the first persistently active fast radio bursts(FRB), the largest FRB bursts set, etc. He is leading the Commensal Radio Astronomy FasT Survey(CRAFTS), which is the world's first commensal survey of HI, pulsars, and FRBs. CRAFTS has discovered more than 200 pulsars, more than 8 FRBs, released 5000 deg2 HI sky maps. He has published more than 350 peer-reviewed journal articles with more than 10000 citations. He won the 2024 Marcel Grossmann Award for “For his groundbreaking contributions to the scientific definition of the most sensitive radio telescope and his numerous innovations in characterizing the dynamic universe”. His numerous other awards and leadership roles include the 2005 National Research Council (US)Resident Research Fellowship based on “his outstanding research capabilities ... as a result of national competition”; the 2022 Distinguished Achievement Award of the Chinese Academy of Sciences(CAS); the 3rd National Innovation Award; the Steering Committee of Australia Telescope National Facility (ATNF); the Square Kilometer Array Science and Engineering Advisory Committee(SEAC); the advisory panel of the Breakthrough Listen initiative, etc.
Title: The Commensal Radio Astronomy FAST Survey (CRAFTS) and high-throughput data analysis
Abstract: The Five-hundred-meter Aperture Spherical radio Telescope (FAST) is currently the largest single-dish radio telescope in the world with unprecedent high sensitivity and survey speed. The Commensal Radio Astronomy FAST Survey (CRAFTS) is one of the FAST key science projects. Utilizing the world’s-first high cadence noise injection technology, CRAFTS aims to carry out the Galactic neutral hydrogen imaging, neutral hydrogen galaxy search, pulsar search, and fast radio burst (FRB) search simultaneously, doubling the survey efficiency of FAST. The CRAFTS survey faces big challenge from the data transportation, storage, and analysis for huge amount of data collected every day. We have built a high-throughput data real-time processing technology platform, and developed intelligent computational techniques to meet these new requests from FAST surveys.
