Abstract：To statistically investigate the star formation process in the Galaxy, we initiated the ALMA-ATOMS/QUARKS survey programme at ALMA, which observed about 140 high-mass proto-clusters at band 3 and band 6 under an angular resolution of ~0.3-2 arcsec. The main science goals of the ALMA-ATOMS/QUARKS survey project are: (i) to deepen the understandings of the dense gas star formation law by studying the spatial distributions of various dense gas tracers in a large sample of Galactic clumps and evaluating how much of molecular gas is participating in star formation; (ii) to investigate how stellar feedback from formed OB (proto)stars influences the surrounding gas distributions and the next generation of star formation in their natal clumps; (iii) to resolve filaments and to study their roles in protocluster formation. I will talk about the current status of this survey and future plans.
Bio：Prof. Tie Liu is an observational radio astronomer at Shanghai Astronomical Observatory with expertise on (sub)millimeter observations with both single dishes (e.g., JCMT) and interferometers (e.g. ALMA). His primary research interests include star formation and astrochemistry. He obtained his PhD from Peking University in 2013. And then he continued his research in Chile (University of Chile), Korea (KASI fellow) and US (EACOA fellow). He joined SHAO in 2019, and became a full professor in 2022. He currently serves as the principle investigators (PI) of several large survey programs at the JCMT (SCOPE, SPACE) and ALMA (ALMASOP, ALMA-ATOMS/QUARKS), leading an international team including more than 160 experts to systematically investigate the star formation process in widely different Galactic environments.
