ABSTRACT

Stars form in dense regions within molecular clouds, called pre-stellar cores (PSCs), which provide information on the initial conditions in the process of star formation. The low dust temperature (nck Cold Clumps. "TOP", standing for "TRAO Observations of Planck cold clumps", aims at an unbiased CO/13CO survey of 2000 Planck Galactic Cold Clumps with the Taeduk Radio Astronomy Observatory 14-meter telescope. "SCOPE", standing for "SCUBA-2 Continuum Observations of Pre-protostellar Evolution", is a legacy survey using SCUBA-2 onboard of the James Clerk Maxwell Telescope (JCMT) at East Asia Observatory (EAO) to survey 1000 Planck galactic cold clumps at 850 micron. We are also actively developing follow-up observations with other ground-based telescopes (NRO 45-m, Effelsberg 100-m, IRAM 30-m. SMT, KVN, SOFIA, SMA, ALMA). We aim to statistically study the initial conditions of star formation and cloud evolution in various kinds of environments. I will present the progress and the future plans of this internationally collaborating project.

BIO
Dr. Tie Liu obtained his BSc degree from Department of Physics, Xiamen University in 2008. He then spent five-year’ time in Peking University earned the PhD degree 2013. After that, Dr. Tie Liu worked at Peking University and Universidad de Chile until April 2014. From June 2014, he did research in the Korea Astronomy and Space Science Institute (KASI) as a KASI fellow until June 2017. In July 2017, he started to work at East Asian Core Observatories Association (EACOA) as an EACOA fellow. His research is mainly focused on star formation in the Milky Way. He is now leading two internationally collaborating survey projects for observing thousands of Planck Galactic Cold clumps at the Taeduk Radio Astronomy Observatory (TRAO) and the James Clerk Maxwell Telescope (JCMT). The survey team (including ~150 people) is also actively developing follow-up observations with many other ground-based telescopes including the ALMA.
