报告摘要/Abstract
Our understanding about how stars, in particular massive star, form in molecular clouds is still limited. We are performing a comprehensive survey of Cygnus-X, which is the most massive and active giant molecular cloud complex within 3 kpc from the Sun. Based on observations with the SMA, Jansky VLA, JCMT, IRAM-30m, Herschel, Spitzer, and Shanghai Tianma radio telescope, we carry out a systemic study of the hierarchy of molecular cloud structures and star formation activities within the complex, aimed at constraining initial conditions of (massive) star formation and probing detailed mass assmbly processes which lead to the birth of star clusters. I will introduce the progress of the project, including a complete survey of dense gas structures over ~30 deg^2 sky coverage and their mass function, fragmentation, and dynamical properties. I may also talk about our ALMA and NOEMA observations of the selected targets from the survey.


报告人介绍/Bio:
Prof. Keping Qiu did his PhD thesis research as a pre-doctorial fellow at the Harvard-Smithsonian Center for Astrophysic from 2006 to 2009, and then worked in Max-Planck Institute for Radioastronomy as a postdoc fellow from 2010 to 2012. Prof. Qiu joined the School of Astronomy and Space Science, Nanjing University in late 2012. His research interests include star formation, molecular spectroscopy, dust polarization, HI survey of our Galaxy, and submm to radio interferometry.
