Invited Presentation

Surveys of Clumps, Cores, and Condensations in Cygnus-X

Presenter: Keping Qiu (Nanjing University)

The formation of massive stars remains poorly understood. We have been performing a comprehensive survey of massive star formation in 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 65m radio telescope, we carry out a systemic study of the hierarchy of molecular cloud structures in the complex, aimed at understanding the assembly of gas into stars on various scales, and to what extent high-mass protostars acquire mass in a way similar to their low-mass counterparts. I will introduce the progress of the survey and preliminary results, as well as an outlook of future observations.
