Surveys of clumps, cores, and condensations in Cygnus X: Temperature and nonthermal velocity dispersion revealed by VLA NH3 observations
Xu Zhang, Keping Qiu, Qizhou Zhang +6
The physical properties, evolution, and fragmentation of massive dense cores (MDCs, 0.1 pc) are fundamental pieces in our understanding of high-mass star formation. We aim t…
Core mass function of a single giant molecular cloud complex with ~10^4 cores
Yue Cao, Keping Qiu, Qizhou Zhang +2
Similarity in shape between the initial mass function (IMF) and the core mass functions (CMFs) in star-forming regions prompts the idea that the IMF originates from the CMF through…
DR 21 South Filament: a Parsec-sized Dense Gas Accretion Flow onto the DR 21 Massive Young Cluster
Bo Hu, Keping Qiu, Yue Cao +8
DR21 south filament (DR21SF) is a unique component of the giant network of filamentary molecular clouds in the north region of Cygnus X complex. Unlike the highly fragmented and st…
Surveys of Clumps, Cores, and Condensations in Cygnus X: I. a New Catalog of ~0.1 pc Massive Dense Cores
Yue Cao, Keping Qiu, Qizhou Zhang +3
Using infrared to (sub)millimeter data from Spitzer, Herschel, the James Clerk Maxwell Telescope, and the IRAM 30-m telescope, we conducted an unbiased survey of the massive dense…
An Isothermal Outflow in High-mass Star-forming Region G240.31+0.07
Junhao Liu, Keping Qiu, Friedrich Wyrowski +4
We present Atacama Pathfinder EXperiment (APEX) observations toward the massive star-forming region G240.31+0.07 in the CO J = 3--2, 6--5, and 7--6 lines. We detect a parsec-sized,…
