Kinetic temperature of massive star-forming molecular clumps measured with formaldehyde VI. The photodissociation region M17SW
X. Zhao, X. D. Tang, C. Henkel +20
The kinetic temperature structure of the photodissociation region M17SW was mapped using the IRAM 30 m telescope. This mapping employed the para-H2CO triplet (J(KaKc) = 303-202, 32…
Molecular Clouds at the Edge of the Galaxy II. Physical properties and scaling relations
C. S. Luo, X. D. Tang, C. Henkel +22
The outer Galaxy presents an optimal setting for investigating molecular clouds and star formation in environments with low metallicity. A total of 72 Galactic edge clouds were sur…
Dynamic Massive Star Formation: Radio Flux Variability in UCHII Regions
A. Y. Yang, M. A. Thompson, J. S. Urquhart +7
Context: Theoretical models of early accretion during the formation process of massive stars have predicted that HII regions exhibit radio variability on timescales of decades. How…
Kinetic temperature of massive star-forming molecular clumps measured with formaldehyde V. The massive filament DR21
X. Zhao, X. D. Tang, C. Henkel +18
The kinetic temperature structure of the massive filament DR21 has been mapped using the IRAM 30 m telescope. This mapping employed the para-HCO triplet ( = 3$_…
