A statistical study towards high-mass BGPS clumps with the MALT90 survey

Zhang, Chuan-Peng; Xu, Jin-Long; Liu, Xiao-Lan +2 more

In this work, we perform a statistical investigation towards 50 high-mass clumps using data from the Bolocam Galactic Plane Survey (BGPS) and Millimetre Astronomy Legacy Team 90-GHz survey (MALT90). Eleven dense molecular lines (N₂H⁺(1-0), HNC(1-0), HCO⁺(1-0), HCN(1-0), HN¹³C(1-0), H¹³CO^+…

Global photometric analysis of Galactic HII regions

Kirsanova, Maria S.; Topchieva, Anastasiia; Wiebe, Dmitri

Total infrared fluxes are estimated for 99 HII regions around massive stars. The following wavebands have been used for the analysis: 8 and 24 µm, based on data from the Spitzer Space Telescope (IRAC and MIPS, respectively); 70, 160, 250, 350 and 500 µm, based on data from the Herschel Space Observatory (PACS and SPIRE). The estimated …

Gas compression and likely triggered star formation in the infrared bubble N107

Yuan, Jing-Hua; Li, Jin-Zeng; Ren, Zhi-Yuan +2 more

The expansion of HII regions can regulate the evolution of their natal clouds and the star formation therein. Infrared dust bubbles, which are frequently associated with HII regions, are ideal laboratories to test whether impulse(s) driven by the expanding bubbles enhances or suppresses star-formation. In this work, we present a comprehensive stud…
