Linear filament and nested cluster evolution tomography (LANCET) I. Capture the evolution of dense gas in 14-parsec filament G316.8
Fengwei Xu, Ke Wang, Nicola Schneider +12
A dynamic view of mass assembly is essential for understanding the formation of massive stars and clusters. Interpreting evolutionary diagnostics from Galactic-wide surveys, howeve…
Galactic Large-scale Filaments Resident in Asymmetric Environments: Clues from Cross-filament Profiles of Density and Temperature
Keyun Su, Ke Wang, Fengwei Xu +1
Large-scale filaments ubiquitously exist in the Galactic interstellar medium, and their radial profiles offer insights into their formation mechanisms. We present a statistical ana…
The Structure of an 80 pc Long Massive Filament
Qian-Ru He, Won-Ju Kim, Gary A. Fuller +11
Using new Institut de Radioastronomie Millimétrique (IRAM) 30m telescope , =1-0 and Atacama Pathfinder Experiment (APEX) telescope and $…
Dual-band Unified Exploration of Three CMZ Clouds (DUET). Cloud-wide census of continuum sources showing low spectral indices
Fengwei Xu, Xing Lu, Ke Wang +19
The Milky Way's Central Molecular Zone (CMZ) is measured to form stars 10 times less efficiently than in the Galactic disk, based on emission from high-mass stars. However, the CMZ…
Massive Star Formation Starts in Sub-virial Dense Clumps Unless Resisted by Strong Magnetic Fields
Ke Wang, Yueluo Wang, Fengwei Xu
The initial conditions are critical for understanding high-mass star formation, but are not well observed. Built on our previous characterization of a Galaxy-wide sample of 463 can…
The Formation of Milky Way "Bones": Ubiquitous HI Narrow Self-Absorption Associated with CO Emission
Shenglan Sun, Ke Wang, Xunchuan Liu +1
Long and skinny molecular filaments running along Galactic spiral arms are known as "bones", since they make up the skeleton of the Milky Way. However, their origin is still an ope…
