Hub-filament systems and the growth of massive stars: episodic accretion, clustered environments, and projection effects
Dana Makarova, Dana Alina, Paolo Padoan +4
The processes controlling the early mass growth of future massive stars remain poorly understood, particularly the connection of this growth to star clustering and hub-filament sys…
The Milky Way Atlas for Linear Filaments III: Giant filaments and magnetic fields as evidence of a bubbly Galactic disk
Naval K. Bhadari, Ke Wang, Shu-ichiro Inutsuka +1
Linear filamentary structures are fundamental constituents of the interstellar medium and play a central role in star formation. Their relative orientation with respect to the ambi…
Discovery of a Compact Hub-Filament System in G286.21+0.17 with JWST and ALMA: Insights into Protocluster Formation and Competitive Accretion
L. K. Dewangan, N. K. Bhadari, Ram K. Yadav +17
We present a multi-wavelength study of the massive protocluster G286.21+0.17 (G286) using \emph{JWST} near-infrared imaging and ALMA HCO(1--0) observations. The \emph{…
The ALMA-QUARKS Survey: Evidence of an Explosive Molecular Outflow in IRAS 15520--5234
Ariful Hoque, Tapas Baug, Estrella Guzman +25
We present a study of the massive protocluster IRAS 155205234, which displays evidence of an explosive molecular outflow that unleashed a kinetic energy of at least 10 er…
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 ALMA-QUARKS survey: Hot Molecular Cores are a long-standing phenomenon in the evolution of massive protostars
Dezhao Meng, Tie Liu, Jarken Esimbek +34
We present an analysis of the QUARKS survey sample, focusing on protoclusters where Hot Molecular Cores (HMCs, traced by CH3CN(12--11)) and UC HII regions (traced by H30α/H40α) c…
