The ALMA-QUARKS Survey: Properties of Hot Molecular Fragments in the Massive Protocluster IRAS 17233-3606
Li Chen, Sheng-Li Qin, Dongting Yang +29
To investigate the physical mechanisms of fragmentation within the hot molecular core of the massive protocluster IRAS 17233-3606 (G351.78-0.54), we carried out a detailed analysis…
Measuring Magnetic Field Strengths in Galactic Star-forming Regions via the Zeeman Effect with the SKA
Tyler L. Bourke, Tao-Chung Ching, Laura Fissel +14
Magnetic fields thread the interstellar medium from the largest to the smallest scales and play an important role in molecular cloud evolution and star formation. Quantifying this…
Evolution of starless cores in massive clumps seen by the ALMA ASHES and QUARKS surveys
Dongting Yang, Hong-li Liu, Sheng-li Qin +28
We present a systematic comparative analysis of 324 starless cores in early-phase infrared-dark clouds (IRDCs; ASHES survey) and evolved-phase infrared-bright clouds (IRBCs; QUARKS…
From inter-filamentary gas to filaments and hubs: gas flows in the Mon R2 hub-filament system
Jihye Hwang, Doris Arzoumanian, Yoshito Shimajiri +5
Hub-filament systems (HFSs) play an important role in the formation of massive stars and star clusters. Although the velocity structures along dense filaments have been studied, th…
Magnetic field Topology and Star Formation in the Cepheus B Filamentary cloud under External Feedback
Panigrahy Sandhyarani, Chakali Eswaraiah, Manash R. Samal +6
We present a detailed study of the Cep B molecular cloud based on sub-mm dust polarization and CO (J=3--2) spectral line observations obtained with SCUBA-2/POL-2 and HARP on…
The dominance of turbulence over magnetism in the formation of massive star cluster seeds
Junhao Liu, Patricio Sanhueza, Piyali Saha +32
High-mass stars form in protoclusters, where gravo-magnetic processes shape collapsing clouds and clumps to be elongated preferentially perpendicular to magnetic (B) fields. Yet it…
