ALMA observations of Magnetic Fields in the Massive Star-forming Region IRAS 18360-0537
Shixian Mo, Keping Qiu, Qizhou Zhang +6
Assessing the significance of magnetic fields in high-mass star formation remains one of the most challenging topics in astrophysics. In this study, we present full polarization ob…
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…
Digging into the Interior of Hot Cores with ALMA (DIHCA). VI. The Formation of Low-mass Multiple Systems in High-mass Cluster-forming Regions
Qiuyi Luo, Patricio Sanhueza, Stella S. R. Offner +14
Most stars form in multiple systems, with profound implications in numerous astronomical phenomena intrinsically linked to multiplicity. However, our knowledge about the process on…
Magnetic threads and gravity: ALMA Observations of IRDC G14.225-0.506
Nacho Añez-López, Gemma Busquet, Josep Miquel Girart +14
During the star formation process, the interplay between gravity, turbulence, and B-fields is significant, with B-fields apparently serving a regulatory function. However, the exte…
Deep Andromeda JCMT-SCUBA2 Observations. The Submillimeter Maps and Giant Molecular Clouds
Sihan Jiao, Jingwen Wu, Hauyu Baobab Liu +23
We have carried out unprecedentedly deep, nearly confusion-limited JCMT-SCUBA2 mapping observations on the nearest spiral galaxy, M31 (Andromeda). The 850 m image with a …
Magnetic Fields in Massive Star-forming Regions (MagMaR). VI. Magnetic Field Dragging in the Filamentary High-mass Star-forming Region G35.20--0.74N due to Gravity
Jihye Hwang, Patricio Sanhueza, Josep Miquel Girart +27
We investigate the magnetic field orientation and strength in the massive star-forming region G35.20-0.74N (G35), using polarized dust emission data obtained with the Atacama Large…
