Magnetic Fields in Massive Star-forming Regions (MagMaR). VII. On the dynamical importance of B-fields in massive protocluster W33 A
Fengwei Xu, Q. Zhang, P. Sanhueza +30
Magnetic fields (B-fields) are likely important in massive protocluster formation, but their role remains poorly constrained. We present 1.2 mm ALMA full-polarization observations…
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{…
Investigation of Hourglass-shaped Magnetic fields in the G35.20-0.74 Star-Forming Complex
O. R. Jadhav, L. K. Dewangan, A. K. Maity +7
To investigate the role of magnetic fields toward the G35N and G35S sub-regions in the G35.20-0.74 star-forming complex, we utilized multi-wavelength polarimetric observations from…
Unveiling an Hourglass-Shaped Magnetic Field toward IRDC G351.77-0.53
O. R. Jadhav, L. K. Dewangan, I. I. Zinchenko +5
We present the SOFIA/HAWC+ 214 m polarimetric observations toward the infrared dark cloud G351.77-0.53 (hereafter G351), complemented by existing multi-wavelength data sets. In…
Discovery of a rich population of compact hub-filament systems in a single star-forming complex
L. K. Dewangan, Ram K. Yadav, Saurabh Sharma +4
We report the discovery of 45 compact hub-filament systems (HFSs; median size 2.4 pc) in infrared-dark clouds (IRDCs) in the W33 complex, located at the junction of the Scutu…
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…
