Low cosmic-ray ionisation at parsec scales in G035.39-00.33
Andrea Socci, Ashley Barnes, Jaime Pineda +11
Cosmic rays (CRs) regulate the chemical evolution of the gas and its coupling to the magnetic field in the densest and coldest regions of the interstellar medium (ISM). However, th…
SiO emission in the filamentary Infrared Dark Cloud G035.39-00.33: An ALMA view
Rong Liu, Izaskun Jiménez-Serra, Giuliana Cosentino +8
Filamentary infrared dark clouds (IRDCs) are believed to represent the initial conditions for massive star and cluster formation. We investigate the IRDC G035.39-00.33 using SiO, H…
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…
The SOFIA Massive (SOMA) Star Formation Q-band Follow-up. II. Hydrogen Recombination Lines Toward High-Mass Protostars
Prasanta Gorai, Kotomi Taniguchi, Jonathan C. Tan +11
Hydrogen recombination lines (HRLs) are valuable diagnostics of the physical conditions in ionized regions around high-mass stars. Understanding their broadening mechanisms and int…
The SOMA-POL Survey. I. Polarization and magnetic field properties of massive protostars
Tuva Källberg, Chi Yan Law, Jonathan C. Tan +2
The role of magnetic fields in regulating the formation of massive stars remains much debated. Here we present sub-millimeter polarimetric observations with JCMT-POL2 at m…
The SOFIA Massive (SOMA) Star Formation Survey. V. Clustered Protostars
Zoie Telkamp, Ruben Fedriani, Jonathan C. Tan +16
We present m SOFIA-FORCAST images of seven regions of ``clustered" star formation as part of the SOFIA Massive (SOMA) Star Formation Survey. We identify a total of 34…
