SIMPLIFI -- Study of Interstellar Magnetic Polarization: a Legacy Investigation of Filaments. I. Magnetically-Guided Accretion onto the DR21 Ridge
Thushara G. S. Pillai, Jens Kauffmann, Juan D. Soler +15
We present first results from SIMPLIFI (Study of Interstellar Magnetic Polarization: a Legacy Investigation of Filaments), a SOFIA/HAWC+ polarimetric survey of Galac…
The converging gas flow around the infrared dark cloud G28.3
H. Beuther, C. Gieser, H. Linz +7
Aims: The G28.37+0.07 star-forming region is a prototypical infrared dark cloud (IRDC) located at the interface of a converging gas flow. This study characterizes the properties of…
ALMAGAL V. Relations between the core populations and the parent clump physical properties
D. Elia, A. Coletta, S. Molinari +54
Context. The fragmentation of massive molecular clumps into smaller, potentially star-forming cores plays a key role in the processes of high-mass star formation. The ALMAGAL proje…
Impact of gravity on changing magnetic field orientations in a sample of massive protostellar clusters observed with ALMA
Qizhou Zhang, Junhao Liu, Lingzhen Zeng +12
The magnetic field is integral to our understanding of the formation and dynamical evolution of molecular clouds and star formation within. We present a polarimetric survey of 17 m…
Faint absorption of the ground state hyperfine-splitting transitions of hydroxyl at 18 cm in the Galactic Disk
M. R. Rugel, H. Beuther, J. D. Soler +15
The interstellar hydride hydroxyl (OH) is a potential tracer of CO-dark molecular gas. We present new absorption line observations of OH at 18-cm wavelength towards four continuum…
On the relation between magnetic field strength and gas density in the interstellar medium: A multiscale analysis
D. J. Whitworth, S. Srinivasan, R. E. Pudritz +19
The magnetic field strength to gas density relation in the interstellar medium is of fundamental importance. We present and compare Bayesian analyses of the B-n relation for two co…
