Filamentary Dust Polarization and the Morphology of Neutral Hydrogen Structures

Autor: Halal, George, Clark, Susan E., Cukierman, Ari, Beck, Dominic, Kuo, Chao-Lin

Publikováno v: ApJ 961 29 (2024)

Filamentary structures in neutral hydrogen (HI) emission are well aligned with the interstellar magnetic field, so HI emission morphology can be used to construct templates that strongly correlate with measurements of polarized thermal dust emission.
