Magnetic Field Morphology in Interstellar Clouds with the Velocity Gradient Technique

23 Feb 2020 Hu Yue Yuen Ka Ho Lazarian Victor Ho Ka Wai Benjamin Robert A. Hill Alex S. Lockman Felix J. Goldsmith Paul F. Lazarian Alex

Magnetic fields, while ubiquitous in many astrophysical environments, are challenging to measure observationally. Based on the properties of anisotropy of eddies in magnetized turbulence, the Velocity Gradient Technique is a method synergistic to dust polarimetry that is capable of tracing plane-of-the-sky magnetic field, measuring the magnetization of interstellar media and estimating the fraction of gravitational collapsing gas in molecular clouds using spectral line observations...
