Technique for separating velocity and density contributions in spectroscopic data and its application to studying turbulence and magnetic fields
Ka Ho Yuen, Ka Wai Ho, Alex Lazarian
Based on the theoretical description of Position-Position-Velocity(PPV) statistics in Lazarian & Pogosyan(2000), we introduce a new technique called the Velocity Decomposition Algo…
Magnetic Field Morphology in Interstellar Clouds with the Velocity Gradient Technique
Yue Hu, Ka Ho Yuen, Victor Lazarian +6
Magnetic fields, while ubiquitous in many astrophysical environments, are challenging to measure observationally. Based on the properties of anisotropy of eddies in magnetized turb…
Obtaining magnetic field strength using differential measure approach and velocity channel maps
Alex Lazarian, Ka Ho Yuen, Dmitri Pogosyan
We introduce two new ways of obtaining the strength of plane-of-sky (POS) magnetic field by simultaneous use of spectroscopic Doppler-shifted lines and the information on magnetic…
Velocity Gradient in the Presence of Self-Gravity: Identifying Gravity-induced Inflow and Determining Collapsing Stage
Yue Hu, Alex Lazarian, Ka Ho Yuen
Understanding how star formation is regulated requires studying the energy balance between turbulence, magnetic fields, stellar feedback, and gravity within molecular clouds. Howev…
Curvature of magnetic field lines in compressible magnetized turbulence: Statistics, magnetization predictions, gradient curvature, modes and self-gravitating media
Ka Ho Yuen, A. Lazarian
Magnetic field lines in interstellar media have a rich morphology, which could be characterized by geometrical parameters such as curvature and torsion. In this paper, we explore t…
A Synergy of the Velocity Gradients Technique and the Probability Density Functions for Identifying Gravitational Collapse in Self-Absorbing Media
Yue Hu, A. Lazarian
The Velocity Gradients Technique (VGT) and the Probability Density Functions (PDFs) of mass density are tools to study turbulence, magnetic fields, and self-gravity in molecular cl…
