Tracing magnetic field morphology using the Velocity Gradient Technique in the presence of CO self-absorption
Cheng-Han Hsieh, Yue Hu, Shih-Ping Lai +5
Probing magnetic fields in self-gravitating molecular clouds are generally difficult even with the use of the polarimetry. Based on the properties of magneto-hydrodynamic (MHD) tur…
Statistical tracing of magnetic fields: comparing and improving the techniques
Ka Ho Yuen, Junda Chen, Yue Hu +9
Magnetohydrodynamic(MHD) turbulence displays velocity anisotropies which reflect the direction of the magnetic field. This anisotropy has led to the development of a number of stat…
Improving the Accuracy of Magnetic Field Tracing by Velocity Gradients: Principal Component Analysis
Yue Hu, Ka Ho Yuen, A. Lazarian
Tracing of the magnetic field with Velocity Gradient Technique (VGT) allows observers to probe magnetic field directions with spectroscopic data. In this paper, we employ the metho…
Distribution of velocity gradient orientations: Mapping magnetization with the Velocity Gradient Technique
A. Lazarian, Ka Ho Yuen, Ka Wai Ho +5
Recent developments of the Velocity Gradient Technique (VGT) show that the velocity gradients provide a reliable tracing of magnetic field direction in turbulent plasmas. In this p…
Gradients of Synchrotron Polarization: Tracing 3D distribution of magnetic fields
A. Lazarian, Ka Ho Yuen
We describe a new technique for probing galactic and extragalactic 2D and 3D magnetic field distribution using gradients of polarized synchrotron emission. The fluctuations of magn…
Advancing the Velocity Gradient Technique: Using Gradient Amplitudes and handling thermal broadening
Ka Ho Yuen, A. Lazarian
The recent development of the Velocity Gradient Technique allows observers to map magnetic field orientations and magnetization using the direction of velocity gradients. Aside fro…
