Recovering 3D Magnetic Turbulence from Single-Frequency Faraday Screens

Aliaksandr Melnichenka, Alex Lazarian, Dmitri Pogosyan

Statistics of polarized synchrotron radiation carry information about the properties of the underlying turbulence. Different statistical measures constructed from observables probe…

Gradient Technique Theory: Tracing magnetic field and obtaining magnetic field strength

Alex Lazarian, Ka Ho Yuen, Dmitri Pogosyan

The gradient technique is a promising tool with theoretical foundations based on the fundamental properties of MHD turbulence and turbulent reconnection. Its various incarnations u…

Nature of Striation in 21 cm Channel Maps: Velocity Caustics

Yue Hu, A. Lazarian, D. Alina +2

The alignment of striated intensity structures in thin neutral hydrogen (HI) spectroscopic channels with Galactic magnetic fields has been observed. However, the origin and nature…

Magnetic field strength from turbulence theory (I): Using differential measure approach (DMA)

A. Lazarian, Ka Ho Yuen, Dmitri Pogosyan

The mean plane-of-sky magnetic field strength is traditionally obtained from the combination of polarization and spectroscopic data using the Davis-Chandrasekhar-Fermi (DCF) techni…

Velocity Centroids Anisotropy and the Signature of different MHD Modes in the Turbulent ISM

D. Hernández-Padilla, A. Esquivel, A. Lazarian +3

Magnetic turbulence is anisotropic as the directions of motion are constrained by the magnetic field. Such anisotropy can be observed in velocity centroids obtained from spectrosco…

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…
