modeling of Galactic dust polarized CMB foreground
Alexei G. Kritsuk, Ka Wai Ho, Ka Ho Yuen +1
We present the analysis of high-resolution synthetic dust polarization maps derived from large-scale simulations of magnetized multiphase interstellar turbulence carried out with t…
Statistical signatures of interstellar turbulence in dust polarization maps
Ka Wai Ho, Ka Ho Yuen, Raphael Flauger +1
We present results from a high-resolution interstellar turbulence simulation and show that it closely reproduces recent measurements. Our model captures the scaling of $EE…
The stable "Unstable Natural Media" due to the presence of turbulence
Ka Wai Ho, Ka Ho Yuen, Alex Lazarian
The term "unstable neutral media" (UNM) has traditionally been used to describe the transient phase formed between the warm and cold neutral hydrogen (HI) phases and has not been t…
Sub-Alfvenic Turbulence: Magnetic to Kinetic Energy Ratio, Modification of Weak Cascade and Implications for Magnetic Field Strength Measurement
Alex Lazarian, Ka Wai HO, Ka Ho Yuen +1
We study the properties of sub-Alfvenic magnetohydrodynamic (MHD) turbulence, i.e., turbulence with Alfven Mach number , where is the velocity at the injection…
Applying the Velocity Gradient Technique in NGC 1333: Comparison with Dust Polarization Observations
Archana Soam, Ka Ho Yuen, Ian Stephens +3
Magnetic fields (B-fields) are ubiquitous in the interstellar medium (ISM), and they play an essential role in the formation of molecular clouds and subsequent star formation. Howe…
Cosmic Ray Feedback on Bi-stable ISM Turbulence
Roark Habegger, Ka Wai Ho, Ka Ho Yuen +1
While cosmic rays are well coupled to a galaxy's interstellar medium (ISM) at scales of , adjusting stratification and driving outf…
