: A High-Performance 3D MHD and Multifluid Dust Code Written in a Dynamic Language with an Interactive Human-AI Development Framework

Ka Wai Ho

We present , a new finite-volume code for compressible hydrodynamics and magnetohydrodynamics, written in Julia and primarily designed for GPU systems. The code so…

The cosmic ray ionization rate from H3+ observations can be overestimated due to neglect of time-dependent chemistry

Ka Wai Ho, Munan Gong, Kedron Silsbee +1

The cosmic ray ionization rate (CRIR) is a key parameter governing the physical, chemical and thermal evolution of the interstellar medium. The primary technique for measuring the…

Tracing magnetic field in super-Alfvenic turbulence with Gradient Technique

Ka Wai Ho, Alex Lazarian

Super-Alfvenic turbulence is important for many astrophysical objects, particularly galaxy clusters. In this paper, we explore the accuracy of Synchrotron Intensity Gradients (SIGs…

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…

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…
