The Mass Spectra of Cores in Turbulent Molecular Clouds and Implications for the Initial Mass Function
Javier Ballesteros-Paredes, Adriana Gazol, Jongsoo Kim +4
We investigate the core mass distribution (CMD) resulting from numerical models of turbulent fragmentation of molecular clouds. In particular we study its dependence on the sonic r…
Density Power Spectrum of Compressible Hydrodynamic Turbulent Flows
Jongsoo Kim, Dongsu Ryu
Turbulent flows are ubiquitous in astrophysical environments, and understanding density structures and their statistics in turbulent media is of great importance in astrophysics. I…
Three-Dimensional Numerical Simulations of Thermal-Gravitational Instability in Protogalactic Halo Environment
Chang Hyun Baek, Hyesung Kang, Jongsoo Kim +1
We study thermal-gravitational instability in simplified models for protogalactic halos using three-dimensional hydrodynamic simulations. The simulations followed the evolution of…
Amplification of Interstellar Magnetic Fields and Turbulent Mixing by Supernova-Driven Turbulence Part II - The Role of Dynamical Chaos
D. S. Balsara, J. S. Kim
In this paper we further advance the study of magnetic field amplification in the interstellar medium that was started in Balsara et al (2004, Paper I). We show that the flux growt…
The pressure distribution in thermally bistable turbulent flows
Adriana Gazol, Enrique Vazquez-Semadeni, Jongsoo Kim
We present a systematic numerical study of the effect of turbulent velocity fluctuations on the thermal pressure distribution in thermally bistable flows. The simulations employ a…
