GMC Collisions As Triggers of Star Formation. VIII. The Core Mass Function
Chia-Jung Hsu, Jonathan C. Tan, Duncan Christie +2
Compression in giant molecular cloud (GMC) collisions is a promising mechanism to trigger formation of massive star clusters and OB associations. We simulate colliding and non-coll…
GMC Collisions as Triggers of Star Formation. VII. The Effect of Magnetic Field Strength on Star Formation
Benjamin Wu, Jonathan C. Tan, Duncan Christie +1
We investigate the formation of stars within giant molecular clouds (GMCs) evolving in environments of different global magnetic field strength and large-scale dynamics. Building u…
GMC Collisions as Triggers of Star Formation. VI. Collision-Induced Turbulence
Benjamin Wu, Jonathan C. Tan, Fumitaka Nakamura +2
We investigate collisions between giant molecular clouds (GMCs) as potential generators of their internal turbulence. Using magnetohydrodynamic (MHD) simulations of self-gravitatin…
GMC Collisions As Triggers of Star Formation. IV. The Role of Ambipolar Diffusion
Duncan Christie, Benjamin Wu, Jonathan C. Tan
We investigate the role of ambipolar diffusion (AD) in collisions between magnetized giant molecular clouds (GMCs), which may be an important mechanism for triggering star cluster…
The Interstellar Medium and Star Formation of Galactic Disks. I. ISM and GMC properties with Diffuse FUV and Cosmic Ray Backgrounds
Qi Li, Jonathan C. Tan, Duncan Christie +2
We present a series of adaptive mesh refinement (AMR) hydrodynamic simulations of flat rotation curve galactic gas disks with a detailed treatment of the interstellar medium (ISM)…
GMC Collisions as Triggers of Star Formation. III. Density and Magnetically Regulated Star Formation
Benjamin Wu, Jonathan C. Tan, Duncan Christie +3
We study giant molecular cloud (GMC) collisions and their ability to trigger star cluster formation. We further develop our three dimensional magnetized, turbulent, colliding GMC s…
GMC Collisions as Triggers of Star Formation. II. 3D Turbulent, Magnetized Simulations
Benjamin Wu, Jonathan C. Tan, Fumitaka Nakamura +3
We investigate giant molecular cloud (GMCs) collisions and their ability to induce gravitational instability and thus star formation. This mechanism may be a major driver of star f…
Do Lognormal Column-Density Distributions in Molecular Clouds Imply Supersonic Turbulence?
K. Tassis, D. A. Christie, A. Urban +4
Recent observations of column densities in molecular clouds find lognormal distributions with power-law high-density tails. These results are often interpreted as indications that…
Formation of Interstellar Clouds: Parker Instability with Phase Transitions
Telemachos Ch. Mouschovias, Matthew W. Kunz, Duncan A. Christie
We follow numerically the nonlinear evolution of the Parker instability in the presence of phase transitions from a warm to a cold HI interstellar medium in two spatial dimensions.…
