Optical Spectroscopy of Luminous Infrared Galaxies II. Analysis of the Nuclear and long-Slit Data
A spectroscopic survey of a sample of 201 luminous IRAS galaxies was caried out using the Palomar 5-meter amd University of Hawaii 2.2-m telescopes.
Comparisons and physics basis of tokamak transport models and turbulence simulations
The predictions of gyrokinetic and gyrofluid simulations of ion-temperature-gradient (ITG) instability and turbulence in tokamak plasmas as well as some tokamak plasma thermal transport models, which… Expand
Kinetic effects of energetic particles on resistive MHD stability.
We show that the kinetic effects of energetic particles can play a crucial role in the stability of the m/n=2/1 tearing mode in tokamaks (e.g., JET, JT-60U, and DIII-D), where the fraction of… Expand
Massively Parallel Three-Dimensional Toroidal Gyrokinetic Flux-Tube Turbulence Simulation
A massively parallel three-dimensional nonlinear gyrokinetic flux-tube simulation model is discussed. This simulation is used to study turbulent heat transport in core tokamak fusion plasmas. This… Expand
Computational modeling of fully ionized magnetized plasmas using the fluid approximation
Strongly magnetized plasmas are rich in spatial and temporal scales, making a computational approach useful for studying these systems. The most accurate model of a magnetized plasma is based on a… Expand
Large-scale gyrokinetic turbulence simulations: Effects of profile variation*
Two common computational domains used in gyrokinetic turbulence simulations are a local flux-tube and a global whole plasma volume. The effect of a radially varying pressure gradient is found to… Expand
Extended magnetohydrodynamic simulations of field reversed configuration formation and sustainment with rotating magnetic field current drive
Three-dimensional simulations of field reversed configuration (FRC) formation and sustainment with rotating magnetic field (RMF) current drive have been performed with the NIMROD code [C. R. Sovinec… Expand
Preliminary Simulations of FLR Effects on RFP Tearing Modes
Preliminary simulations of finite Larmor radius (FLR) effects on m = 1 tearing instabilities in a reverse field pinch (RFP) plasma are presented. δ f particle-in-cell (PIC) simulations were performed… Expand
A detailed study of kinetic effects of energetic particles on resistive MHD linear stability
The effects of energetic particles on MHD instabilities is a key issue in the basic physics that will be important in burning plasma experiments such as ITER. Recently, experiments (JET, JT-60U and… Expand
