  1. Turbulent black hole coronae can produce observed X-ray spectra
    Simulations show turbulent black hole coronae generate two-temperature plasmas with extended nonthermal ion distributions while producing observed X-ray spectra.
  2. GVEC provides flexible 3D MHD equilibrium solutions
    GVEC solves 3D magnetohydrodynamic equilibrium equations for stellarators using flexible coordinates that represent complex plasma boundaries with simple cross-sections.
  3. Time-resolved X-ray probes track heating and ionization in solid-density plasma
    Sub-picosecond X-ray spectroscopy and multi-scale simulations reveal spatiotemporal heating and ionization dynamics in laser-driven plasmas, with implications for fusion energy models.
  4. Shock precursor type changes ion and electron acceleration
    Simulations reveal two distinct regimes in transrelativistic shocks where competing plasma instabilities produce dramatically different particle acceleration efficiencies for ions and electrons.
  5. Predictive gyrokinetic simulations matched TCV edge-plasma data
    Fully predictive gyrokinetic simulations of tokamak edge turbulence using Gkeyll validate against TCV experiments and reveal how negative triangularity enhances confinement through E×B flow shear.
  6. Cold ions enable ion-acoustic waves in asymmetric reconnection
    Particle-in-cell simulations characterize ion-acoustic wave excitation and energy transfer mechanisms in asymmetric magnetic reconnection with cold ion populations.
