Astrophysical shocks or bursts from a photoionizing source can disturb the typical collisional plasma found in galactic interstellar media or the intergalactic medium. The spectrum emitted by this plasma contains diagnostics that have been used to determine the time since the disturbing event, although this determination becomes uncertain as the elements in the plasma return to ionization equilibrium. A general solution for the equilibrium timescale for each element arises from the elegant… Expand

The Role of Diffusive Shock Acceleration on Nonequilibrium Ionization in Supernova Remnant Shocks. II. Emitted Spectra
We present a grid of nonequilibrium ionization models for the X-ray spectra from supernova remnants undergoing efficient diffusive shock acceleration. The calculation follows the hydrodynamics of theExpand
A Lagrangian scheme for time-dependent ionization in simulations of astrophysical plasmas
TLDR
This work reports a FORTRAN program that performs fast non-equilibrium ionization calculations in post-processing based on hydrodynamics or magnetohydrodynamic simulation results, and introduces an adaptive time-step strategy to improve the computational efficiency. Expand
Non-equilibrium ionization by a periodic electron beam. I. Synthetic coronal spectra and implications for interpretation of observations
Context. Coronal heating is currently thought to proceed via the mechanism of nanoflares, small-scale and possibly recurring heating events that release magnetic energy. Aims. We investigate theExpand
Measurements of ion velocity separation and ionization in multi-species plasma shocks
The ion velocity structure of a strong collisional shock front in a plasma with multiple ion species is directly probed in laser-driven shock-tube experiments. Thomson scattering of a 263.25 nm probeExpand
X-ray Signatures of Non-equilibrium Ionization Effects in Galaxy Cluster Accretion Shock Regions
The densities in the outer regions of clusters of galaxies are very low, and the collisional timescales are very long. As a result, heavy elements will be under-ionized after they have passed throughExpand
Ion–neutral Interactions and Nonequilibrium Ionization in the Solar Chromosphere
The thermal structure of the chromosphere is regulated through a complex interaction of various heating processes, radiative cooling, and the ionization degree of the plasma. Here we study the impactExpand
THREE-DIMENSIONAL SIMULATIONS OF THE THERMAL X-RAY EMISSION FROM YOUNG SUPERNOVA REMNANTS INCLUDING EFFICIENT PARTICLE ACCELERATION
Supernova remnants (SNRs) are believed to be the major contributors to Galactic cosmic rays. The detection of non-thermal emission from SNRs demonstrates the presence of energetic particles, butExpand
Shock Waves in Supernova Ejecta
Astrophysical shock waves are a major mechanism for dissipating energy, and by heating and ionizing the gas they produce emission spectra that provide valuable diagnostics for the shock parameters,Expand
Nonequilibrium Ionization Effects on Solar EUV and X-Ray Imaging Observations
During transient events such as major solar eruptions, the plasma can be far from the equilibrium ionization state because of rapid heating or cooling. Non-equilibrium ionization~(NEI) is importantExpand
UNRAVELING THE ORIGIN OF OVERIONIZED PLASMA IN THE GALACTIC SUPERNOVA REMNANT W49B
Recent observations have shown several supernova remnants (SNRs) have overionized plasmas, where ions are stripped of more electrons than they would be if in equilibrium with the electronExpand
