X-ray and ultraviolet (UV) observations of the outer solar atmosphere have been used for
many decades to measure the fundamental parameters of the solar plasma. This review …

An emerging theme in modern astrophysics is the connection between astronomical
observations and the underlying physical phenomena that drive our cosmos. Both the …

The effects of cosmic-ray diffusion and radiative cooling on the structure of the Galactic wind
are studied using a steady-state approximation. It is known that realistic cooling processes …

Two new high-resolution X-ray spectroscopy missions, XRISM and Athena, will observe
deeper and with higher X-ray resolution than ever before possible. Interpreting these new X …

The hyperfine-induced 2 s 2 p 3 P 0→ 2 s 2 1 S 0 transition rate in Be-like sulfur was
measured by monitoring the decay of isotopically pure beams of 32 S 12+ and 33 S 12+ ions …

This review summarizes the present status of an ongoing experimental effort to provide
reliable rate coefficients for dielectronic recombination of highly charged iron ions for the …

A novel collisionless shock jump condition is suggested by modeling the entropy production
at the shock transition region. We also calculate downstream developments of the atomic …

Astrophysical X-ray spectroscopy promises huge potential scientific returns. The soft X-ray
bandpass, 0.1-10 keV, contains transitions from the K-, L-, and M-shell of every cosmically …

Dielectronic recombination (DR) is the major electron-ion recombination process in many
astrophysical and laboratory plasmas. This process has been thoroughly studied for several …

We report ionization cross section measurements for electron impact single ionization (EISI)
of Fe 11+ forming Fe 12+ and electron impact double ionization (EIDI) of Fe 11+ forming Fe …
