Predictive gyrokinetic simulations matched TCV edge plasma data
This research indicates that full-f global gyrokinetic simulations can use only magnetic geometry, heating power, and particle inventory to reproduce key edge-plasma features and compare reasonably well with measurements in Tokamak á Configuration Variable discharge #65125.

Cold ions enable ion-acoustic waves in asymmetric reconnection
This research indicates that ion-acoustic waves can appear in asymmetric magnetopause reconnection when cold ions are present, and that these waves help transfer energy between particle species.

VLBI and Gaia DR3 give broadly similar LPV astrometry
This research indicates that VLBI and Gaia DR3 parallaxes for 43 Galactic long period variable stars are generally consistent within uncertainties for about half the sample, with Gaia DR3 values tending to be slightly smaller and VLBI becoming more effective for nearer stars beyond about 500 pc.

Time-resolved measurements track heating and ionization in dense plasmas
This research indicates that time-resolved resonant X-ray measurements can diagnose heating and ionization dynamics in solid-density plasmas and help constrain models of high-intensity laser interactions.
