TL;DR: The experimental data are in closer agreement with simulations using the model of Stewart and Pyatt and an alternative due to Ecker and Kröll suggested by recent x-ray free-electron laser experiments is suggested.

TL;DR: In this paper , the authors achieved a burning-plasma state in the laboratory using a strategy to increase the spatial scale of the capsule through two different implosion concepts and showed that fusion self-heating in excess of the mechanical work injected into the implosions, satisfying several burningplasma metrics.

TL;DR: The first direct measurements of total absorption of short laser pulses on solid targets in the ultrarelativistic regime are reported, showing an enhanced absorption at intensities above 10(20) W/cm(2), reaching 60% for near-normal incidence and 80%-90% for 45 degrees incidence.

TL;DR: A charge exchange emission model is developed that successfully reproduces the soft x-ray spectrum of comet Linear C/1999 S4, observed with the Chandra X-ray Observatory.

TL;DR: Using the SuperEBIT electron beam ion trap, the 2s(1/2)-2p( 1/2) transitions in U88+ and U89+ are measured and the available precision is improved by nearly an order of magnitude.
