Fig. 1. Schematic diagram of highly charged muonic argon ions observed in this study. μAr 16+, μAr 15+, and μAr 14+ bind one, two, or three electrons, respectively, in addition to negative muons.

Initial analysis of the image uncovered hundreds of planetary nebulae in the Sculptor galaxy, a glowing shell of ionized gas left in the wake of dying stars like our Sun. “Beyond our galactic ...

In an underwater streamer discharge, plasma channels are created and propagate in water. After the discharge, the ionized gas channels gradually cool down and decay. In this paper, a time-resolved ...
