John Baker (L2IT) About a decade after the first detection of gravitational waves with ground-based observatories in 2015, the European Space Agency has recently adopted a bold mission to realize a space-based gravitational-wave mission. The expanse of space provides a profoundly quiet environment and room for the kind of gargantuan instrument needed to listen to […]
Rungployphan (Om) Kieokaew (IRAP) Cosmic plasmas drive dynamical processes throughout the universe, from magnetic field generation to explosive energy conversion. Magnetized plasmas in the solar system are the most accessible environments for in-situ measurements. Unlike theoretical or numerical simulation approaches, where assumptions about plasma behavior must be made a priori (i.e., on large, fluid-like, or […]
