Understanding the Hot Solar Corona via X-ray Observations with NuSTAR Abstract: NuSTAR is a highly sensitive direct-focusing hard x-ray (HXR) observatory optimized to observe astrophysical sources. In certain conditions, NuSTAR can also observe the Sun – and characterize faint x-ray emission from sources… Read More

The distribution of Birkeland currents in time and space Abstract: Birkeland currents communicate information between the magnetopause and the rest of the magnetosphere, flowing along magnetic field lines at Earth. These currents which underpin solar wind-magnetosphere-ionosphere coupling, and are… Read More
