Coronal mass ejections, jets, prominence eruptions: solar eruptions are an active field with a broad range of accepted phenomena, and an even broader range of proposed mechanisms that cause the phenomena. This talk reports the observations of an event that connects the major eruption classes, and could provide a holistic explanation for all of...

It is challenging to capture kinetic phenomena in global simulations due to the significant difference between the kinetic scales and global scales. The magnetohydrodynamics with embedded particle-in-cell model (MHD-EPIC) is developed to incorporate kinetic physics into global simulations.

Magnetic flux ropes are bundles of twisted magnetic fields and their associated currents. They are common on the surface of the sun (and presumably all other stars) and are observed to have a large range of sizes and lifetimes. Two “kink” unstable ropes are generated in a background plasma in the Large Plasma Device at UCLA. When they collide...

The TRACERS mission consists of two identically instrumented satellites in the same low-Earth, sun-synchronous orbit with the spacecraft separated by 10-120s along the orbital track. The mission was selected for implementation  in June, 2019 by NASA as a Small Explorer class investigation.

Whistler waves are a common feature of space plasmas, notably present upstream of shocklets, SLAMS, and switchbacks in the solar wind. In the laboratory, they have been studied for at least 60 years, being easily generated from RF antennas, electron beams, and in pulsed power experiments.

The interaction of an object within a streaming fluid is a phenomenon widely encountered in physics, spanning a range of length scales, from the familiar meter- to cm-sized wakes observed behind rocks in flowing streams (Fig. 1a), the kilometers-long wakes observed in cloud patterns as air flows past ocean islands (Fig.
