Evidence for the Helicity Barrier from Measurements of the Turbulence Transition Range in the Solar Wind Data from NASA's Parker Solar Probe reveal that a barrier to the transfer of energy often forms in the solar wind, limiting energy reaching small scales and helping explain why solar wind protons are ...

New paper in @physrevx.bsky.social from Jack McIntyre @qmspaceplasma.bsky.social, providing evidence from #ParkerSolarProbe for the existence of the helicity barrier in the solar wind, which may alter how turbulence heats space and astrophysical plasmas journals.aps.org/prx/abstract...

Magnetosheath Jets Associated With a Solar Wind Rotational Discontinuity in a Hybrid‐Vlasov Simulation We conduct a 2D hybrid-Vlasov simulation of the interaction between Earth's bow shock and a solar wind rotational discontinuity Magnetosheath jets that form during the shock-discontinuity interac...

My latest paper, regarding magnetosheath jet formation associated with a solar wind rotational discontinuity, is now published!

Jets were recently found at Mars, and we made a statistical study, using data from the Maven spacecraft, to find out more about them. You may read the paper here: doi.org/10.1051/0004...

Jets Downstream of Collisionless Shocks: Recent Discoveries and Challenges - Space Science Reviews Plasma flows with enhanced dynamic pressure, known as magnetosheath jets, are often found downstream of collisionless shocks. As they propagate through the magnetosheath, they interact with the surrou...

Our review paper on downstream jets is out! We summarize findings from 100s of articles on how jets form at collisionless shocks, their role in planetary systems, and their space weather effects. Many questions remain to explore! Read it here: link.springer.com/article/10.1...
