Velocity gradients key to explaining large-scale magnetic field structure

All celestial bodies — planets, suns, even entire galaxies — produce magnetic fields, affecting such cosmic processes as the solar wind, high-energy particle transport, and galaxy formation. Small-scale magnetic fields are generally turbulent and chaotic, yet large-scale fields are organized, a phenomenon that plasma astrophysicists have tried explaining for decades, unsuccessfully.  In a paper published …

Francis Halzen wins 2026 APS Medal for Exceptional Achievement in Research

Welcome, Prof. Joshua Foster!

Joshua Foster’s long-standing interest in computational tools is, he believes, what led him to research a range of theoretical physics, including dark matter, gravitational waves, and new physics. “What got me interested in studying theoretical physics in particular was the idea that you could study structures or ways of doing calculations that would enable you …
