Deciphering Solar Particle Mysteries

Congratulations to Dr David Long from the School of Physical Sciences who has received €608,460 to investigate the origins of solar energetic particles. His project, SEP Origins, examines how giant shock waves in the Sun’s atmosphere accelerate particles to near-light speeds—a process that can disrupt satellite and communication systems on Earth.

The research explores the hypothesis that small-scale solar flares, known as "campfires," provide the initial energy boost required for these particles to be captured by larger shock waves. Understanding this "spark" is critical for predicting and mitigating the impact of solar events on our global infrastructure.

"As these particles flood the solar system, they have significant implications for our near-Earth systems," explained Dr David Long. "Understanding how and where this energisation occurs is vital for our ability to predict and mitigate the effects of energetic particle events."
