Astrophysical Plasma Theory

The group focuses on developing reliable models of complex astrophysical systems to understand the origins of energetic particles, such as cosmic rays, their radiative signatures and their role in our Galaxy and beyond

We explore the physical processes that govern particle acceleration and dynamics, plasma physics, and radiative signatures in different scenarios, guided by theory, simulations, laboratory experiments, and observations. Our work includes studying supernova remnants, massive stellar clusters, extra-galactic jets, and gamma-ray bursts to address the multi-scale challenge of understanding how particles are energized to extreme values in the Universe. We also develop and utilize advanced plasma simulation techniques to capture the relevant energy and length scales of astrophysical systems. We do this in close collaboration with our colleagues in the Non-thermal Astrophysics Division
