Astrophysics

Astrophysics research investigates the dynamics of plasmas, turbulence, magnetic fields, and high-energy phenomena across the universe. We develop theoretical and computational approaches to study astrophysical turbulence, magnetohydrodynamics, dynamo processes, gravitational waves, and cosmic magnetic fields, with strong emphasis on nonlinear phenomena and large-scale numerical simulations.
