CITA Postdoctoral Fellow James Beattie Wins Hubble Fellowship to Decipher the Origin of Magnetic Fields in the Early Universe

March 25, 2026

Dr. James Beattie, Postdoctoral Fellow at the Canadian Institute for Theoretical Astrophysics and Princeton University, was awarded a prestigious Hubble Fellowship, announced the on behalf of NASA today.

This fellowship will allow him to build the next generation of supercomputer models to probe how the early Universe may have become magnetized by the first stellar explosions, and how some of the strongest magnetic fields in merging compact objects are created. Dr. Beattie will carry out this groundbreaking research at the Institute for Advanced Study in Princeton, beginning in the fall of 2026.

The NASA Hubble Fellowship Program (NHFP) supports highly promising postdoctoral scientists pursuing independent research that contributes to NASA Astrophysics through theory, observation, experimentation, or instrument development. The NASA Hubble Fellowship represents one of the highest early-career honors in astrophysics.

Once selected, fellows are assigned to one of three sub-categories corresponding to NASA’s “big questions” about the cosmos:

• How Does the Universe Work?– Einstein Fellows
• How Did We Get Here?– Hubble Fellows
• Are We Alone?– Sagan Fellows

Selected as a Hubble Fellow, James aims to uncover the universal laws governing energy and magnetic fields in turbulent cosmic environments. His research will span an extraordinary range of conditions, from galaxy-wide, blast wave–driven turbulence and violent mergers of compact objects to controlled laboratory plasma experiments. Using advanced GPU-powered simulations, he will investigate how the first stellar explosions (supernovae) may have sparked the Universe’s earliest magnetic fields. He will also develop sophisticated non-ideal, relativistic models of merging stars to understand how the strongest magnetic fields in the known Universe form, while advancing astrophysical turbulence modeling on exascale supercomputers.

½Û×ÓÊÓƵ Dr. James Beattie
James earned his Ph.D. in astrophysics in early-2024, from the Australian National University (ANU) before joining the Canadian Institute for Theoretical Astrophysics (CITA) and Princeton University as a joint postdoctoral researcher. His research focuses on the intersection of fluid dynamics, high-performance computing, magnetic fields, and plasma-astrophysics specifically doing pioneering work on how supersonic, magnetized turbulence shapes the interstellar medium. Dr. Beattie recently led the creation of the world’s highest-resolution simulation of magnetized turbulence, an achievement that earned him the prestigious HPCwire Editor’s Choice Award for “Top HPC-Enabled Scientific Achievement.” Throughout his time at CITA, James has been an engaged member of the community, who brought complex theoretical plasma physics to life through cutting-edge digital visualization.

Please join us in congratulating Dr. Beattie on this outstanding achievement and wishing him the best as he takes his next steps at the IAS!
