Michael Bradley

Michael Bradley is a Professor in the Department of Physics at Umeå universitet. He serves as the Head of the General Relativity research group, which focuses on studying gravitational phenomena in rotating stars, perturbation theory in cosmology, and the interplay between gravity and matter in kinetic descriptions. His research includes analyzing solutions for rotating star interiors, gravitational wave propagation in cosmological models, and density fluctuations influenced by cosmological constants.

His research group explores topics such as the matching of internal and external gravitational fields of rotating stars, invariant classification methods for spacetime metrics, and quantum kinetic theory applications in cosmological particle formation. Bradley’s work bridges theoretical frameworks with observational implications in astrophysics and cosmology.

Publications span journals like Physical Review D, Classical and Quantum Gravity, and General Relativity and Gravitation, reflecting his contributions to cosmological models, perturbation analysis, and relativistic astrophysics. No notable scientific awards are explicitly mentioned, though his sustained academic output indicates significant contributions in his field.

Bradley collaborates with researchers such as Philip Semrén, Mats Forsberg, and Zoltán Keresztes, focusing on fluid dynamics in cosmology and gravitational wave studies. His research group’s work is supported by Umeå University’s Department of Physics infrastructure.
