The Fields, Astrophysics and Spacetime Theory (FAST) group at Utah State
University is actively involved in the study of the most fundamental
physics that underlies the fabric of the Cosmos. We study the theoretical
underpinnings of gravitation and
theory, and research how astrophysics plays a
role in illuminating these theoretical frameworks.
Our theoretical research includes explorations of conformal and scale invariant gravity theories and unified field theories, classical and quantum dynamics of the gravitational field, symmetries and conservation laws in relativistic field theories, Lagrangian and Hamiltonian formulation of field theory, and geometrical methods in mathematical physics.
Our astrophysics research explores how gravitational wave astronomy is changing our view of the Cosmos, and how observations of the Universe in gravity can illuminate the fundamental structure of gravitational theory itself. Our work includes simulation of galaxies and binary star systems, extraction of science results from analysis and signal processing of gravitational wave data, and laser interferometer characterization.
