Cosmology

This research seeks a deeper understanding of the various challenges confronting theoretical physics, ranging from combining quantum mechanics and gravity including cosmology to the phenomenology of particle physics. Researchers are using a many-pronged approach and insight gained from existing concepts like holography, developing a deeper mathematical understanding including new tools in field theory and string theory, building models beyond the Standard Model in order to address open questions in particle physics, and making proposals to improve the sensitivity of experiments to new physics. The recent detections of gravitational waves have revealed an invisible part of the universe that tests our understanding of black hole physics, neutron stars, and general relativity.
