Gravity from Particle Amplitudes
Measurements of gravitational waves by the LIGO/Virgo and upcoming detectors open up the exciting possibility of testing theories of gravity, including the regime of strong gravity as probed by black holes just prior to merging. Analytical advances are required in order to push theory to the level where it can provide best-fit templates from which physical parameters can be extracted from data. To this end, our group develops and implements ideas and methods from quantum field theory, and especially from particle scattering amplitudes.
Gravity from Particle Amplitudes is a research group based at the Niels Bohr International Academy and affiliated with the Theoretical Particle Physics and Cosmology group at the Niels Bohr Institute, University of Copenhagen. Our interdisciplinary research builds on the two pillars of theoretical physics in gravity and particle physics.
