Funded Activity Summary

Precision cosmic expansion in the era of gravitational-wave astronomy. The disagreement in the size of the cosmic expansion rate, between measurements from local galaxy indicators and predictions from the early Universe, is a crisis for cosmology. This Project aims to resolve this situation using recent scientific breakthroughs in both observations and theory. We will optimise expansion measurements from the standard sirens discovered by gravitational-wave astronomy by accurate modelling of the cosmic velocity field which limits this analysis. And we will use recent breakthoughs in numerical general relativity to explore the influence of space-time curvature variations on these measurements. We will hence improve our understanding of the most important parameter describing the Universe, and its physics.
