The trouble with Hubble: Local versus global expansion rates in inhomogeneous cosmological simulations with numerical relativity
Hayley J. Macpherson, Paul D. Lasky, Daniel J. Price
In a fully inhomogeneous, anisotropic cosmological simulation performed by solving Einstein's equations with numerical relativity, we find a local measurement of the effective Hubb…

Einstein's Universe: Cosmological structure formation in numerical relativity
Hayley J. Macpherson, Daniel J. Price, Paul D. Lasky
We perform large-scale cosmological simulations that solve Einstein's equations directly via numerical relativity. Starting with initial conditions sampled from the cosmic microwav…
