A theoretical prediction for the dipole in nearby distances using cosmography
Hayley J. Macpherson, Asta Heinesen
Cosmography is a widely applied method to infer kinematics of the Universe at small cosmological scales while remaining agnostic about the theory of gravity at play. Usually cosmol…

The Effect of Nonlinear Gravity on the Cosmological Background During Preheating
Ryn Grutkoski, Hayley J. Macpherson, John T. Giblin +1
We use numerical relativity to study the violent preheating era at the end of inflation. This epoch can result in highly nonlinear fluctuations in density and gravitational potenti…
