Impact of inhomogeneous curvature on growth rate measurements from magnitude fluctuations
Andrew Nguyen, Chris Blake, Hayley J. Macpherson
Our interpretation of current cosmological observations rests on the assumptions of homogeneity and isotropy, leading to uniform background curvature and expansion characterised by…

On the potential for inhomogeneities to mimic an evolving dark energy
Hayley J. Macpherson, Georgios Valogiannis
In this work we explore the ability of inhomogeneities to result in an apparent dynamical evolution of dark energy. The idea that inhomogeneities may alter the expansion history of…

Large-scale weak lensing convergence in nonlinear general relativity
Hayley J. Macpherson
In this work we investigate the weak lensing convergence using an end-to-end nonlinear general relativistic framework. Combining numerical relativity simulations of large-scale str…
