Can we avoid dark energy?
J. P. Zibin, A. Moss, D. Scott
The idea that we live near the centre of a large, nonlinear void has attracted attention recently as an alternative to dark energy or modified gravity. We show that an appropriate…
Gauging the cosmic microwave background
J. P. Zibin, Douglas Scott
We provide a new derivation of the anisotropies of the cosmic microwave background (CMB), and find an exact expression that can be readily expanded perturbatively. Close attention…
The cosmic variance of Omega
T. P. Waterhouse, J. P. Zibin
How much can we know about our Universe? All of our observations are restricted to a finite volume, and therefore our estimates of presumably global cosmological parameters are nec…
Scalar Perturbations on Lemaitre-Tolman-Bondi Spacetimes
J. P. Zibin
In recent years there has been growing interest in verifying the horizon-scale homogeneity of the Universe that follows from applying the Copernican Principle to the observed isotr…
