Entropic Priors and Bayesian Model Selection
Brendon J. Brewer, Matthew J. Francis
We demonstrate that the principle of maximum relative entropy (ME), used judiciously, can ease the specification of priors in model selection problems. The resulting effect is that…
Fractal Bubble Cosmology: A concordant cosmological model?
Juliana Kwan, Matthew J. Francis, Geraint F. Lewis
The Fractal Bubble model has been proposed as a viable cosmology that does not require dark energy to account for cosmic acceleration, but rather attributes its observational signa…
Halo Mass Functions in Early Dark Energy Cosmologies
Matthew J. Francis, Geraint F. Lewis, Eric V. Linder
We examine the linear density contrast at collapse time, for large-scale structure in dynamical dark energy cosmologies, including models with early dark energy. Contrary to…
Can Early Dark Energy be Detected in Non-Linear Structure?
Matthew J. Francis, Geraint F. Lewis, Eric V. Linder
We present the first study of early dark energy cosmologies using N-body simulations to investigate the formation of non-linear structure. In contrast to expectations from semi-ana…
Cosmological Radar Ranging in an Expanding Universe
Geraint F. Lewis, Matthew J. Francis, Luke A. Barnes +2
While modern cosmology, founded in the language of general relativity, is almost a century old, the meaning of the expansion of space is still being debated. In this paper, the que…
Coordinate Confusion in Conformal Cosmology
Geraint F. Lewis, Matthew J. Francis, Luke A. Barnes +1
A straight-forward interpretation of standard Friedmann-Lemaitre-Robertson-Walker (FLRW) cosmologies is that objects move apart due to the expansion of space, and that sufficiently…
