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…
Expanding Space: the Root of all Evil?
Matthew J. Francis, Luke A. Barnes, J. Berian James +1
While it remains the staple of virtually all cosmological teaching, the concept of expanding space in explaining the increasing separation of galaxies has recently come under fire…
Power Spectra to 1% Accuracy between Dynamical Dark Energy Cosmologies
Matthew J. Francis, Geraint F. Lewis, Eric V. Linder
For dynamical dark energy cosmologies we carry out a series of N-body gravitational simulations, achieving percent level accuracy in the relative mass power spectra at any redshift…
