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…
