Topology of non-linear structure in the 2dF Galaxy Redshift Survey
J. Berian James, Matthew Colless, Geraint F. Lewis +1
We study the evolution of non-linear structure as a function of scale in samples from the 2dF Galaxy Redshift Survey, constituting over 221 000 galaxies at a median redshift of z=0…
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…
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…
The angular correlations of galaxies in the COSMOS field
H. J. McCracken, J. A. Peacock, L. Guzzo +21
We present measurements of the two-point galaxy angular correlation function w(θ) in the COSMOS field. Independent determinations of w(θ) as a function of magnitude limit are prese…
Type Ia supernova diversity: Standardizing the candles
T. M. Davis, J. B. James, B. P. Schmidt +1
Future use of type Ia supernovae for cosmology aims not only to determine the equation of state of dark energy, but also to constrain possible variations in its value. To achieve t…
