Galaxy Cosmological Mass Function
Amanda R. Lopes, Alvaro Iribarrem, Marcelo B. Ribeiro +1
We study the galaxy cosmological mass function (GCMF) in a semi-empirical relativistic approach using observational data provided by galaxy redshift surveys. Starting from the theo…
Radial Density Statistics of the Galaxy Distribution and the Luminosity Function
Alvaro S. Iribarrem, Marcelo B. Ribeiro, William R. Stoeger
This paper discusses a connection between the relativistic number counts of cosmological sources and the observed galaxy luminosity function (LF). Observational differential number…
Finding a Spherically Symmetric Cosmology from Observations in Observational Coordinates -- Advantages and Challenges
M. E. Araujo, W. R. Stoeger
One of the continuing challenges in cosmology has been to determine the large-scale space-time metric from observations with a minimum of assumptions -- without, for instance, assu…
The Evolution of Our Local Cosmic Domain: Effective Causal Limits
G. F. R. Ellis, W. R. Stoeger
The causal limit usually considered in cosmology is the particle horizon, delimiting the possibilities of causal connection in the expanding universe. However it is not a realistic…
Inhomogeneous universes in observational coordinates
Roy Maartens, Neil Humphreys, David Matravers +1
Isotropic inhomogeneous dust universes are analysed via observational coordinates based on the past light cones of the observer's galactic worldline. The field equations are reduce…
LIMITS ON ANISOTROPY AND INHOMOGENEITY FROM THE COSMIC BACKGROUND RADIATION,
Roy Maartens, George F. R. Ellis, William R. Stoeger
We consider directly the equations by which matter imposes anisotropies on freely propagating background radiation, leading to a new way of using anisotropy measurements to limit t…
