1207.2542 (Alvaro S. Iribarrem et al.)

Radial Density Statistics of the Galaxy Distribution and the Luminosity Function    [PDF]

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 densities are defined and obtained from published LF data using such connection. We observe a distortion in the observational quantities that increases with higher redshift values as compared to the theoretical predictions. The use of different cosmological distance measures plays a role in such a distortion
