Aims. This paper studies the cosmological power spectrum (PS) of the differential and integral galaxy volume number densities, respectively γi and γ i , constructed with the cosmological distances di (i = A, G, L, Z), where dA is the angular diameter distance, dG is the galaxy area distance, dL is the luminosity distance and dz is the redshift distance. Theoretical and observational quantities were obtained in the Friedmann-Lemaı̂tre-Robertson-Walker (FLRW) spacetime with a non-vanishing… Expand
