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


Statistical physics for cosmic structures
The recent observations of galaxy and dark matter clumpy distributions have provided new elements to the understanding of the problem of cosmological structure formation. The strong clumpingExpand
The FORS Deep Field
Dedicating a major fraction of its guaranteed time, the FORS consortium started investigating a FORS Deep Field, which also contains a known QSO at z = 3.36. The FORS Deep Field (FDF) was imaged inExpand
