The ESO Slice Project (ESP) galaxy redshift survey: VI Groups of Galaxies
M. Ramella, G. Zamorani, E. Zucca +17
In this paper we identify objectively and analyze groups of galaxies in the recently completed ESP survey. We find 231 groups above the number overdensity threshold delta(rho)/rho=…
The large-scale distribution of galaxies in the Shapley Concentration
S. Bardelli, E. Zucca, G. Zamorani
We present the results of a galaxy redshift survey in the central region of the Shapley Concentration. Our total sample contains ~2000 radial velocities of galaxies both in the clu…
The Luminosity Function and Mean Galaxy Density from the ESP galaxy Redshift Survey
E. Zucca, G. Zamorani, P. Vettolani
We summarise the main results obtained over the last two years by the ESO Slice Project (ESP) redshift survey, concerning the luminosity function and mean density of galaxies, and…
The ESO Slice Project [ESP] galaxy redshift survey: V. Evidence for a D=3 sample dimensionality
R. Scaramella, L. Guzzo, G. Zamorani +17
The issue of the approximate isotropy and homogeneity of the observable universe is one of the major topics in modern Cosmology: the common use of the Friedmann-Robertson-Walker [F…
