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=…
Real and Redshift-Space Clustering in the ESP Galaxy Redshift Survey
L. Guzzo, J. G. Bartlett, A. Cappi
We discuss the two-point correlation properties of galaxies in the ESO Slice Project (ESP) redshift survey, both in redshift and real space. The redshift-space correlation function…
The Redshift and Real-Space Correlation Functions from the ESP Galaxy Redshift Survey
L. Guzzo, J. G. Bartlett, A. Cappi
We discuss the behaviour of the redshift- and real-space correlation functions from the ESO Slice Project (ESP) galaxy redshift survey. xi(s) for the whole survey is positive out t…
EISily looking for distant galaxy clusters
Catarina Lobo, Davide Lazzati, Angela Iovino +2
We present a new algorithm to search for distant clusters of galaxies on catalogues deriving from imaging data, as those of the ESO Imaging Survey. We discuss the advantages of our…
The ESO Slice Project (ESP) galaxy redshift survey IV. A discussion of systematic biases in galaxy redshift determinations
A. Cappi, G. Zamorani, E. Zucca +17
We present a detailed discussion of the redshift errors associated to the ESO Slice Project measurements. For a subsample of 742 galaxies with redshifts determined both from the ab…
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…
