Abell 521: Dynamical analysis of a young cluster
S. Maurogordato, D. Proust, T. C. Beers +5
We present the results of a dynamical analysis of the rich X-Ray luminous galaxy cluster Abell 521, and discuss the nature of the arc-like structure first noted by Maurogordato et…
The ESO Slice Project (ESP) Galaxy Redshift Survey. VII. The Redshift and Real-Space Correlation Functions
L. Guzzo, J. G. Bartlett, A. Cappi +17
We present analyses of the two-point correlation properties of the ESP galaxy redshift survey. From the redshift-space correlation function xi(s), we see positive clustering out to…
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=…
Biasing and high-order statistics from the SSRS2
C. Benoist, A. Cappi, L. N. da Costa +3
We analyze different volume-limited samples extracted from the Southern Sky Redshift Survey (SSRS2), using counts-in-cells to compute the Count Probability Distribution Function (C…
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…
Is the Universe a fractal? Results from the SSRS2
A. Cappi, C. Benoist, L. N. da Costa +1
We perform a fractal analysis of the Southern Sky Redshift Survey 2, following the methods prescribed by Pietronero and collaborators, to check their claim that the galaxy distribu…
