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=…
Globular Clusters in Dwarf Elliptical Galaxies
B. W. Miller, H. C. Ferguson, J. Lotz +2
Globular clusters (GCs) provide one way of determining when the most important periods of star formation in dwarf elliptical (dE) galaxies occurred. Thus, they are also useful for…
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…
