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=…
Probing the Cosmic Large-Scale Structure with the REFLEX Cluster Survey : Profile of an ESO Key Programme
H. Böhringer, L. Guzzo, C. A. Collins +11
The paper describes the goals and first results of the ROSAT ESO Flux-Limited X-ray (REFLEX) Cluster Survey, a redshift survey of the X-ray brightest galaxy clusters in the ROSAT A…
Results from the REFLEX Cluster Survey
H. Böhringer, L. Guzzo, C. A. Collins +11
Based on the ROSAT All-Sky Survey we have conducted a large redshift survey as an ESO key programme to identify and secure redshifts for the X-ray brightest clusters found in the s…
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…
