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…
HST Observations of the QSO pair Q1026-0045A,B
Patrick Petitjean, Jean Surdej, Alain Smette +3
The spatial distribution of the Ly forest is studied using new HST data for the quasar pair Q~1026--0045 A and B at = 1.438 and 1.520 respectively. The angular separati…
The Evolution of Radio-loud Quasars at High Redshift
I. M. Hook, P. A. Shaver, R. G. McMahon
We present results from two surveys for radio-loud quasars. These are (1) a northern survey reaching S(5GHz)=0.2Jy and (2) the Parkes QSO survey reaching S(2.7GHz)=0.25Jy, which to…
The Redshift Cutoff and the Quasar Epoch
P. A. Shaver, I. M. Hook, C. A. Jackson +2
We have obtained complete redshift information for a sample of 442 radio-loud quasars with flux densities S(11cm) >= 0.25Jy. These come from a completely-identified sample of 878 f…
