New spectroscopic confirmations of high-redshift galaxy clusters
L. F. Olsen, E. Zucca, S. Bardelli +5
We present new spectroscopic data in the field of five high-redshift (z>=0.6) candidate galaxy clusters, drawn from the EIS Cluster Candidate Catalog. A total of 327 spectra were o…
Multi-object spectroscopy of low redshift EIS clusters. III. Properties of optically selected clusters
L. F. Olsen, C. Benoist, L. da Costa +2
We have carried out an investigation of the properties of low redshift EIS clusters using both spectroscopy and imaging data. We present new redshifts for 738 galaxies in 21 ESO Im…
The origin of X-ray emission of two distant (z>1) cluster candidate with XMM-Newton
D. M. Neumann, M. Arnaud, C. Benoist +8
We present here a study of XMM-Newton data of two distant galaxy cluster candidates. One of these was discovered serendipitously in near infrared data, CL J0533-2411, the other one…
ESO Imaging Survey. Deep Public Survey: Infrared Data for the Chandra Deep Field South
B. Vandame, L. F. Olsen, H. E. Jorgensen +12
This paper presents new J and Ks near-infrared data obtained from observations of the Chandra Deep Field South (CDF-S) conducted at the ESO 3.5m New Technology Telescope (NTT). The…
ISO far-infrared observations of rich galaxy clusters II. Sersic 159-03
L. Hansen, H. E. Jorgensen, H. U. Norgaard-Nielsen +3
The far-infrared emission from rich galaxy clusters is investigated. Maps have been obtained by ISO at 60, 100, 135, and 200 microns using the PHT-C camera. Ground based imaging an…
Confirming EIS Clusters. Optical and Infrared Imaging
L. F. Olsen, H. E. Jorgensen, M. Scodeggio +6
Clusters of galaxies are important targets in observationally cosmology, as they can be used both to study the evolution of the galaxies themselves and to constrain cosmological pa…
