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…
Multi-object spectroscopy of low redshift EIS clusters. I
L. Hansen, L. F. Olsen, H. E. Jorgensen
We report the results of the first multi-object spectroscopic observations at the Danish 1.54m telescope at La Silla, Chile. Observations of five cluster candidates from the ESO Im…
An adaptive filter for the PLANCK Compact Source Catalogue construction
L. -Y. Chiang, H. E. Jorgensen, I. P. Naselsky +3
We develop a linear algorithm for extracting extragalactic point sources for the Compact Source Catalogue of the upcoming PLANCK mission. This algorithm is based on a simple top-ha…
Asymmetry of the PLANCK antenna beam shape and its manifestation in the CMB data
L. -Y. Chiang, P. R. Christensen, H. E. Jorgensen +4
We present a new method to extract the beam shape incorporated in the pixelized map of CMB experiments. This method is based on the interplay of the amplitudes and phases of the si…
