The Local Space Density of Optically-Selected Clusters of Galaxies
D. A. Bramel, R. C. Nichol, A. C. Pope
Abridged] We present here new results on the space density of rich, optically-selected, clusters of galaxies at low redshift (z<0.15). These results are based on the application of…
CFHT AO Imaging of the CLASS Gravitational Lens System B1359+154
D. Rusin, P. B. Hall, R. C. Nichol +3
We present adaptive optics imaging of the CLASS gravitational lens system B1359+154 obtained with the Canada-France-Hawaii Telescope (CFHT) in the infrared K band. The observations…
Spectroscopic Observations of Optically Selected Clusters of Galaxies from the Palomar Distant Cluster Survey
B. P. Holden, R. C. Nichol, A. K. Romer +4
We have conducted a redshift survey of sixteen cluster candidates from the Palomar Distant Cluster Survey (PDCS) to determine both the density of PDCS clusters and the accuracy of…
The CFH Optical PDCS Survey (COP): First results
C. Adami, B. Holden, A. Mazure +5
We present the first results of the COP survey about the reality of the PDCS clusters, about their velocity dispersions and dynamic and about the periodicity of the structures alon…
The Bright SHARC Survey: The X-ray Cluster Luminosity Function
R. C. Nichol, A. K. Romer, B. P. Holden +6
We present here initial results on the X-ray Cluster Luminosity Function (XCLF) from the Bright SHARC sample of distant X-ray clusters of galaxies. This sample is 97% complete in i…
