Chandra X-ray Observations of Newly Discovered, z ~ 1 Clusters from the Red-Sequence Cluster Survey
Amalia Hicks, Erica Ellingson, Mark Bautz +3
Observational studies of cluster evolution over moderate redshift ranges (to z ~ 1) are a powerful tool for constraining cosmological parameters, yet a comprehensive knowledge of t…
EXPLORE/OC: A Search for Planetary Transits in the Field of NGC 2660
Kaspar von Braun, Brian Lee, Gabriela Mallen-Ornelas +3
We present preliminary photometric results of a monitoring study of the open cluster NGC 2660 as part of the EXPLORE/OC project to find planetary transits in Galactic open clusters…
The Red-Sequence Cluster Survey: first lensing results
Henk Hoekstra, H. K. C. Yee, Michael D. Gladders
The Red-Sequence Cluster Survey (RCS) is a 100 deg^2 galaxy cluster survey designed to provide a large sample of optically selected clusters of galaxies with redshifts 0.1<z<1.4. T…
The Red-Sequence Cluster Survey: The Value of and
Michael D. Gladders, H. K. C. Yee
The Red-Sequence Cluster Survey (RCS) is a 100 deg optical survey for high-redshift galaxy clusters. One of the goals of the survey is a measurement of and via the…
Star Formation and Galaxy Environment
H. K. C. Yee
The dependence of star formation rate on galaxian environment is a key issue in the understanding of galaxy formation and evolution. However, the study of this subject is complex a…
Photometric Properties of Low Redshift Galaxy Clusters
W. A. Barkhouse, H. K. C. Yee, O. Lopez-Cruz
We have recently completed a comprehensive photometric survey of 27 Abell clusters with the 8k mosaic camera on the KPNO 0.9m telescope. Preliminary luminosity functions and dwarf-…
