Abstract:
We report on the environmental dependence of properties of galaxies
around the RDCSJ0910+54 cluster at z=1.1. We obtained multi-band
wide-field images of the cluster with Suprime-Cam and MOIRCS on Subaru
and WFCAM on UKIRT. Also, an intensive spectroscopic campaign was
carried out using LRIS on Keck and FOCAS on Subaru. We collected 161
spectra with secure redshifts, with which we calibrated a larger
sample of photometric redshifts.
Description:
We made Suprime-Cam observations in R and z bands in May 2005.
Following this initial run, we carried out VRiz bands observations
with Suprime-Cam in November 2006, Ks-band observation with MOIRCS in
February 2006, and K-band observation with WFCAM in March 2007.
