ORELSE

Observations of Redshift Evolution in Large Scale Environments

Overview

The ORELSE survey is a systematic search for large-scale structures around an original sample of 20 galaxy clusters in a redshift range of 0.6 < z < 1.3 with the field of view of all fields ∼0.25–0.5 deg². The ORELSE survey is dedicated to study galaxy evolution across the full range of local and global environments with extensive photometric and spectroscopic observations at z ~ 1.
