The Observations of Redshift Evolution in Large Scale Environments

The ORELSE survey is a wide-field survey dedicated to studying galaxy evolution across the full range of local environments with extensive photometric and spectroscopic observations of multiple well-known galaxy overdensities at z ~ 1. Recently, we move to higher redshift universe. The goal is to study the cluster evolution by linking these proto-Large Scale Structures (LSSs) to LSSs at z~1. To be continued.
