Abstract

There are three major axes to describe the evolution of galaxies, namely, time (redshift), space (environment) and mass (stellar mass). In this article, one topic each will be presented along these axes. (1) Based on the Subaru wide-field (30') optical imaging of two distant clusters (z=0.55 and 0.83), we show the large scale structures in galaxy distributions on a scale greater than 10 Mpc, which serve as an evidence for hierarchical growth of rich clusters of galaxies through assembly of surrounding groups. (2) Based on the deep NIR imaging of high-z clusters at z similar to 1 and 1.5, we show massive galaxies in clusters have assembled most of their mass by z = 1.5, which is earlier than the hierarchical model predictions. (3) Based on the Subaru deep and wide optical imaging of Subaru/XMM-Newton Deep Survey Field, we show a deficit of red and faint galaxies and a lack of blue massive galaxies in. the high density regions at z similar to 1, which suggest down-sizing in galaxy formation as apparently opposed to the CDM-based bottom-up scenario.
