Abstract:
In order to investigate the formation and evolution of massive galaxies and their 
relation to underlying massive dark matter halos in the early universe, we have 
conducted unprecedentedly wide and deep $\lambda$ 1.1 mm imaging surveys of 
submillimeter galaxies (SMGs) using the bolometer camera AzTEC mounted on the 
submillimeter wave telescope ASTE in Northern Chile. The total coverage of the 
survey area exceeds a few deg$^2$ with a typical noise level of 0.7 mJy, that is 
deep enough to uncover ULIRG-class dusty violent starbursts lying $z>1$. Major 
blank fields, such as Subaru XMM Newton Deep Field (SXDF), Subaru Deep Field (SDF), 
AKARI Deep Field South (ADF-S), GOODS-S, and COSMOS, have been extensively observed, 
and $\sim$ 40 over density regions traced by high-$z$ radio galaxies and clusters 
of optically selected galaxies such as LAEs and LABs have also been mapped. In this 
paper, the emphasis will be placed on the on-going efforts and planned future programs 
on the multi-wavelengths analysis of SMGs based on follow-up observations using 
ground-based optical and infrared telescopes. Particularly, we will focus on the 
latest results on SSA22, SXDF, and SDF. Some of the selected results from southern 
clusters and blank fields like Bullet cluster and ADF-S, where Gemini-S must play 
unique roles for the multi-wavelengths investigation, will also be reviewed.
