STUDIES (SCUBA-2 Ultra Deep Imaging EAO Survey)
STUDIES is a multi-year JCMT Large Program, to obtain extremely deep submillimeter images of the distant universe. The goal is to understand the origin of the far-infrared cosmic background radiation and the history of the cosmic star formation. Buy detecting a large sample of faint distant dusty galaxies that give rise to the far-infrared background, we can study when and where most of the stars in the universe form, and how these affect the evolution of galaxies. The figure shows the STUDIES 450 micron image of the center of the COSMOS survey field, using the data collected during the first year of STUDIES observations. It detects nearly 100 faint galaxies (small circles) at high significance levels, and is the deepest 450 micron image by far.
