TL;DR
This deep 1.1 mm survey of the AKARI Deep Field South with AzTEC/ASTE identified 198 sources, constraining number counts and the contribution to the cosmic infrared background, and estimating their role in cosmic star formation and stellar mass buildup.
Contribution
First deep and wide 1.1 mm survey of ADF-S providing the largest source catalog and tightest constraints on faint source counts and their cosmic contributions.
Findings
198 sources detected at 3.5-15.6 sigma significance.
1.1 mm sources with flux >=1 mJy contribute 12-16% to the CIB.
Estimated 20% of present-day stellar mass formed by these sources at z >= 1.
Abstract
We present results of a 1.1 mm deep survey of the AKARI Deep Field South (ADF-S) with AzTEC mounted on the Atacama Submillimetre Telescope Experiment (ASTE). We obtained a map of 0.25 sq. deg area with an rms noise level of 0.32-0.71 mJy. This is one of the deepest and widest maps thus far at millimetre and submillimetre wavelengths. We uncovered 198 sources with a significance of 3.5-15.6 sigma, providing the largest catalog of 1.1 mm sources in a contiguous region. Most of the sources are not detected in the far-infrared bands of the AKARI satellite, suggesting that they are mostly at z ~ 1.5 given the detection limits. We constructed differential and cumulative number counts in the ADF-S, the Subaru/XMM Newton Deep Field (SXDF), and the SSA 22 field surveyed by AzTEC/ASTE, which provide currently the tightest constraints on the faint end. The integration of the best-fit number counts…
