- Abstract: We present the survey design, data reduction, construction of images, and source catalog of the Atacama Large Millimeter/submillimeter Array (ALMA) twenty-six arcmin 2 survey of GOODS-S at one millimeter (ASAGAO). ASAGAO is a deep (1 σ depth ∼ 61 μJy beam −1 for a 250 kλ-tapered map with a synthesized beam size of 0${^{\prime\prime}_{.}}$ 51 × 0${^{\prime\prime}_{.}}$ 45) and wide area (26 arcmin 2 ) survey on a contiguous field at 1.2 mm. By combining with ALMA archival data in the GOODS-South field, we obtained a deeper map in the same region (1 σ depth ∼ 30 μJy beam −1 for a deep region with a 250 kλ-taper, and a synthesized beam size of 0${^{\prime\prime}_{.}}$ 59 × 0${^{\prime\prime}_{.}}$ 53), providing the largest sample of sources (25 sources at ≥5.0 σ, 45 sources at ≥4.5 σ) among ALMA blank-field surveys to date. The number counts show that $52^{+11}_{-8}$ % of the extragalactic background light at 1.2 mm is resolved into discrete sources at S 1.2 mm > 135 μJy. We create infrared (IR) luminosity functions (LFs) in the redshift range of $z$ = 1–3 from the ASAGAO sources with K s -band counterparts, and constrain the faintest luminosity of the LF at 2.0 < $z$ < 3.0. The LFs are consistent with previous results based on other ALMA and SCUBA-2 observations, which suggest a positive luminosity evolution and negative density evolution with increasing redshift. We find that obscured star-formation of sources with IR luminosities of log ( L IR / L ⊙ ) ≳ 11.8Abstract: We present the survey design, data reduction, construction of images, and source catalog of the Atacama Large Millimeter/submillimeter Array (ALMA) twenty-six arcmin 2 survey of GOODS-S at one millimeter (ASAGAO).
