cds-question@unistra.frmillimeter-astronomysubmillimeter-astronomyredshiftedWe present statistics of 133 faint 1.2mm continuum sources detected in about 120 deep Atacama Large Millimeter/submillimeter Array (ALMA) pointing data that include all the archival deep data available by 2015 June. We derive number counts of 1.2mm continuum sources down to 0.02mJy partly with the assistance of gravitational lensing, and find that the total integrated 1.2mm flux of the securely identified sources is 22.9_-5.6_^+6.7^Jy/deg2 which corresponds to 104_25_^+31^% of the extragalactic background light (EBL) measured by Cosmic Background Explorer observations. These results suggest that the major 1.2mm EBL contributors are sources with 0.02mJy, and that very faint 1.2mm sources with <~0.02mJy contribute negligibly to the EBL with the possible flattening and/or truncation of number counts in this very faint flux regime. To understand the physical origin of our faint ALMA sources, we measure the galaxy bias b_g_ by the counts-in-cells technique, and place a stringent upper limit of b_g_<3.5 that is not similar to b_g_ values of massive distant red galaxies and submillimeter galaxies but comparable to those of UV-bright, star-forming BzK galaxies (sBzKs) and Lyman break galaxies (LBGs). Moreover, in the optical and near-infrared (NIR) deep fields, we identify optical-NIR counterparts for 59% of our faint ALMA sources, the majority of which have luminosities, colors, and the IRX-{beta} relation the same as sBzKs and LBGs. We thus conclude that about a half of our faint ALMA sources are dust-poor, high-z galaxies as known as sBzKs and LBGs in optical studies, and that these faint ALMA sources are not miniature (U)LIRGs simply scaled down with the infrared brightness.2016ApJS..222....1Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/222/1CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVIII/95 : Herschel Multi-tiered Extragalactic Survey (Oliver+, 2012)J/ApJ/803/34 : z~4-10 galaxies from HST legacy fields (Bouwens+, 2015)J/MNRAS/442/577 : ALESS submm galaxies radio properties (Thomson+, 2014)J/ApJS/209/22 : SSDF survey: IRAC catalogs (Ashby+, 2013)J/ApJ/768/91 : ALMA observations of LESS submm galaxies (Hodge+, 2013)J/MNRAS/411/102 : AzTEC/ASTE 1.1mm observations in the ADF-S (Hatsukade+ 2011)J/ApJ/723/1678 : LensPerfect A1689 analysis (Coe+, 2010)J/MNRAS/401/160 : AzTEC survey of the SHADES fields.
