论文摘要
我们介绍了在Alma Band 7中偶然检测到的56个来源样本的详细表征，这是ALMA大型计划的一部分，该计划在宇宙和ECDF中研究了CII（ALPINE）。这些来源已用于得出总红外光度函数（LF），并估计宇宙恒星形成速率密度（SFRD）至z = 6。我们已经在所有可用的多波长和光度红移目录以及更深层次的近乎IR源列表和地图中寻找对应物，以识别公共目录中没有匹配项的光学深色源。我们的ALMA盲目调查使我们能够进一步推动高Z尘土星系的性质和演变，从而确定了发光和庞大的巨大来源，以通过任何远红外调查从未探测过红移和微弱的亮度。高山数据是第一个采样红外LF的微弱末端的数据，显示从z = 2.5到z = 6的进化很少，而平坦的坡度达到了最高的红移。通过整合亮度函数获得的SFRD在z = 2和6之间几乎保持恒定，并且显着高于光学/紫外线衍生物，显示出尘土高的星系和遮挡的恒星形成至High-Z的重要贡献。大约14％的高山偶然性连续源是光学+近IR黑暗（六个仅在MID-IR中显示出对应物，没有HST或近IIR鉴定，而两个在z = 5时被检测到[CII]发射器。具有MID-IR对应物的六个HST和近红外星系在Z = 5时贡献了总SFRD的17％，并在Z> 3处主导了恒星质量函数的高质量端。
We present the detailed characterisation of a sample of 56 sources serendipitously detected in ALMA band 7, as part of the ALMA Large Program to INvestigate CII at Early Times (ALPINE) in COSMOS and ECDFS. These sources have been used to derive the total infrared luminosity function (LF) and to estimate the cosmic star formation rate density (SFRD) up to z=6. We have looked for counterparts in all the available multi-wavelength and photometric redshift catalogues, and in deeper near- and mid-IR source lists and maps, to identify optically dark sources with no matches in the public catalogues. Our ALMA blind survey allows us to push further the study of the nature and evolution of dusty galaxies at high-z, identifying luminous and massive sources to redshifts and faint luminosities never probed before by any far-infrared surveys. The ALPINE data are the first ones to sample the faint-end of the infrared LF, showing little evolution from z=2.5 to z=6, and a flat slope up to the highest redshifts. The SFRD obtained by integrating the luminosity function remains almost constant between z=2 and 6, and significantly higher than the optical/UV derivations, showing an important contribution of dusty galaxies and obscured star formation up to high-z. About 14 per cent of the ALPINE serendipitous continuum sources are optically+near-IR dark (six show a counterpart only in the mid-IR and no HST or near-IR identification, while two are detected as [CII] emitters at z=5). The six HST and near-IR dark galaxies with mid-IR counterpart contribute for about 17 per cent of the total SFRD at z=5 and dominate the high-mass end of the stellar mass function at z>3.
