我们已经确定了无线电和/或中红外对应物的350个源中的198个，这些源位于钱德拉深场南部中心，位于250，350和500 μm处。我们将其中的114个对应物与具有先前导出的光度红移的光源进行了匹配，并将光谱能量分布与斯皮策太空望远镜获得的BLAST通量和70和160 μm处的通量进行了拟合。通过这种方式，我们已经限制了尘埃温度，总的远红外/亚毫米光度，和星星的形成率为每个源。我们的研究结果表明，平均而言，与在850 μm处进行的调查中检测到的亚毫米源相比，BLAST源位于显著较低的红移处，并且具有显著较低的静止框架尘埃温度。我们证明，在我们的样品中，由于选择效应，尘埃温度随红移而明显增加。最后，我们提供了完整的多波长目录中包含的105 σ BLAST源的完整的109 deg 2调查区域。
We have identified radio and/or mid-infrared counterparts to 198 out of 350 sources detected at ⩾5σ over ∼9 deg2 centered on the Chandra Deep Field South by the Balloon-borne Large Aperture Submillimeter Telescope (BLAST) at 250, 350, and 500 μm. We have matched 114 of these counterparts to optical sources with previously derived photometric redshifts and fitted spectral energy distributions to the BLAST fluxes and fluxes at 70 and 160 μm acquired with the Spitzer Space Telescope. In this way, we have constrained dust temperatures, total far-infrared/submillimeter luminosities, and star formation rates for each source. Our findings show that, on average, the BLAST sources lie at significantly lower redshifts and have significantly lower rest-frame dust temperatures compared to submillimeter sources detected in surveys conducted at 850 μm. We demonstrate that an apparent increase in dust temperature with redshift in our sample arises as a result of selection effects. Finally, we provide the full multiwavelength catalog of ⩾5σ BLAST sources contained within the complete ∼9 deg2 survey area.
