我们给出了南极望远镜最近发现的11个典型例子的APEX SABOCA350 μm和LABOCA870 μm观测结果，这些星系是罕见的、极其明亮的(S1.4 mm>；15 mJy)，以尘埃为主的毫米级星系。所有11个源都被LABOCA以40 μm<；S870 m<；130 MJy的强健探测到，大约比标准的亚毫米星系(SMG)高出一个数量级。SABOCA在>；3σ也探测到了其中六个源，探测或上限对其峰值附近的光谱能量分布的形状提供了关键限制。我们用一个简单的修正黑体模拟了这些星系的SED，并对文献中已知红移的SMG样本进行了同样的分析。这些校准样本为类似SMG种群的尘埃温度分布提供信息，而先前的尘埃温度允许我们推导出光源的光度红移估计和远红外光度。我们发现红移的中位数比正常SMG人群的推论要高。我们还根据温度和视光度得出了源的视大小，发现它们看起来比我们未透镜的校准样本更大，这支持了这些源被视线上的质量结构引力放大的想法。
We present APEX SABOCA 350 μm and LABOCA 870 μm observations of 11 representative examples of the rare, extremely bright (S1.4 mm > 15 mJy), dust-dominated millimeter-selected galaxies recently discovered by the South Pole Telescope. All 11 sources are robustly detected with LABOCA with 40 mJy < S870 μm < 130 mJy, approximately an order of magnitude higher than the canonical submillimeter galaxy (SMG) population. Six of the sources are also detected by SABOCA at >3σ, with the detections or upper limits providing a key constraint on the shape of the spectral energy distribution (SED) near its peak. We model the SEDs of these galaxies using a simple modified blackbody and perform the same analysis on samples of SMGs of known redshift from the literature. These calibration samples inform the distribution of dust temperature for similar SMG populations, and this dust temperature prior allows us to derive photometric redshift estimates and far-infrared luminosities for the sources. We find a median redshift of , higher than the inferred for the normal SMG population. We also derive the apparent size of the sources from the temperature and apparent luminosity, finding them to appear larger than our unlensed calibration sample, which supports the idea that these sources are gravitationally magnified by massive structures along the line of sight.
