我们直接测量了产生宇宙红外背景（CIB）的星系的平均物理性质（远红外光度、温度和质量）的红移演化，使用了气球载大孔径亚毫米望远镜（BLAST）和斯皮策（Spitzer）的测量结果，这些测量结果限制了宇宙红外背景（CIB）的发射峰值。已知该样本在BLAST波段产生与完整CIB一致的表面亮度，并且所有物体的光度红移都被识别出来。我们发现70 μm的背景大部分在z≤1处产生，500 μm的背景大部分在z≤1处产生。在平均光度从~ 109-1012 L☉有显著的增长，在平均温度从红移0 < z < 3增加了10 K。然而，在相同红移范围内，这些星系中移动的尘埃团只有微弱的正演化。我们还测量了远红外亮度密度的演化，以及这些天体的恒星形成率历史，发现与其他红外研究的z ~ 1很好地一致，超过了光学选择星系的贡献。
We directly measure redshift evolution in the mean physical properties (far-infrared luminosity, temperature, and mass) of the galaxies that produce the cosmic infrared background (CIB), using measurements from the Balloon-borne Large Aperture Submillimeter Telescope (BLAST), and Spitzer which constrain the CIB emission peak. This sample is known to produce a surface brightness in the BLAST bands consistent with the full CIB, and photometric redshifts are identified for all of the objects. We find that most of the 70 μm background is generated at z ≲ 1 and the 500 μm background generated at z ≳ 1. A significant growth is observed in the mean luminosity from ∼109–1012 L☉, and in the mean temperature by 10 K, from redshifts 0 < z < 3. However, there is only weak positive evolution in the comoving dust mass in these galaxies across the same redshift range. We also measure the evolution of the far-infrared luminosity density, and the star formation rate history for these objects, finding good agreement with other infrared studies up to z ∼ 1, exceeding the contribution attributed to optically selected galaxies.
