摘要:

我们已经进行了两次极深的调查与SPIRE,赫歇尔上的两个相机之一,在250微米,接近远红外背景的峰值。我们已经使用的结果,以调查的演变的休息帧250微米光度函数的z=2。我们发现的证据表明,强进化的红移约为1,但在最弱的进化超过这个红移的证据。我们的研究结果表明,今天宇宙中的大部分恒星和金属都是在z<1.4的螺旋星系中形成的。

英文摘要:

We have carried out two extremely deep surveys with SPIRE, one of the two cameras on Herschel, at 250 microns, close to the peak of the far-infrared background. We have used the results to investigate the evolution of the rest-frame 250-micron luminosity function out to z=2. We find evidence for strong evolution out to a redshift of around 1 but evidence for at most weak evolution beyond this redshift. Our results suggest that a significant part of the stars and metals in the Universe today were formed at z<1.4 in spiral galaxies.
