我们给出了从欧洲大面积国际标准化组织调查(ELAIS)的初步分析中提取的90μm处的结果和源计数。这项调查覆盖了四个主要区域约12摄氏度的天空，是使用红外空间天文台(ISO)上的ISOPHOT仪器进行的。这项调查至少比IRAS100-μm调查深一个数量级，预计将为星系的形成和演化提供约束。在光学图像上，大多数探测到的源都与星系有关。在某些情况下，光学关联是相互作用的星系对或小星系群，这表明样本可能包括相当一部分发光的红外星系。从探测到的源的可靠子集中提取的源计数与恒星暴增星系群的强演化模型一致。
We present results and source counts at 90 μm extracted from the preliminary analysis of the European Large Area ISO Survey (ELAIS). The survey covered about 12 deg 2 of the sky in four main areas and was carried out with the ISOPHOT instrument onboard the Infrared Space Observatory (ISO) . The survey is at least an order of magnitude deeper than the IRAS 100-μm survey and is expected to provide constraints on the formation and evolution of galaxies. The majority of the detected sources are associated with galaxies on optical images. In some cases the optical associations are interacting pairs or small groups of galaxies, suggesting that the sample may include a significant fraction of luminous infrared galaxies. The source counts extracted from a reliable subset of the detected sources are in agreement with strongly evolving models of the starburst galaxy population.
