摘要:

研究星系演化和宇宙红外背景的性质的深远红外测光调查是赫歇尔飞行任务的一个关键优势。我们描述了PACS进化探测器(PEP)保证时间密钥计划的科学动机及其在补充Herschel调查中的作用,以及包括流行的多波长场(如GOODS,COSMOS,Lockman Hole,ECDFS,EGS)的场选择。我们提供了一个帐户的观测策略和数据处理方法。第一个科学结果的概述说明了PEP在为高红移星系群提供热量恒星形成率方面的潜力,从而测试和超级播种以前从其他波长推断的结果,并使广泛的星系演化研究成为可能。

英文摘要:

Deep far-infrared photometric surveys studying galaxy evolution and the nature of the cosmic infrared background are a key strength of the Herschel mission. We describe the scientific motivation for the PACS Evolutionary Probe (PEP) guaranteed time key program and its role in the complement of Herschel surveys, and the field selection which includes popular multiwavelength fields such as GOODS, COSMOS, Lockman Hole, ECDFS, EGS. We provide an account of the observing strategies and data reduction methods used. An overview of first science results illustrates the potential of PEP in providing calorimetric star formation rates for high redshift galaxy populations, thus testing and superseeding previous extrapolations from other wavelengths, and enabling a wide range of galaxy evolution studies.
