Spitzer Wide-area InfraRed Extragalactic Survey CDFS MIPS 70 micron Catalog

The Spitzer Wide-area InfraRed Extragalactic survey (SWIRE), the largest Spitzer Legacy program, is a wide-area, imaging survey to trace the evolution of dusty, star-forming galaxies, evolved stellar populations, and AGN as a function of environment, from redshifts z~3 to the current epoch. SWIRE surveys 6 high-latitude fields, totaling ~50 sq. deg. in all 7 Spitzer bands: 3.6, 4.5, 5.8, and 8 microns with IRAC and 24, 70, and 160 microns with MIPS (Lonsdale et al. 2003). The SWIRE Legacy Extragalactic Source Catalogs will eventually contain in excess of 2 million IR-selected galaxies, from those dominated by the light of stellar populations detected primarily by IRAC, to starbursts, ultra-luminous infrared galaxies and AGN detected also by MIPS. This dataset or service is made available by the Infrared Science Archive (IRSA) at IPAC, which is operated by the California Institute of Technology under contract with the National Aeronautics and Space Administration.

斯皮策广域河外红外巡天（Spitzer Wide-area InfraRed Extragalactic Survey, SWIRE）是当前规模最大的斯皮策遗产计划项目，作为一项广域成像巡天任务，其核心目标是追踪从红移z≈3直至当前宇宙时期，不同环境下的尘埃恒星形成星系、演化恒星族群以及活动星系核（Active Galactic Nucleus, AGN）的演化规律。SWIRE覆盖6个高银纬天区，总覆盖面积约50平方度，涵盖斯皮策望远镜的全部7个观测波段：利用红外阵列相机（Infrared Array Camera, IRAC）获取3.6、4.5、5.8与8微米波段的数据，利用多波段成像光度计（Multiband Imaging Photometer for Spitzer, MIPS）获取24、70与160微米波段的数据（Lonsdale等人，2003）。SWIRE河外源遗产星表最终将收录超过200万个红外选源星系，涵盖从主要通过IRAC探测到的恒星族群主导的星系，到星暴星系、超亮红外星系以及同样可通过MIPS探测到的活动星系核等各类天体。本数据集或服务由加州理工学院受托于美国国家航空航天局运营的红外处理分析中心（Infrared Processing and Analysis Center, IPAC）下属的红外科学档案馆（Infrared Science Archive, IRSA）提供。
