斯皮策-IRAC/MIPS河外巡天（SIMES）南极场
The Spitzer-IRAC/MIPS Extragalactic survey (SIMES) in the South Ecliptic Pole field
摘要：
介绍了斯皮策-IRAC/MIPS河外巡天（SIMES）在南极（SEP）观测场的观测结果。大面积覆盖（7.7 deg $^2$），加上整个天空中最低的银河卷云辐射之一，以及斯皮策，赫歇尔，Akari和GALEX非常广泛的覆盖范围，使SIMES领域成为河外研究的理想选择。SIMES区域（$\approx$ 4：1）的细长几何形状，允许显著的宇宙方差减少，进一步提高了该领域统计研究的质量。在这里，我们提出的斯皮策/IRAC数据的还原和光度测量。勘测深度分别为1.93和1.75 $μ$ Jy（1 $σ$），深度分别为3.6和4.5 $μ$ m。我们讨论的多波长IRAC-为基础的目录，完成光学，中-和远-IR观测。我们用F $_{3.6μm} \geq 3σ$检测了341，000个源。其中，10%具有相关的24 $μ$ m对应物，而2.7%具有相关的SPIRE源。我们通过NASA/IPAC红外科学档案馆（IRSA）发布目录。本文介绍了这些IRAC数据的两个科学应用：首先，我们计算3.6 $μ$ m处的整数计数。其次，我们使用[3.6]-[4.5]颜色指数来识别z $>$ 1.3的星系团。我们在整个区域中选择了27个聚类，这一结果与以前在类似深度的研究一致。
英文摘要：
We present the Spitzer-IRAC/MIPS Extragalactic survey (SIMES) in the South Ecliptic Pole (SEP) field. The large area covered (7.7 deg$^2$), together with one of the lowest Galactic cirrus emissions in the entire sky and a very extensive coverage by Spitzer, Herschel, Akari, and GALEX, make the SIMES field ideal for extragalactic studies. The elongated geometry of the SIMES area ($\approx$4:1), allowing for a significant cosmic variance reduction, further improves the quality of statistical studies in this field. Here we present the reduction and photometric measurements of the Spitzer/IRAC data. The survey reaches a depth of 1.93 and 1.75 $μ$Jy (1$σ$) at 3.6 and 4.5 $μ$m, respectively. We discuss the multiwavelength IRAC--based catalog, completed with optical, mid-- and far--IR observations. We detect 341,000 sources with F$_{3.6μm} \geq 3σ$. Of these, 10% have an associated 24 $μ$m counterpart, while 2.7% have an associated SPIRE source. We release the catalog through the NASA/IPAC Infrared Science Archive (IRSA). Two scientific applications of these IRAC data are presented in this paper: first we compute integral number counts at 3.6 $μ$m. Second, we use the [3.6]--[4.5] color index to identify galaxy clusters at z$>$1.3. We select 27 clusters in the full area, a result consistent with previous studies at similar depth.
