论文摘要

Vera C. rubin天文台对时空的遗产调查（LSST）将观察到几个深度钻井场（DDFS）的深度，并且比主要调查更快。在本文中，我们描述了``deepdrill''调查，该调查使用Spitzer Space望远镜红外阵列摄像头（IRAC）观察两个频段中当前定义的DDF中的三个，以3.6 $ $ M和4.5 $ $ $ m m为中心。这些观察结果扩大了该区域，该区域由Spitzer外层次代表体积调查（SERVS）在这三个领域的早期观察结果所覆盖。组合的深钻和SERV数据涵盖了扩展的Chandra Deep-South-South Field Field（ECDFS），Elais-S1场（ES1）和XMM大型结构调查场（XMM-LSS）中LSST DDF的足迹。该观察结果达到了大约$5σ$ point-source的深度2 $ $ $ jy（对应于23.1的量级；足以检测到两个乐队的10 $^{11} m _ {\ odot} $ galaxy of two $ \ $ \ $ \ $ \ deg^2 $^2 $^2 $^$^2 $^2 $^2 $^2 $^2 $^2 $^2 $^2 $^2 $^2 $^2 $。双波段目录总共包含235万个来源。在本文中，我们描述了调查中的观察结果和数据产品，以及在调查中的星系属性的概述。我们将源计数与来自星系形成的鲨鱼半分析模型的预测进行了比较。我们还确定了具有极红色（[3.6] $ - $ [4.5] $> 1.2 $）颜色的一系列来源，我们表明的主要由高度观察的活性银河核组成。

The Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST) will observe several Deep Drilling Fields (DDFs) to a greater depth and with a more rapid cadence than the main survey. In this paper, we describe the ``DeepDrill'' survey, which used the Spitzer Space Telescope Infrared Array Camera (IRAC) to observe three of the four currently defined DDFs in two bands, centered on 3.6 $μ$m and 4.5 $μ$m. These observations expand the area which was covered by an earlier set of observations in these three fields by the Spitzer Extragalactic Representative Volume Survey (SERVS). The combined DeepDrill and SERVS data cover the footprints of the LSST DDFs in the Extended Chandra Deep Field-South field (ECDFS), the ELAIS-S1 field (ES1), and the XMM Large-Scale Structure Survey field (XMM-LSS). The observations reach an approximate $5σ$ point-source depth of 2 $μ$Jy (corresponding to an AB magnitude of 23.1; sufficient to detect a 10$^{11} M_{\odot}$ galaxy out to $z\approx 5$) in each of the two bands over a total area of $\approx 29\,$deg$^2$. The dual-band catalogues contain a total of 2.35 million sources. In this paper we describe the observations and data products from the survey, and an overview of the properties of galaxies in the survey. We compare the source counts to predictions from the SHARK semi-analytic model of galaxy formation. We also identify a population of sources with extremely red ([3.6]$-$[4.5] $>1.2$) colours which we show mostly consists of highly-obscured active galactic nuclei.
