TL;DR
The SIMPLE survey provides deep IRAC observations over a large area, creating a comprehensive catalog that enables studies of galaxy evolution and star formation history up to redshift 1.8.
Contribution
This paper presents a detailed description of the SIMPLE survey, including observations, data reduction, and a new IRAC-selected galaxy catalog with multiwavelength photometry.
Findings
Catalog contains 43,782 sources with S/N > 5 at 3.6 um.
At z ~ 1.8, at least 30% of massive galaxies are passively evolving.
The survey enables studies of galaxy evolution up to redshift 1.8.
Abstract
We present the Spitzer IRAC/MUSYC Public Legacy Survey in the Extended CDF-South (SIMPLE), which consists of deep IRAC observations covering the ~1,600 arcmin^2 area surrounding GOODS-S. The limiting magnitudes of the SIMPLE IRAC mosaics typically are 23.8, 23.6, 21.9, and 21.7, at 3.6 um, 4.5 um, 5.8 um, and 8.0 um, respectively (5-sigma total point source magnitudes in AB). The SIMPLE IRAC images are combined with the 10'x15' GOODS IRAC mosaics in the center. We give detailed descriptions of the observations, data reduction, and properties of the final images, as well as the detection and photometry methods used to build a catalog. Using published optical and near-infrared data from the Multiwavelength Survey by Yale-Chile (MUSYC), we construct an IRAC-selected catalog, containing photometry in UBVRIz'JHK, [3.6 um], [4.5 um], [5.8 um], and [8.0 um]. The catalog contains 43,782 sources…
