TLDR
The Extended Groth Strip (EGS) is one of the premier fields for extragalactic deep surveys as discussed by the authors, and the catalog comprises 57,434 objects detected at 3.6 μm with 84, 28, and 24% also detected at 4.5, 5.8, and 8.0 μm, respectively.Abstract:
The Extended Groth Strip (EGS) is one of the premier fields for extragalactic deep surveys. Deep observations of the EGS with the Infrared Array Camera (IRAC) on the Spitzer Space Telescope cover an area of 0.38 deg2 to a 50% completeness limit of 1.5 μJy at 3.6 μm. The catalog comprises 57,434 objects detected at 3.6 μm, with 84%, 28%, and 24% also detected at 4.5, 5.8, and 8.0 μm, respectively. Number counts are consistent with results from other Spitzer surveys. Color distributions show that the EGS IRAC sources comprise a mixture of populations: low-redshift star-forming galaxies, quiescent galaxies dominated by stellar emission at a range of redshifts, and high-redshift galaxies and AGNs.read more

TL;DR: In this paper, a photometric analysis of the CANDELS and 3D-HST HST imaging and the ancillary imaging data at wavelengths 0.3-8 μm is presented, where objects were selected in the WFC3 near-IR bands and their spectral energy distributions were determined by carefully taking the effects of the point-spread function in each observation into account.

TL;DR: In this article, the authors study the buildup of the bimodal galaxy population using the NEWFIRM Medium-Band Survey, which provides excellent redshifts and well-sampled spectral energy distributions of {approx}27, 000 galaxies with K 3 x 10{sup 10} M{sub sun} increases by a factor of {approximately}10 from z − 2 to the present day, whereas the mass density in star-forming galaxies is flat or decreases over the same time period.
