Scientific paper

We construct deep infrared source counts in the deepest infrared image ever taken using the IRAC instrument aboard the Spitzer Space Telescope. We also use the integrated flux from these sources to estimate the contribution from extragalactic sources to the Cosmic Infrared Background (CIRB). Finally, we use the deep infrared photometry mosaic along with observations in the z´ band taken with the MMT and F814W band image taken with HST to identify candidate Lyman-Break Galaxies. We find 30 candidate galaxies at redshifts 6 and 7 within the compared field size of 220 arcminutes2. This work is supported in part by the NSF REU and DOD ASSURE programs under NSF grant no. 0754568 and by the Smithsonian Institution.
