The Nature of Faint 24 micron Sources Seen in Spitzer Observations of ELAIS-N1

Abstract

The Spitzer Space Telescope has undertaken the deepest ever observations of the 24 micron sky in the ELAIS-N1 field as part of GOODS Science Verification observations. We present the shape of the 24 micron source counts in the flux range 20-1000 microJy, discuss the redshift distribution and nature of these sources with particular emphasis on their near-infrared counterparts.
