Abstract

We propose to obtain followup IRAC imaging data for four key targets from the 14 sq. deg. Science Demonstration Phase field of the Herschel-ATLAS survey. This will provide a vital component in validating and confirming the discoveries we have made with Herschel observations. H-ATLAS is the largest Open-Time Key Program of Herschel both in terms of time awarded (600 hours) and the total survey area (550 sq. degrees). The targets of this proposed DDT program are (a) a proto-cluster of sub-mm galaxies at a redshift between 2 and 2.5 selected based on sub-mm colors; (b) 2 gravitationally lensed sources at redshift of 3.04 and 2.06; and (c) an optically dark compact core, possibly a Bok globule with a unique origin given the location in the Galactic plane. Spitzer IRAC data will allow us to find counterparts to sub-mm sources in the high redshift proto-galaxy cluster and improve photometric redshift estimates of member galaxies. IRAC data of lensed sources will establish the spectral energy distribution of high-redshift sources and guide us for future followup of the 100 lensed sources expected in all of H-ATLAS 550 sq. degrees. IRAC data of the Galactic will allow us to look for the embedded Class 0 object in the sub-mm compact core.
