"A Public Deep IRAC Survey in the Extended Chandra Deep Field South"

Principal Investigator: Pieter van Dokkum (Yale University)

Total Observatory Time: 122.9 hours

The 0.5 x 0.5 degree area surrounding the Chandra Deep Field South (CDFS) is the only cosmological survey field that has multi-wavelength coverage from X-rays to the thermal infrared and whose size exceeds the correlation length of massive galaxies at 1<z<4. More than 10,000 redshifts are known, ~800 AGN have been detected and two-band HST ACS imaging exists over the whole field. While the GALEX, Chandra, HST, and MIPS data in this field are all very deep, the existing IRAC data are not. Deep IRAC data have been shown to be pivotal in a) identifying massive high redshift objects, b) estimating galaxy masses, and c) completing the census of AGN and their host galaxies. We will obtain deep IRAC imaging across the whole Extended CDF-South to enable such analyses over a large enough area where the evolution of cosmic average properties can be well measured. The full set of Great Observatories data in this 900 square arcmin low-background field offers unparalleled archival value for future studies with ALMA and 20m-30m telescopes.
