Abstract

With IRAC at 3.6 micron and MIPS at 24 micron we like to image the largest region yet mapped deeply at mm or submm wavelengths, the Abell 2125 MAMBO Deep Field. Our aim is to identify at arcsec resolution the population of dusty mm galaxies that are particularly difficult to identify at any other waveband, presumably because they lie at redshifts well above 3. These Spitzer Space Telescope observations in combination with our millimeter, optical and radio photometry will resolve the distance--dust temperature degeneracy, thus providing good photometric redshifts which will allow us, for the first time, to obtain a solid measure of the number density of very massive starburst galaxies at redshifts above 3, and thereby to place the most stringent constraints on galaxy formation models. Spitzer observations will furthermore help identify the true counterparts of the mm galaxies undetected at radio wavelengths, allow realistic estimates of the infrared luminosities and dust masses, and permit a look at the environments of these early, massive starbursts. The highest redshift sources identified thereby (possibly producing the highest redshift object ever detected) will motivate follow-up optical, near-IR and mm spectroscopy to obtain accurate redshifts and to search for molecular (CO, HCN) and atomic (CI) emission, opening up detailed studies of the most distant dusty starburst galaxies, likely corresponding to forming massive spheroidal galaxies.
