We propose a nearly confusion-limited MIPS survey (24, 70, 160 microns) of the 1046+59 field to address the connection and relative importance of black-hole-driven and star-formation-driven evolution in massive galaxies. The SWIRE/Lockman deep field has the deepest-ever achieved VLA 20cm image, 2.7 microJy rms, and this winter we will add the deepest ever 90cm survey. This field is also centered on an array of 70ks Chandra pointings with deep optical/near-IR imaging and ongoing spectroscopic observations. Our goal is to use radio/X-ray/FIR diagnostics to learn the importance of AGN during the most luminous phase of galaxy formation. Because the expected 70 and 160 microns flux densities are below the Spitzer confusion limit for most individual sources, we propose to use stacking on subsets of similar sources from existing radio, X-ray images and the our proposed, deeper 24 micron survey to reach the needed sensitivity. In order to have enough sources with similar properties in absolute luminosity and redshift to use this technique we need this sensitive MIPS survey of a 0.37 degree area in our deep field with its unique ancillary data.
