Abstract:
Spitzer is creating a vast legacy of 24 micron imaging, with hundreds of
thousands of sources detected at cosmological distances. In principle, 24 micron
data are the most sensitive probe of dust−enshrouded star formation and distant
active galactic nuclei. In practice, at z > 1, they sample mid−infrared
wavelengths complex in structure (PAH emission and silicate absorption) and
physics (PAH excitation, metallicity dependence, extinction, warm dust and
hidden AGN). Other data are needed to understand MIR emission, to calibrate its
relation to star formation, to establish its dependence on other galaxy
properties, to measure how many atypical objects there are, and to learn how to
account for them in conclusions drawn from deep surveys. We propose a program of
very deep MIPS imaging geared toward 70 micron detection of 1000 "normal"
IR−luminous galaxies at 0.5 < z < 2.5 at wavelengths which trace thermal dust
emission which more directly correlates with physical properties of interest
such as star formation rates. We will survey 2200 square arcmin in three premier
deep survey fields using far−infrared, radio and submillimeter data to measure
bolometric luminosities, dust temperatures and masses, to quantify the
