We propose to obtain IRAC1,2 observations (~1400 sec) of a flux-limited sample of 88 luminous infrared galaxies (LIRGs) originally selected from the IRAS Revised Bright Galaxy Survey, in order to measure the full extent and internal structure of the large tidal debris fields that have recently been revealed (~70-130 kpc diameter) in deep optical imaging of these objects using the Subaru 8m Telescope on Mauna Kea. Our 88 targets are part of the Great Observatories All-Sky LIRGs Survey (GOALS), for which we are obtaining both spacecraft and ground-based data at a wide range of wavelengths (radio thru X-Rays). All of our targets have previous shallow (~150 sec) IRAC observations, which are insufficient for detecting all but the brightest, and much less extended tidal features. Our deeper IRAC observations will allow us to better characterize the history, geometry and morphology of the interaction for comparison with new sets of model calculations using 'IDENTIKIT' (Barnes & Hibbard, 2009). We also plan to combine our new IRAC1,2 data with deep optical (Subaru and VLT) and NIR (HST-NIC, -WFC3) data to determine spectral energy distributions, and to measure stellar masses as well as detect warm dust in these extended features. These new data will also allow us for the first time to obtain a clearer picture of the possible interrelatedness of nearby objects (e.g. putative tidal dwarf galaxies, and other previously disconnected arms, shells, etc.) to the merger history of this complete sample of local (U)LIRGs.
