Title: The Infrared Zoo at z~2: Connecting High Redshift Galaxy Populations Abstract: Redshift z ~ 2 is perhaps the richest epoch for understanding galaxy assembly. During this era, the bulk of the Universal stellar mass was assembled, and the cosmic SFR density and black hole growth both peak. While it is clear that infrared-selected galaxies at z~2 appear to be a key player in both forming copious numbers of stars, and growing black holes, the myriad of selection techniques ranging from 24 micron to 1 mm has uncovered a veritable zoo of galaxies (e.g. Dust Obscured Galaxies [DOGs] and Submillimeter Galaxies [SMGs]) whose relationship to one another is unclear. Utilizing a novel combination of high resolution hydrodynamic simulations of galaxy evolution, 3D polychromatic dust radiative transfer calculations and 3D non-LTE molecular line radiative transfer simulations, we will synthesize the plethora of species in this zoo of galaxies, and provide a merger-driven unifying model connecting DOGs and SMGs. We will discuss the dominant power source (ie star-formation or AGN activity) as galaxies evolve through their various phases, and assess their relative overlaps. We will show how these galaxies relate to the BzK populations. Finally, we will make testable predictions for these models for the SMA, Herschel and JWST.
