The Pedigrees of DOGs (Dust-Obscured Galaxies)
arXiv:0905.4531
Abstract
A simple mid-infrared-to-optical color criterion of R-[24]>14 Vega mag results in a robust selection of approximately half of the redshift 2 ultraluminous infrared galaxy (ULIRG) population. These `Dust-Obscured Galaxies', or DOGs, have many properties that suggest that they are good candidates for systems in a transition phase between gas-rich mergers and QSOs.
