The WISE mission has recently discovered a rare population of high redshift, hyper-luminous infrared galaxies, all with bolometric luminosities exceeding 10^13 L_Sun, and many beyond 10^14 L_Sun. Characterized by their extremely red mid-IR colors and very hot dust temperatures, these hot, dust-obscured galaxies (Hot DOGs) likely probe a key stage in the galaxy evolution paradigm. We propose here to use FLAMINGOS-2 to observe a sample of these objects. FLAMINGOS-2 observations may allow us to estimate their central super-massive black hole masses, as well as learn about the dust distribution from ionization line diagnostics.
