Hot dust-obscured galaxies: Catching the maximum accretion phase of super massive black holes

 Hot, Dust-Obscured Galaxies, or ”Hot DOGs” are a rare, dusty, hyperluminous galaxy population recently discovered by the WISE mission. Peaking at redshifts 2-3, and with typical luminosities of 10^13−10^14 Lsun, they are the most luminous obscured galaxies in the universe. Our recent studies reveal that super massive black holes in this Hot DOGs may be accreting at the highest possible rate, similar to those in z~6 quasars. Hot DOGs likely trace a high-luminosity, high-accreting, and high-obscuration, transitional phase between obscured and unobscured quasars. I will discuss the possible relations between Hot DOGs and other known high-z populations hosting super massive black holes.
