Low-Redshift Hot DOGs

Hot dust-obscured galaxies (Hot DOGs) are a rare population of dusty, hyper-luminous galaxies discovered at high redshift (z~2-3). The follow-up studies reveal that their extremely high luminosities likely come from the accretion onto supermassive black holes (SMBHs) at the Eddington limit, making them among the most luminous galaxies in the universe. And their host galaxies are gas-rich and have intense star-formation activity, although these systems host powerful AGN. We recently discovered and confirmed a low-redshift Hot DOG and then established a sample of low-redshift Hot DOGs by a systematic search. I will introduce the general properties of this population and present the detailed properties of the first discovered low-redshift Hot DOG W1904+4853.
