Abstract:The massive galaxies and their central supermassive black holes (SMBHs) co-evolution scenario proposes that a gas-rich major merger can trigger the central starburst and feeding the SMBH accretion, and then star formation has eventually been quenched by quasar feedback. In this evolutionary sequence, dust-obscured quasars could represent the critical transition phase and are perfect candidates for studying the interplay between SMBHs and their hosts. In this talk, I will introduce our multiwavelength studies of a recently discovered population of hyperluminous, heavily dust-obscured quasars in WISE all-sky survey (so-called Hot DOGs). Taking advantage of multiwavelength data including HST, Keck, WISE, Herschel, JCMT and ALMA etc, we can not only derive the physical properties of their hosts and SMBHs, but also provide the observational evidence for/against the galaxy evolution models.
