Multiwavelength view of hyperluminous dust-obscured quasars at cosmic noon

Multiwavelength view of hyperluminous dust-obscured quasars at cosmic noonAbstract: The massive galaxies and their central supermassive black holes 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 may represent the critical transition phase between starburst and unobscured quasars. Using WISE All-Sky Survey data, a population of luminous dust-obscured quasars has been recently selected. We utilized the panchromatic emission of these hidden monsters at cosmic noon to explore their physical properties, such as dust, gas, stars, morphology and environment etc. Especially I will report some new results with our recent ALMA observations. Our results are generally consistent with the prediction by the merger-driven evolutionary scenario.
