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 starbursts and unobscured quasars. Using WISE All-Sky Survey data, a population of luminous dust-obscured quasars has been recently selected. We utilized the panchromatic emissions of these hidden monsters to explore their physical properties, such as dust, gas, stars, morphology and environment etc. Especially, we will report the results of our recent ALMA observations which provide a unique chance to study the dust and gas properties in the host galaxies of these obscured quasars. Our results are consistent with the prediction by the merger-driven evolutionary scenario.
Prof. Lulu Fan is from University of Science and Technology of China (USTC). Prof. Fan received his bachelor degree from USTC in 2004 and his doctoral degree from International School for Advanced Studies, Italy (SISSA) in October 2011. He then worked as a postdoctoral scholar at USTC and Chalmers University of Technology in Sweden before joining Shandong University in 2015. Since 2019, he went back to USTC. He was supported by the Natural Science Fund for Distinguished Young Scholars of Shandong Province and the National Science Foundation for Excellent Young Scholars of China in 2018. His main research interests are galaxy structure and co-evolution of galaxies and their central supermassive black holes.
