Active star formation and huge amount of molecular gas were detected in the host galaxies of quasars from local to high-z universe, implying co-evolution between the supermassive black holes (SMBHs) and their host galaxies.
The cold interstellar medium (ISM) in the quasar host galaxies fuels both rapid SMBH accretion and massive star formation. It provides an ideal tracer to probe the early growth of the quasar-galaxy systems. The powerful interferometer telescope arrays at submillimeter/millimeter wavelengths (e.g., ALMA, NOEMA) open unique opportunities to detect and image the cold ISM from the earliest quasar host galaxies on sub-kpc scale. In this talk,
I would like to review our recent studies of the physical and dynamical properties of the cold ISM from the young quasar host galaxies discovered at the highest redshift and discuss our understanding of SMBH-galaxy co-evolution in the early universe.
I am working on millimeter and radio studies of the co-evolution between supermassive black holes and their host galaxies in the early universe. I have developed a series of observational programs to search and map the dust and gas components in the host galaxies of quasars discovered at z∼6, using the large millimeter and centimeter telescopes, such as ALMA, VLA, JCMT, and NOEMA. I am also interested in observational studies of dusty starburst galaxies in massive large-scale structures associated with quasars and Lyman alpha nebula.
