Colloquium by Ran Wang (PKU)

Millimeter and radio studies of quasars and their host galaxies in the most distant universe

Abstract: The large millimeter and radio telescopes, such as ALMA and the JVLA, provide us the best opportunity to study the formation of the first supermassive black holes (SMBHs) and galaxies at the earliest epoch. In particular, huge amount of dust and molecular gas were detected in about 30% of the luminous quasars at z~6, which suggests an early phase of SMBH-galaxy evolution with massive star formation. The star formation rates estimated with the FIR dust continuum emission are about a few hundred to a thousand Msun/yr. In this talk, I will present our recent millimeter and radio observations of the quasar samples at z~6 and discuss how the results constrain the quasar-galaxy coevolution in the early universe.
