To Deeply Investigate Distant Quasars Using JWST and ALMA


I am leading several JWST and ALMA programs to study a sample of reionization-era luminous quasars with multi-wavelength imaging and spectropscopic observations. Our targets include a well selected z ~ 6.5 - 6.8 quasar sample, a massive z = 6.6 proto-culster anchored by luminous quasar, a dust reddened z = 7.1 quasar, and the three most distant known quasars at z > 7.5 (link). The transformational ability of JWST will allow observations of these quasars with wide wavelength coverage, high spatial resolution, and high sensitivity. Together with ALMA, the in-depth observations covering 30 quasars at z ~ 6.5 - 7.6 will allow a panchromatic view of the quasar central engine and host galaxy assembly. I also participate in other three JWST programs focusing on high-redshift quasar-companion system, reionization history, and faint reionization-era quasars. These upcoming data will revolutionize our understanding of these earliest supermassive black holes and their host galaixes. JWST observations have started in August 2022. I will present our early results soon.
