Evidence of Gas Depletion in Quasars with Moderate Radio Emission
Yuhan Wen, Ran Wang, Luis C. Ho +4
The energy released by active galactic nuclei (AGNs) is considered to have a profound impact on the cold gas properties of their host galaxies, potentially heating or removing the…

Overmassive Black holes live in compact galaxies in the early Universe
Yuxuan Wu, Tao Wang, Daizhong Liu +9
A significant population of quasars have been found to exist within the first Gyr of cosmic time. Most of them have high black hole (BH) masses ($M_{\rm BH} \sim 10^{8-10} M_{\odot…

Assessing the dark matter content of two quasar host galaxies at z~6 through gas kinematics
Qinyue Fei, John D. Silverman, Seiji Fujimoto +11
We conduct a study of the gas kinematics of two quasar host galaxies at traced by the [CII] emission line using ALMA. By combining deep observations at both low and hig…
