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…
Under the glare of a luminous quasar, the FIR continuum is still an excellent tracer of the ISM down to the central kiloparsec
John D. Silverman, Emanuele Daddi, Qing-Hua Tan +7
Contamination-free assessments of the interstellar medium and star formation in quasar host galaxies, particularly based on the far-infrared, offer insights into the role of superm…
The MALATANG survey: Dense gas distribution on sub-kiloparsec scales across the disk of M82
Jian-Fa Wang, Yu Gao, Qing-Hua Tan +23
We present observations of HCN J=4-3 and HCO^+ J=4-3 lines obtained with the James Clerk Maxwell Telescope as part of the MALATANG survey, combined with archival HCN J=1-0 and HCO^…
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…
