CO(7-6) and [C I](2-1) survey in z > 6 quasars
Fuxiang Xu, Roberto Decarli, Ran Wang +13
High-redshift () quasars trace the earliest supermassive black holes and intense star formation, offering key laboratories for black hole-galaxy evolution at cosmic dawn…

Constraining the excitation of molecular gas in Two Quasar-Starburst Systems at
Fuxiang Xu, Ran Wang, Jianan Li +15
We present NOrthern Extended Millimeter Array observations of CO(8-7), (9-8), and (10-9) lines, as well as the underlying continuum for two far-infrared luminous quasars: SDSS J205…
