Cm-wavelength Studies of Molecular Gas and Star Formation at High Redshift with the SKA

Ran Wang, Jeff Wagg, Mark T. Sargent +6

The Square Kilometre Array will be a revolutionary instrument for the study of gas in the distant Universe. At frequencies below ~50 GHz, observations of redshifted emission from l…

High-Resolution ALMA Imaging for a Gravitationally-lensed Quasar at : Constraining the AGN Contribution to Galactic-Scale Dust Heating

Minghao Yue, Xiaohui Fan, Anna-Christina Eilers +6

We present high-resolution (beam size $0\farcs076\times0\farcs040$) Atacama Large Millimeter/submillimeter Array (ALMA) observations of the far-infrared $(λ_\text{rest}=162.7μ\rm…

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…

The SUPERCOLD-CGM survey: II. [\ion{C}{1}] emission and the physical conditions of cold gas in Enormous Ly nebulae at

Jianan Li, Bjorn H. C. Emonts, Zheng Cai +13

We report ALMA and ACA observations of atomic carbon ([\ion{C}{1}]) and dust continuum in 10 Enormous Ly Nebulae hosting ultra-luminous Type-I QSOs at , as pa…

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…

A Spatially Resolved [CII] Survey of 31 Massive Galaxies Hosting Luminous Quasars

Feige Wang, Jinyi Yang, Xiaohui Fan +15

The [CII] 158 m emission line and the underlying far-infrared (FIR) dust continuum are important tracers for studying star formation and kinematic properties of early galaxies.…
