Fast Outflow in the Host Galaxy of the Luminous z 7.5 Quasar J10072115

Weizhe Liu, Xiaohui Fan, Jinyi Yang +24

James Webb Space Telescope opens a new window to directly probe luminous quasars powered by billion solar mass black holes in the epoch of reionization and their co-evolution with…

No Redshift Evolution in the Fe II/Mg II Flux Ratios of Quasars across Cosmic Time

Danyang Jiang, Masafusa Onoue, Linhua Jiang +13

The Fe II/Mg II emission line flux ratio in quasar spectra serves as a proxy for the relative Fe to alpha-element abundances in the broad line regions of quasars. Due to the expect…

The Decoupled Kinematics of high-z QSO Host Galaxies and their Lya halos

Alyssa Drake, Marcel Neeleman, Bram P. Venemans +7

We present a comparison of the interstellar medium traced by [CII] (ALMA), and ionised halo gas traced by Lya (MUSE), in and around QSO host galaxies at z~6. To date, 18 QSOs at th…

Staring at the Shadows of Archaic Galaxies: Damped Ly and Metal Absorbers toward a Young Weak-line Quasar

Irham Taufik Andika, Knud Jahnke, Eduardo Bañados +6

We characterize the Ly halo and absorption systems toward PSO J083+11, a unique weak-line quasar, using Gemini/GNIRS, Magellan/FIRE, and VLT/MUSE data. Strong absorpt…

Chemical Abundance of z~6 Quasar Broad-Line Regions in the XQR-30 Sample

Samuel Lai, Fuyan Bian, Christopher A. Onken +17

The elemental abundances in the broad-line regions of high-redshift quasars trace the chemical evolution in the nuclear regions of massive galaxies in the early universe. In this w…

APEX at the QSO MUSEUM: molecular gas reservoirs associated with 3 quasars and their link to the extended Ly emission

N. Muñoz-Elgueta, F. Arrigoni Battaia, G. Kauffmann +5

Cool gas (T10~K) traced by hydrogen Ly emission is now routinely detected around quasars, but little is known about their molecular gas reservoirs. Here, we…
