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…
Homogeneous measurements of proximity zone sizes for 59 quasars in the Epoch of Reionization
Silvia Onorato, Joseph F. Hennawi, Elia Pizzati +2
The overionized regions surrounding high-redshift quasars, known as proximity zones, provide a window into the interaction between supermassive black holes (SMBHs) and the intergal…
Infrared emission from quasar host galaxies: a direct estimate of dust physical properties
M. Costa, R. Decarli, F. Pozzi +6
Quasars at the dawn of Cosmic Time () are fundamental probes to investigate the early co-evolution of supermassive black holes and their host galaxy. Nevertheless, their infra…
Discovery and characterization of 25 new quasars at 4.6 < z < 6.9 from wide-field multi-band surveys
Silvia Belladitta, Eduardo Bañados, Zhang-Liang Xie +18
Luminous quasars at provide key insights into the early Universe. Their rarity necessitates wide-field multi-band surveys to efficiently separate them from the main astrophys…
