An extended Lyα halo is detected around the z=6.64 BAL quasar J0910-0414, extending to 11 pkpc with rotation-like kinematics, lower velocity dispersion than the host core, and contributing 55% of the total Lyα flux due to central absorption.

ALMA survey of CO(7-6) and [C I](2-1) in 18 z~6 quasars yields molecular gas mass estimates from multiple tracers and indicates that PDR models cannot fully account for the observed excitation, pointing to additional heating processes.
Lya nebulae around unobscured quasars are more extended, asymmetric, and show steeper velocity dispersion declines than those around obscured quasars, supporting an evolutionary AGN model at cosmic noon.
