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.

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.
TNG50 shows galactic outflow mass loading is non-monotonic with stellar mass, rising rapidly above 10^10.5 Msun due to black hole feedback, and produces fast multi-phase outflows with emergent collimation.
UV background suppresses NEI in galaxy haloes, restoring equilibrium shock thresholds and producing extended absorption columns for OVI, CIV, and HI beyond the virial radius.

First Results from the TNG50 Simulation: Galactic outflows driven by supernovae and black hole feedback
TNG50 shows galactic outflow mass loading is non-monotonic with stellar mass, rising rapidly above 10^10.5 Msun due to black hole feedback, and produces fast multi-phase outflows with emergent collimation.
