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 simulation analysis finds early-forming halos show higher stellar mass, metallicity, lower CGM gas mass and sSFR at z=0, with mass-dependent CGM metallicity reversal and cold-gas kinematics differences.
Multiphase CGM absorption in DESI data shows cooler ions (Ca II, Mg II) have steeper radial W profiles than C IV, with galaxy vs. quasar differences, consistent with simulations.
