In the IllustrisTNG model, CGM gas around z=1 galaxies mixes quickly and separates into cold inner and warm-hot outer phases within 500 Myr due to feedback, with kinematic decorrelation over 400 Myr and ion-specific phases lasting different durations.

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.
Cooler CGM phases traced by Ca II and Mg II exhibit steeper radial equivalent width profiles than the warmer C IV phase, with host-type differences and stellar-mass dependence.
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.
The paper advocates for boosting HST's orbit to enable unique UV emission-line imaging of the circumgalactic medium, delivering the first statistical constraints on warm-hot gas and aiding target selection for the future Habitable Worlds Observatory.
