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.

Co-rotating cool CGM clouds in 21 galaxies are ~0.5 dex more metal-poor within 30 degrees of the major axis than at larger azimuthal angles.
A 4.5σ excess RM dispersion of 4.13 ± 0.91 rad m^{-2} is found in 191 Mg II sightlines versus controls, implying model-dependent CGM magnetic fields of 0.4-0.8 μG at projected radii 20-150 kpc and z~1.14.
A new public library generates millions of mock quasar absorption spectra from cosmological simulations, using a novel mesh-free Voronoi ray-tracing algorithm.
Mock X-ray observations of 28 simulated Milky Way-mass galaxies show that galactic feedback prescriptions produce distinguishable hot-CGM surface brightness, kinematic, and temperature signatures, including universal r^-3 profiles in non-cosmic-ray runs.
At z~1, 67% of MgII absorbers are associated with multiple galaxies, and groups show five times stronger MgII absorption and three times higher covering fraction than isolated galaxies.
MgII gas covering fraction and absorption strength around low-redshift galaxies decline steeply with projected distance and are higher for star-forming than for quiescent galaxies.
