Idealized simulations with live gas particles show the LMC corona's present-day velocity and column density profiles match a first-passage orbit but are too low in a second-passage orbit, yielding truncation radii of 16.6 kpc versus 5.7 kpc and strongly disfavoring the latter.
Ancient cosmic ray halos from the central galaxy boost Perseus's cool core via inverse-Compton scattering, simultaneously explaining radio minihalo, giant halo, X-ray properties, and gamma-ray data without re-acceleration.
Mutual information analysis of TNG50 simulations shows gravitational potential and total energy retain merger mass and infall time information longest, while radial velocity loses it within ~5 Gyr, with washout depending on radius, merger age, and mass.
FIRE-2 simulations with gravitational torque-driven and free-fall accretion models predict enough high-redshift AGN to explain little red dots, with a super-Eddington Eddington-limited scenario for M_BH >= 2e5 Msun in M_star >= 2e7 Msun galaxies reproducing key observations.
Milky Way-mass dark matter density profiles in IllustrisTNG are largely insensitive to astrophysics and cosmology variations, dominated by halo-to-halo variance instead.
Varied cosmic ray feedback models from AGN in FIRE-3 simulations all quench massive galaxies consistently with observations but produce vastly different circumgalactic medium properties.
