FIRE-2 simulations show per-galaxy tidal disruption rates peak near z=2.5 at 4e-4 per year, correlate with SFR and central density, and remain high in satellite galaxies at early times.
A toy model of dust rings in TDEs predicts brighter IR emission on-axis, explaining X-ray/IR correlations and enabling viewing-angle constraints from observed light curves.
Non-detections of expected third flares in TDE 2022dbl and TDE 2020vdq support rpTDE interpretation over independent events, with modeling favoring bound main-sequence star orbits and deep initial encounters.
Mid-IR search of NEOWISE yields 10 TDEs above 3e43 erg/s with volumetric rate 1.2e-10 Mpc^-3 yr^-1, showing suppression at high luminosity explained by reduced TDE rate for larger black holes.
Precessing TDE disks imprint double-to-single peak transitions and periodic ripples on infrared dust echoes, which the authors fit to AT 2022agi and AT 2020nov.
An obscured tidal disruption event in SDSS J010320.39+140152.5 was identified through its mid- and near-infrared dust echo peaking at 5.4e43 Lsun.

Enhancement of the Rate of Tidal Disruption Events in Active Galactic Nuclei due to the Sweeping Secular Resonance Mechanism
