Spatially resolved spectroscopy shows SDSS1335+0728 has a three-zone ionisation structure, optically thin dust, and sustained low-level nuclear activity for at least 1500 years, implying the Ansky event is a faint transient in an already accreting low-mass SMBH.

The mHz QPO in 1ES 1927+654 has persisted and stabilized at ~2.5 mHz with stable soft lags, no strong harmonic, and repeatable large-amplitude flux patterns, also seen in NuSTAR.
Cold compact circumbinary rings evolve into highly eccentric disks with suppressed accretion and dominant variability at ~0.1 times the binary orbital frequency via a stream impact mechanism.
WD–IMBH tidal disruption disks are advection-dominated, radiate near-Eddington soft X-rays, can emit Galactic MeV neutrinos, and produce decihertz GW bursts.
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.
A time-dependent model shows that star-disk collisions in TDE systems hosting EMRIs can eject 10^{-3} to 1 solar masses at 0.02-0.1c years after the initial flare, producing radio emission via interaction with circumnuclear material.
A criterion of |Δg| > 0.4 mag and |Δ(g-r)| > 0.2 mag detects photometric CL-AGN transitions in 9.6% of known hosts with 1.6% false positive rate from simulations.
High-resolution GRMHD simulations show that tearing of tilted accretion disks around rapidly spinning supermassive black holes drives order-of-magnitude variability in continuum and broad-line luminosities on months-to-years timescales, explaining changing-look AGN.
Radiation hydrodynamic simulations of wind-reprocessed TDEs reveal a ~3-week offset between optical/UV and bolometric light curve peaks due to the buildup time of the reprocessing layer.
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.
Turbulent torques modeled as a Gaussian around the linear torque can push gas-induced dephasing in LISA EMRIs above the detection threshold for Eddington ratios above 0.3 and sufficient turbulence strength.
Multi-mission O-C data on eRO-QPE2 reveal hierarchical super-periods consistent with apsidal precession at a~140 Rg but no robust EMRI solution due to sparse sampling and narrow likelihood peaks.
Quantum hydrodynamic simulation of a helium white dwarf disrupted by a black hole predicts quantized vortices generating flickering EM radiation in the accretion disk and gravitational waves from the elongated white dwarf.
