New JWST and Keck data on off-nuclear TDE 2025abcr show shifting emission-line velocities from a changing reprocessing layer and an IR power-law slope of -2.13 that is consistent with either reprocessing gas or a young stellar cluster of mass ~10^7.6 solar masses.
High-resolution SPH simulations show that significant in-plane spreading and dissipation of returning tidal debris at pericenter is a low-resolution numerical artifact, supporting circularization via later stream-stream collisions instead.
SPH simulations of zero-energy partial TDEs find fallback ~t^{-9/4}, optical luminosities 10^{42-44} erg/s at 10^4 K and radii 10-100 au, indicating many detected TDEs may be partial rather than full.
Multi-epoch spectroscopy of 33 ECLEs shows coronal lines emitted at intermediate radii with log(distance)-log(black hole mass) slopes of 0.63 and 0.69 for [O III] and [Fe VII], consistent with photoionization setting the radii.
Anomalous pre-intersection dissipation in TDE simulations is numerical in origin, arising from pericenter kinematics combined with algorithm sensitivities to converging versus diverging flows.
Pair production via radiative magnetic reconnection near spinning black holes supplies non-uniform plasma to jets at levels sufficient to explain M87 radio emission.
SCAT DR1 delivers 1810 spectra of 1330 transients with classifications, fitted light curves, new redshifts for many host galaxies, and host properties as a testbed for photometric classification pipelines.
LSST will image 18,000 square degrees of sky about 800 times across six bands over 10 years to a coadded depth of r~27.5, producing a public database of 40 billion objects and 32 trillion observations.
Radiation hydro simulations produce black hole mass and viewing angle dependent bolometric correction factors (tens to thousands) and radiative efficiencies (0.001-0.1) for super-Eddington TDE flows that alleviate the missing energy problem when applied to specific events.
The Via Project is a planned five-year dual-hemisphere spectroscopic survey targeting over 2 million stars with 100 m/s RV stability and transient spectroscopy to r~24 using instruments on MMT and Magellan/Clay telescopes starting in 2027.
3D hydro simulations show that TDE outflow interactions with a broken power-law CNM can reproduce the range of observed radio light curves via early flares inside the Bondi radius and possible late rebrightenings outside it.
Numerical geodesics show narrow deflection angles for massive particle scattering off RN black holes versus isotropic scattering off naked singularities.
GRRMHD simulations of CEM-adapted tori find thermal instability in 17-46 days with spin-dependent X-ray decline and soft excess matching AT2021ehb observations.
