A reference-frequency-independent detection statistic for eccentric binary mergers is introduced and applied to GW200105, yielding ln B ≤ 0.9 in favor of the eccentric aligned-spin model over the quasi-circular precessing model.

A parametrized analytical model for BBH mass ratios from the stable mass transfer channel is derived and applied to the 10 solar-mass peak in GWTC-4, favoring little mass-ratio reversal.
MSW resonances in collapsing supermassive stars swap neutrino flavors adiabatically in the normal hierarchy for neutrinos and inverted hierarchy for antineutrinos, altering the initial 5:1 electron-to-muon/tau flux ratio.
A 4200-hour campaign on FRB 20240114A finds that the highest-energy bursts account for most of the observed radio energy release, with a break in the energy distribution at ~2×10^40 erg and a linear DM rise of +0.96 pc cm^{-3} over 318 days.
Large N-body galaxy simulations reveal high chaos with Lyapunov times that extrapolate to Milky Way galaxies being chaotic on timescales ≲ 0.1 Myr.
GW250114 data confirm the remnant black hole ringdown frequencies lie within 30% of Kerr predictions and that the final horizon area is larger than the sum of the progenitors' areas to high credibility.
Combining LRG and ELG tracers with bias weighting improves BAO constraints by 11% on alpha_iso and 7% on alpha_AP in DESI DR1 data for the 0.8<z<1.1 bin.

Neutrino Flavor Transformation in Collapsing Supermassive Objects

A 4200-hour HyperFlash and \'ECLAT campaign on the hyperactive FRB 20240114A: constraining energetics with the most brilliant bursts
A 4200-hour campaign on FRB 20240114A finds that the highest-energy bursts account for most of the observed radio energy release, with a break in the energy distribution at ~2×10^40 erg and a linear DM rise of +0.96 pc cm^{-3} over 318 days.
