Derives large-eccentricity asymptotics for post-Newtonian eccentric waveform Fourier modes and builds a fast endpoint-constrained analytic approximation with error under 10^{-3} valid to p=200.
Scalarized Kerr-Newman black holes develop an inner photon shell that produces an additional critical curve and distinct crescent-like higher-order images unlike those in Kerr spacetime.
Amortized neural posterior estimation reproduces nested sampling constraints on RMF couplings for neutron-star EOS with no bias and generates 30,000 samples in 2.5 seconds.
Stellar feedback regulates radial gas inflow in the Milky Way center, yielding time-averaged rates that fall from 5e-3 to 1e-6 solar masses per year with both smooth secular and episodic components.
Two z~6.6 galaxies host overmassive black holes and show remnant ionized bubbles from recent quasar episodes, with BH-to-stellar mass ratios 400-800 times above the local relation.
FRB dispersion measures directly constrain suppression of the matter power spectrum due to feedback at k ~ 0.1-3 h/Mpc, reduce posterior variance by a factor of ~8 at k~1 h/Mpc, and exclude extreme large-scale feedback scenarios at ~2 sigma.
RIAF polarized-transfer models of six poloidal field geometries show Faraday-conversion-dominated, polarity-invariant CP for radial/parabolic fields and emission-dominated, polarity-sensitive CP for dipole/vertical fields; ALMA’s negative V_net excludes reversed fields at high inclination.
SN peculiar velocities combined with Planck CMB yield simultaneous constraints on σ8, γ and Ωk, with ~2σ preference for positive curvature and GR-consistent growth.
EarthSight reduces average compute time per image by 1.9x and 90th-percentile end-to-end latency from 51 to 21 minutes by distributing inference decisions between orbit and ground with shared backbones and early rejection filters.

Water-rich formation produces CH4- and CO2-rich atmospheres while water-poor formation produces carbon-depleted ones, with soot boosting methane; the H2O/CH4-MMW plane diagnoses formation environment for JWST targets.
SIREN is a ~100k-parameter Transformer that detects SIRs with ROC-AUC 0.93 on held-out data and attributes 24% importance to proton density and 13-17% to transverse velocity, identifying flow deflection as a consistent signature.
Presents a curvature-based perturbative method for photon spheres, massive particle surfaces, and black hole shadows that handles mass variations and claims new results for the time-like case.
A perturbative analytical model of gravitational waves on an exact Bianchi IV background is derived via the proper-time method and shown to be stable.
Different parametrizations of density dependence in covariant density functionals produce significant variations in the high-density equation of state and symmetry energy, with rational-function forms providing flexibility when saturation properties are adjusted and constrained by multimessenger ast
