Calypso is a parameter-conditioned stochastic surrogate model for circumbinary accretion flows using PCA and multivariate Gaussian modeling, released as open-source software with a closed-form likelihood for parameter inference from time series.
Red quasars are intrinsically X-ray weak with low alpha_OX values, tracing a distinct evolutionary stage of suppressed black hole accretion relative to stellar mass growth.
SPHEREx data confirm 77 new luminous heavily reddened quasars at 1.5<z<3.9 that are hot-dust poor relative to unobscured quasars, supporting a blow-out feedback phase.
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.
Targeted PTA searches for CWs from 114 AGN in NANOGrav 15 yr data yield no detections, factor-of-two tighter limits than all-sky searches, and updated constraints ruling out part of the parameter space for a binary in 3C 66B.
ShardTensor is a domain-parallelism system for SciML that enables flexible scaling of extreme-resolution spatial datasets by removing the constraint of batch size one per device.
Low-luminosity AGN exhibit optical variability structure function slopes that increase with black hole mass from ~0.1 to ~0.3, with amplitude anticorrelated with luminosity, no breaks observed, and variability continuing to rise on 20-year timescales.
A new complete gauge fixing at initial data via Hodge decomposition on complete Riemannian manifolds enables existence proofs for Hadamard states in the quantization of Maxwell theory on globally hyperbolic Lorentzian manifolds.
Quasinormal modes for three spin fields on Einstein-Skyrme AdS black holes exhibit a mild overtone anomaly and confirm strong cosmic censorship with Christodoulou parameter β much smaller than 1/2.
Evolved stars with radii ≳500 R_⊙ in nuclear star clusters can eclipse mm radio cores of nearby radio-loud AGN with ~10% relative depth, recurrence times ≳10 years, and durations ~10 days, enabling inference of SMBH masses and NSC composition.
JWST spectroscopy reveals radio jets in nearby AGN drive multiphase ISM turbulence and shock-dominated H2 excitation both along and perpendicular to the jet direction.
The orbital nodal phase Δψ_orb equals the nodal precession per orbit and serves as a pipeline-invariant baseline for Kerr black hole timing in the thin-ring limit.
Numerical simulations show Shannon entropy and MIPP indicators distinguish chaotic from regular orbits of charged particles near weakly magnetized black holes in Einstein-ModMax theory, with parameters restricted by EHT shadow observations.
Bounded polymerization in asymmetric LQG-inspired bounce models makes shell-crossing singularities unavoidable for inhomogeneous dust collapse, whereas unbounded polymerization in non-bouncing models permits avoidance for suitable decreasing initial profiles.
Numerical geodesics show narrow deflection angles for massive particle scattering off RN black holes versus isotropic scattering off naked singularities.
Applies KCC theory for Jacobi stability analysis of geodesics in dynamical Chern-Simons rotating black holes and compares advantages versus Lyapunov stability.
The shadow of a Kerr-Newman-like black hole in Bumblebee gravity with plasma is analyzed via observables and constrained by M87* EHT data, with spin and Lorentz violation mainly distorting the shape while charge and plasma shrink the size.
Dark matter halo parameters amplify the scale of closed timelike orbits in Schwarzschild spacetime, inducing phase lags in gravitational waves while light curves retain distinguishable peaks for certain orbital features.
Bardeen-like black holes produce ℓ-dependent corrections to weak-field deflection and strong-field lensing observables that remain consistent with observations but may distinguish them from Schwarzschild black holes.
GPUmonty delivers a 12x speedup over grmonty by parallelizing superphoton operations on GPUs while keeping errors below 1% in tests against analytic solutions and prior codes.
Stochastic trajectories near Schwarzschild horizons are shaped by gravitational fluctuations, producing different behaviors depending on angular momentum, particle frequency, and integration time.
Derives slow-roll observables and consistency relations for scalar-tensor Gauss-Bonnet inflation and fits a specific model to Planck data.
Numerical on-axis scalar scattering cross sections by Kerr-Newman black holes match classical and semiclassical results.
