VAPOLA releases multi-epoch multi-band ALMA full-Stokes products and polarimetric fits for AGN and Sgr A* via an automated pipeline and web portal.
Machine learning on simulated images identifies that flux eruption events cause more diffuse, polarized, lower-flux millimeter emission with decreased Q-U loop rotation rate, achieving ~80% accuracy with random forests on summary statistics.
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.
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.
Derives an electrically charged generalization of the Kiselev black hole metric and studies charged particle orbits, finding prograde periapsis shifts for uncharged particles but possible retrograde shifts for charged ones.
Some opacity in black hole imaging methods is compatible with reliable inference under specified conditions, but GRMHD models of Sgr A* exhibit problematic opacity that signals model limitations.
Simulations of accreting black holes in standard and complex spacetimes indicate that magnetic geometry, quantum corrections, and binary dynamics influence flares, precession, photon rings, and multi-wavelength variability, with potential EHT constraints.
Synthetic EHT data from semi-analytic jet models show that the 2022 array configuration enables robust recovery of faint horizon-scale jet emission in M87* when jet intensity exceeds a determined lower limit.
EHT angular diameter data yield upper bounds on the holonomy correction b (e.g., b ≤ 0.1319M at a=0 for M87*) showing nonzero b remains consistent with observations for RHCBH spacetimes.
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.
