CHIBI is a new hierarchical Bayesian method for multifrequency synthesis radio imaging based on synchrotron spectral parametrization, demonstrated on VLBA MOJAVE data and simulated EHT observations of M87*.
Pair production via radiative magnetic reconnection near spinning black holes supplies non-uniform plasma to jets at levels sufficient to explain M87 radio emission.
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.
Numerical geodesics show narrow deflection angles for massive particle scattering off RN black holes versus isotropic scattering off naked singularities.
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.
A review of Faraday Rotation Measure Synthesis techniques and SKA Array Assembly stages for high-resolution Faraday tomography of cosmic magnetic structures.
A workshop report recommends anomaly detection on existing telescope data to search for technosignatures from advanced minds powered by supermassive black holes.
