M87's radio core shows a proper motion of 10.19 μas yr⁻¹ at position angle 189.2°, implying a tangential velocity of 787 km s⁻¹ and a peculiar velocity of ~1037 km s⁻¹ at 65° to the line of sight.
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.
In general LTB dust collapse the photon surface is a null hypersurface generated by outgoing radial null geodesics that reaches the central singularity if and only if the singularity is naked.
EHT dimensionless shadow diameters plus stellar-dynamical mass priors constrain Einasto central density to ρ₀ ≲ 10^{-11} M⊙/pc³ (1σ) for Sgr A*, with weaker bounds for M87*.
Derives clock-limited VLBI S/N expression and evaluates real and emerging frequency standards for high-frequency space VLBI.
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.
