Approximately 10% of active galactic nuclei exhibit relativistic jets, which are powered by accretion of matter onto super massive black holes. While the measured width profiles of such jets on large scales agree with theories of magnetic collimation, predicted structure on accretion disk scales at the jet launch point has not been detected. We report radio interferometry observations at 1.3mm wavelength of the elliptical galaxy M87 that spatially resolve the base of the jet in this source. The derived size of 5.5 +/- 0.4 Schwarzschild radii is significantly smaller than the innermost edge of a retrograde accretion disk, suggesting that the M87 jet is powered by an accretion disk in a prograde orbit around a spinning black hole.

  1. Dark matter environments and safeguards for spacetime inference from horizon scale interferometry

    gr-qc 2026-07 conditional novelty 6.0

    Using public 2017 M87* closure data, a frozen Kerr source fails an absolute adequacy test and the differential tidal-charge response fails numerical convergence, so no posterior or bound is reported.

  2. Polarization Architecture of Steady GRMHD Jets from the Horizon to Infinity

    astro-ph.HE 2026-07 unverdicted novelty 6.0

    Steady GRMHD jets exhibit a universal near-horizon polarization pattern set only by black hole spin, with large-radius polarization angle following a collimation-determined power law and intermediate scales modified b...

  3. Viscosity effects on the shadow of a non-rotating black hole

    gr-qc 2026-07 conditional novelty 5.0

    Shear viscosity and spacetime-curvature transport alter synthetic black hole shadow images of stationary magnetized tori at the few-μJy level.

  4. Dynamics and geometry of the inner sub-parsec-scale jet in 3C 279 observed with the Event Horizon Telescope

    astro-ph.GA 2026-07 conditional novelty 5.0

    EHT 2021 images of 3C 279 reveal an intrinsic, sideways-elongated jet base whose components move at apparent speeds up to 10c, implying a sub-parsec bend toward the observer and viewing angles below one degree.
