First M87 Event Horizon Telescope Results. I. The Shadow of the Supermassive Black Hole
K. Akiyama · The Event Horizon Telescope Collaboration (K. Akiyama et al.); large multi-institution collaboration.
Summary
This is the first paper in the Event Horizon Telescope (EHT) series presenting the first image of a supermassive black hole, located at the center of the galaxy M87. Using global very long baseline interferometry at 1.3 mm, the collaboration resolved a bright ring of emission surrounding a central dark region, the black hole shadow. The observations are consistent with a Kerr black hole of mass about 6.5 billion solar masses.
Key findings
- Produced the first direct image of a black hole's shadow, in M87.
- Measured an asymmetric emission ring of about 42 microarcseconds diameter.
- Inferred a central black hole mass of approximately 6.5 billion solar masses, consistent with general relativity.
