Independent analysis reproduces the ring-like shadow around M87's black hole
A Nature study reported that an independent analysis of Event Horizon Telescope data reproduced the ring-like shadow and estimated mass of M87's central black hole.
Researchers used calibration-resistant measurements and a separate imaging method to reanalyze radio-interferometry data from the supermassive black hole M87*.
The study reported a ring-like shadow with a diameter of 42.2 plus or minus 1.5 microarcseconds and an estimated mass of 6.5 plus or minus 0.5 billion Suns under its stated assumptions.
