Journal ArticleDOI

First M87 Event Horizon Telescope Results. I. The Shadow of the Supermassive Black Hole

Kazunori Akiyama, +406 more
TL;DR: In this article, the Event Horizon Telescope was used to reconstruct event-horizon-scale images of the supermassive black hole candidate in the center of the giant elliptical galaxy M87.
Journal ArticleDOI

First M87 Event Horizon Telescope Results. VI. The Shadow and Mass of the Central Black Hole

Kazunori Akiyama, +254 more
TL;DR: In this article, the authors present measurements of the properties of the central radio source in M87 using Event Horizon Telescope data obtained during the 2017 campaign, and find that >50% of the total flux at arcsecond scales comes from near the horizon and that the emission is dramatically suppressed interior to this region by a factor >10, providing direct evidence of the predicted shadow of a black hole.
Journal ArticleDOI

First M87 Event Horizon Telescope Results. IV. Imaging the Central Supermassive Black Hole

Kazunori Akiyama, +254 more
TL;DR: In this article, the first Event Horizon Telescope (EHT) images of M87 were presented, using observations from April 2017 at 1.3 mm wavelength, showing a prominent ring with a diameter of ~40 μas, consistent with the size and shape of the lensed photon orbit encircling the "shadow" of a supermassive black hole.
Journal ArticleDOI

First M87 Event Horizon Telescope Results. V. Physical Origin of the Asymmetric Ring

Kazunori Akiyama, +262 more
TL;DR: In this article, a large library of models based on general relativistic magnetohydrodynamic (GRMHD) simulations and synthetic images produced by GRS was constructed and compared with the observed visibilities.
