First Sagittarius A* Event Horizon Telescope Results. I. The Shadow of the Supermassive Black Hole in the Center of the Milky Way

Kazunori Akiyama, +387 more
- 01 May 2022 - 
TL;DR: The first Event Horizon Telescope (EHT) observations of Sagittarius A* (Sgr A*), the Galactic center source associated with a supermassive black hole, were conducted in 2017 using a global interferometric array of eight telescopes operating at a wavelength of 1.3 mm as mentioned in this paper .
Journal ArticleDOI

First Sagittarius A* Event Horizon Telescope Results. VI. Testing the Black Hole Metric

Event Horizon Telescope Collaboration, +270 more
- 01 May 2022 - 
TL;DR: In this article , the authors calibrate the relationship between the geometrically defined black hole shadow and the observed size of the ring-like images using a library that includes both Kerr and non-Kerr simulations.
Journal ArticleDOI

Shadows of spherically symmetric black holes and naked singularities

Rajibul Shaikh, +4 more
- 01 Jan 2019 - 
TL;DR: In this paper, the authors compare shadows cast by Schwarzschild black holes with those produced by two classes of naked singularities that result from gravitational collapse of spherically symmetric matter.
Journal ArticleDOI

Event Horizon Telescope Collaboration, +270 more
- 01 May 2022 - 
TL;DR: In this article , the authors presented the first event-horizon-scale images and spatiotemporal analysis of Sgr A* taken with the Event Horizon Telescope in 2017 April at a wavelength of 1.3 mm.
