Particle Creation by Black Holes

TL;DR: In this article, it is shown that quantum mechanical effects cause black holes to create and emit particles as if they were hot bodies with temperature, which leads to a slow decrease in the mass of the black hole and to its eventual disappearance.

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.

The Singularities of gravitational collapse and cosmology

TL;DR: In this article, a new theorem on space-time singularities is presented which largely incorporates and generalizes the previously known results and applies if the universe is spatially closed or there is an object undergoing relativistic gravitational collapse (existence of a trapped surface).
Journal ArticleDOI

Black holes in general relativity

TL;DR: In this paper, it is shown that a stationary black hole must have topologically spherical boundary and must be axisymmetric if it is rotating, and these results together with those of Israel and Carter go most of the way towards establishing the conjecture that any stationary blackhole is a Kerr solution.

Oscillatory approach to a singular point in the relativistic cosmology

TL;DR: In this article, an oscillatory approach to a singular point in the relativistic cosmology is presented, where the point is represented as a point in a circle of light.
