Black Holes
Black holes are some of the most fascinating and mind-bending objects in the cosmos. The very thing that characterizes a black hole also makes it hard to study: its intense gravity. All the mass in a black hole is concentrated in a tiny region, surrounded by a boundary called the "event horizon". Nothing that crosses that boundary can return to the outside universe, not even light.

Black holes have the distinct honour of being the most popular and potentially the least well-understood objects in the Universe. This issue's Insight explores how far black hole research has ...

Black Holes: Properties, Formation, and Significance in Astrophysics
This paper delves into the world of black holes, exploring their basic properties, formation, and importance in astrophysics. We discuss the singularity at the center of black holes and the event ...
Black holes
Supermassive black holes of 10 6 -10 9 solar masses have been observed at the centers of many galaxies, and here we discuss the observational challenges that were met to show that there exists a black hole at the center of our own galaxy. Stellar-size black holes of about 3-20 solar masses have been studied in x-ray binaries and microquasars.
[2110.08629] Black holes
Black holes are defined as a region in spacetime where gravity is so strong that particles and electromagnetic radiation cannot escape. According to their mass, they are classified into three types: stellar-mass black holes, intermediate-mass black holes, and supermassive black holes. This entry describes how to weight and detect these three types of black holes, summarizes key research ...

Black Hole Physics and Computer Graphics
Black holes are among the most extreme objects known to exist in nature. As such, they are excellent laboratories for testing fundamental theories and studying matter in conditions that cannot be found anywhere else in the Universe. In this article, we highlight the relevance of black holes in modern physical and astronomical research and present one of the possible paths to explain ...
Physicists observationally confirm Hawking's black hole theorem for the
Researchers from MIT and other institutions have been able to observationally confirm one of Stephen Hawking's theorems about black holes, measuring gravitational waves before and after a black hole merger to provide evidence that a black hole's event horizon can never shrink, reports Caroline Delbert for Popular Mechanics.. "This cool analysis doesn't just show an example of Hawking's ...

[1906.03871] Astrophysical Black Holes: A Review
In this review, I have tried to focus on the development of the field, from the first speculations to the current lines of research. According to Einstein's theory of general relativity, black holes are relatively simple objects and completely characterized by their mass, spin angular momentum, and electric charge, but the latter can be ignored in the case of astrophysical macroscopic objects ...

First detection of light from behind a black hole
The strange discovery, detailed in a paper published July 28 in Nature, is the first direct observation of light from behind a black hole - a scenario that was predicted by Einstein's theory ...

Gravitational lensing by spinning black holes in astrophysics, and in
At a summer school in Les Houches, France, in summer 1972, Bardeen [], building on earlier work of Carter [], initiated research on gravitational lensing by spinning black holes.Bardeen gave a thorough analytical analysis of null geodesics (light-ray propagation) around a spinning black hole; and, as part of his analysis, he computed how a black hole's spin affects the shape of the shadow that ...
[2303.08918] A CEERS Discovery of an Accreting Supermassive Black Hole
We report the discovery of an accreting supermassive black hole at z=8.679, in CEERS_1019, a galaxy previously discovered via a Ly$α$-break by Hubble and with a Ly$α$ redshift from Keck. As part of the Cosmic Evolution Early Release Science (CEERS) survey, we observed this source with JWST/NIRSpec spectroscopy, MIRI and NIRCam imaging, and NIRCam/WFSS slitless spectroscopy. The NIRSpec ...
Inside the black hole
The simplest model of a black hole, the massive point source generating a static spherically symmetric gravitational field, is examined using the Schwarzschild coordinate frame. A brief review is given of this coordinate frame external to the Schwarzschild surface.

[2312.00841] Do Black Holes have Singularities?
There is no proof that black holes contain singularities when they are generated by real physical bodies. Roger Penrose claimed sixty years ago that trapped surfaces inevitably lead to light rays of finite affine length (FALL's). Penrose and Stephen Hawking then asserted that these must end in actual singularities. When they could not prove this they decreed it to be self evident. It is shown ...
