Astronomers discover 83 supermassive black holes in the early universe

Astronomers from Japan, Taiwan, and Princeton University have discovered 83 quasars fueled by supermassive black holes formed when the universe was only 5 percent of its present age was. Here you can see the impression of an artist of a quasar. In the middle is a supermassive black hole, and the gravitational energy of the resulting material is released as …

"The Invisible Galaxy" – 100 Million Black Holes Lurking in the Milky Way (Weekend Feature)

Posted on 02.03.2019 Astrophysicists have discovered a dozen black holes that have accumulated around Sagittarius A * (Sgr A *), the supermassive black hole in the center of the Milky Way, which supports a decade-old prediction and opens new opportunities to better understand the universe. After undertaking a cosmic inventory to calculate and categorize black holes with star remnants, astronomers …

New Supercomputer Simulation Show How Plasma Jets Escape Black Holes

Visualization of a general relativistic collisionless plasma simulation. Image: Parfrey / LBNL Researchers use one of the world's most powerful supercomputers to better understand how high energy plasma escapes the intense gravity of a black hole, which swallows everything else in its path-including light. Before and after a black hole there's no return-a boundary known as the "event horizon" -and …

Astronomers have discovered how supermassive black holes are getting so big

Absolute Unit At the center of our Milky Way is a supermassive black hole several million times more massive than our Sun. Until recently, scientists were not sure how these gigantic black holes got to these ridiculous features proportions. By and large, astronomers assumed that they did so by feeding on their habitual cosmic diets of wayward stars and other …
