Latest X-shaped radio galaxy Stories
Observations with CSIRO's Australia Telescope Compact Array have confirmed that astronomers have found the first known "middleweight" black hole.
Two UK astronomers have found that the giant black holes in the center of galaxies are on average spinning faster than at any time in the history of the Universe.
Scientists have found evidence that a giant black hole has been jerked around twice, causing its spin axis to point in a different direction from before.
Black holes are thought to reside at the center of almost every galaxy, with some growing to more than a billion times the mass of the Sun.
A survey by the Chandra X-ray observatory has revealed in detail, for the first time, the effects of a shock wave blasted through a galaxy by powerful jets of plasma emanating from a supermassive black hole at the galactic core.
Two enormous black holes appear to be orbiting one another at the center of a faraway galaxy, formed by the collision of two separate galaxies.
Astronomers are hunting an elusive target: rogue black holes that have been ejected from the centers of their home galaxies.
Using a new computer model of galaxy formation, researchers have shown that growing black holes release a blast of energy that fundamentally regulates galaxy evolution and black hole growth itself.
