When black holes collide, the impact radiates into space like the sound of a bell in the form of gravitational waves. But after the waves, there comes a second reverberation—a murmur that physicists have theorized but never ...
Astronomers have confirmed the first known triple system in which all three galaxies host actively feeding, radio-bright supermassive black holes.
Black holes are notorious for gobbling up everything that comes their way, but astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have discovered that even supermassive black holes can be picky eaters, ...
What could force a supermassive black hole (SMBH) out of its host galaxy? They can have hundreds of millions, even billions of solar masses. What's powerful enough to dislodge one of these behemoths?
Most smaller galaxies may not have supermassive black holes in their centers, according to a recent study using NASA's Chandra X-ray Observatory. This contrasts with the common idea that nearly every galaxy has one of these ...
The cosmos has served up a gift for a group of scientists who have been searching for one of the most elusive phenomena in the night sky. Their study, presented in Science Advances, reports on the very first observations ...
A team of astronomers including George Washington University physics Ph.D. student Eliza Neights recorded an extraordinary cosmic outburst this July which likely heralds a new kind of stellar explosion. With a flood of data ...
Intermediate mass black holes (IMBH), if they exist, have between about 100 and 1,000 solar masses, placing them in between stellar black holes and supermassive black holes. But while there's plenty of evidence for both stellar ...
An international team of astronomers, led by SRON, has observed a sudden outburst of matter near the supermassive black hole NGC 3783 at speeds reaching up to 20% of the speed of light. During a 10-day observation, mainly ...
A new study by researchers at the University of Amsterdam shows how gravitational waves from black holes can be used to reveal the presence of dark matter and help determine its properties. The key is a new model, based on ...
