A simulation showed black holes with masses between 100 and 10,000 times that of the sun could be born through a chaotic ...

Scientists have discovered strong evidence that some massive stars end their existence with a whimper, not a bang, and sink ...

This artist's concept illustrates a supermassive black hole with millions to billions times the mass of our sun. Supermassive ...

Joint research led by Michiko Fujii of The University of Tokyo demonstrated a possible formation mechanism of ...

These stellar black holes must exist in the millions ... so-called intermediate-mass black holes. These objects range from hundreds to hundreds of thousands of solar masses, and evidence for ...

"The ratio of stellar mass to black hole mass in early galaxies was much lower back then, more than a dozen billion years ago ...

While the life cycle of stars is well understood, there are still many mysteries surrounding their collapse and spectacular ...

Clemson University astrophysicists believe they have discovered a rare black hole system, containing two black holes, in ...

Astronomers have a new way to measure how fast a black hole spins, by using the wobbly aftermath from its stellar feasting ... estimates of the black hole's mass, and that of the disrupted ...

New research utilizes the first-ever simulations of individual stars in forming globular clusters to explore potential ...

(It’s weird and rather fun that one piece of evidence for the existence of black holes is when we don’t see them.) Around the same time Cygnus X-1 was shown to be a stellar-mass black hole ...

Researchers have discovered that elusive intermediate-mass black holes could form in dense star clusters containing anywhere between tens of thousands to millions of tightly packed stars called ...
