The observatory's detection of two double-black-hole collisions in its first four months of operation after the upgrade suggests that the observatory will be seeing more of these events in the ...

Supermassive black holes reside at the center of most, if not all, massive (and possibly low-mass) galaxies. They range in size from millions to billions of solar masses, and they can eat ...

Since each galaxy hosts a single massive black hole, the resulting single galaxy should end up with two. In practice, however, astronomers haven't found many double black holes. One popular ...

Astronomers have caught a massive black hole letting out a "double burp" after bingeing on hot gas. When cosmic gas comes near one of these sinkholes, it gets sucked in - but some of the energy is ...

NASA has released three new pieces of cosmic sound that are associated with the densest and darkest members of our universe: ...

an astronomer at the Max Planck Institute for Extraterrestrial Physics and the co-author of a study of the double black hole. “This is the aftermath of two galaxies that collided sometime in the ...

To solve this, a trio of scientists from Harvard University and Princeton proposed a "double trace deformation" that can hold a bridge between two black holes open. Previous theories have posited ...

NASA scientists have been capturing sounds across the universe, from the screams of black holes to the gassy outbursts of distant stars. By Tatyana Woodall Published May 20, 2022 2:15 PM EDT Get ...

We study the formation of coalescing black-hole binaries using ... classical formation model for double compact objects composed of two black holes (BH–BH), two neutron stars (NS–NS), or ...

More massive stars than the Sun have a very different life cycle and follow the right hand path in the diagram above: \(\begin{equation} \begin{aligned} Nebula \rightarrow protostar \rightarrow ...
