Sentences with phrase «supermassive black hole binaries»

This will open up an entirely new window into the gravitational - wave universal, allowing us to understand galaxy evolution, and is currently the only known way in which we can study supermassive black hole binaries, and how they formed.

The number of individual supermassive black hole binaries seen also offers a measure of how often galaxies merge, which is an important measure of how the universe evolved over time.

Waves from binary supermassive black holes oscillate slowly compared with supernovas, which generate high - frequency waves.
