Sentences with phrase «hole merger occurs»

A black - hole merger occurs when two black holes start to spiral towards each other, radiating energy as gravitational waves.

The Virgo and LIGO detectors found that the new black - hole merger occurred in a patch of sky measuring 60 square degrees.

Not exact matches

If the new model is correct, then such black hole mergers may occur as frequently as once a year somewhere in the Universe.

Each time a merger occurred, material from the new galaxy got incorporated into the accretion disk around the black hole, spinning in the same direction as the black hole and eventually contributing to its growth.

More - stringent tests will be possible if and when LIGO detects black - hole mergers that are larger than this one, or that occur closer to Earth than the Event's estimated distance of 1.3 billion light years, and thus give «louder» waves that stay above the noise for longer.

The first direct detection of gravitational waves occurred in mid-September 2015 (but announced February 11, 2016) with twin LIGO detectors in Hanford, WA and Livingston, LA (both USA) when ripples of spacetime from the last fraction of a second of the merger of two black holes with masses 29 and 36 solar masses combined to form a 62 - solar mass black hole with 3 solar masses of energy radiated away as gravitational waves in that last fraction of a second.

When an energetic event occurs (like a black hole merger or neutron star collision), spacetime becomes violently disturbed and energy is carried away from the event in the form of gravitational waves — like ripples traveling across the water's surface after dropping a pebble in a pond.

This is eventually offset by the many black hole mergers and «feasts» that Priya talked about that occur during the first billion years.
