Sentences with phrase «like black hole mergers»

Being able to study things like black hole mergers through gravity will shed light on some of the «darkest yet most energetic events in our universe,» said Albert Lazzarini, deputy director of the LIGO Laboratory, in an American Physical Society press release.

LIGO's detection of this event, plus another, fainter signal that also looks like a black hole merger, means we can conclude that black hole binaries this size can and do form in nature.

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.

Not exact matches

A black hole merger in a massive galaxy like M87 would yield detectable gravitational waves for 4 million years, for instance, while a more modest galaxy such as the Sombrero Galaxy would offer a 160 - million - year window.

The other aspect is that space - time is incredibly stiff: that's why you need a cataclysmic event like the merger of two black holes to produce a distortion that we can measure.

A year ago, LIGO confirmed a prediction made by Albert Einstein a century earlier: that violent cosmic events, like the merger of two black holes, would wrench the fabric of spacetime and emit ripples.

Supermassive black holes like the one in galaxy M87 probably grow not only by feeding on infalling gas and stars but also by mergers of smaller black holes.

That's because no one knows whether such supergiants grow from scratch within star - forming regions, or whether, like supermassive black holes and galaxies, they reach their enormous mass through mergers.

Gravitational waves are ripples in space - time caused by events like the merger of two black holes.

Other theories, like mergers of smaller black holes, remain viable, and researchers aren't quite sure yet how many black holes there really are in the early universe.

If galaxies that have never been through a merger, like NGC 4178 — detectable by their lack of stellar bulges — have their own central black holes, their properties could help tell the story.

Like the historic first detection announced this past February, these gravitational waves were also generated by the merger of two black holes.

Mészáros notes that the gravitational waves looked like they came from objects smaller in mass than black holes, which pointed to neutron stars, and that the electromagnetic emissions separately correlated to the event provide two ways to show proof - positive that this is a neutron star merger.

The group in which he works is involved in the instrumental development for the LISA PathFinder mission (ESA), a technology precursor mission for a future space - based gravitational - wave observatory, LISA, which will detect the gravitational radiation from low frequency sources like massive black hole mergers, inspiraling stellar compact objects into massive black holes, and galactic binaries.

The increasing amplitude and frequency of the waves during the merger if converted to audio sound waves would make a sound like a chirp of a bird, so the LIGO scientists refer to it as the chirp of a black hole merger.

This latest detection originated from a merger creating a black hole of 49 solar masses (another «heavy» black hole like the first one), but the merger happened over twice as far away than previous events.

Indian scientists made direct contributions — ranging from designing algorithms used to analyse signals registered by detectors to ascertain those from a gravitational wave to working out parameters like estimating energy and power radiated during merger, orbital eccentricity and estimating the mass and spin of the final black hole and so on.
