Boffins on alert: Brace yourselves for huge gravitational wave coming within a decade

The most violent gravitational waves in the universe from supermassive black hole prangs will be detected to within ten years, according to research published on Monday. Gravitational waves were predicted by Albert Einstein and finally discovered in 2015, a century after his theory of general relativity was formalized. Ripples …

Neutron stars shower gold on universe in big bang, felt on Earth as 100-second grav wave

Barely two years after it came online, the Laser Interferometer Gravitational-Wave Observatory (LIGO) has scored a double success. Last week, the instrument earned its creators a Nobel Prize – and this week we're told it helped spot the first neutron star collision from both its gravitational wave and radiation emissions. At …

Did the Earth move for you, too? Grav waves sensed from black holes' bang 1.8bn LYs away

Scientists have recorded the most accurate reading of gravitational waves yet by using the upgraded LIGO and Virgo observatories together for the first time. The ripples were detected on August 14 at the Laser Interferometer Gravitational-wave Observatories (LIGO) in Louisiana and Washington state in the US, and the Virgo …

Swinburne Uni slings SGI, picks DellTel for new 4,140 core super

Australia's Swinburne University has signed up for a new supercomputer, to help spearhead efforts to detect gravitational waves. OzSTAR will be composed of Dell PowerEdge R740 servers each packing a single 18-core, 36-thread Xeon Gold 6140, a pair of NVIDIA Tesla P100 12GB GPUs and 192GB RAM. Eight of the 115 nodes in the …

If we're in a simulation, someone hit it with a hammer, please: Milky Way spews up to 100 MEELLLION black holes

A new study shows that there may be up to 100 million black holes scattered around the dark depths of the Milky Way – a number much higher than previously expected. That figure was calculated by University of California at Irvine physicists, who took a closer look at the gravitational waves detected by the LIGO equipment in …

LIGO physicists eyeball a new gravitational wave

Physicists working at the Laser Interferometer Gravitational-Wave Observatory (LIGO) have spotted gravitational waves rippling through the universe for the third time, according to results published in Physical Review Letters on Thursday. The discovery of gravitational waves was announced for the first time in February 2016. …

Riddle of cannibal black hole pairs solved ... nearly: Astroboffins explain all to El Reg

Astrophysicists are one step closer to understanding how pairs of merging black holes form in the far reaches of the cosmos. The dramatic melding of two black holes produced the first gravitational waves detected by the Earth-based Advanced Laser Interferometer Gravitational-wave Observatory (LIGO). While these waves confirmed …

Oz universities plan big iron to look for gravitational waves

A new supercomputer is one of the goodies that Australia's Swinburne University will get in a newly-launched gravitational wave research project. The university's professor Matthew Bailes is leading an AU$31.3 million initiative called OzGRav, and is drawing together local researchers who already have experience in …

BAM! Astroboffins now have a second way of picking up black holes' collision super kicks

Gravitational waves released from black hole “super kicks” may soon be detectable, according to new research published in Physical Review Letters. Einstein realised that gravitational waves were a product of his theory of General Relativity, which found that spacetime behaved like a fabric. When objects with mass – such as …

LIGO team may have found dark matter

Scientists think the recent discovery of gravitational waves observed from the collision of two black holes may have also detected signatures of the astrophysics mystery of dark matter. Scientists at Johns Hopkins university behind the September 2015 discovery by Laser Interferometer Gravitational-Wave Observatory (LIGO) wrote …

Gravitational waves: A new type of astronomy

The first time physicists announced that the Laser Interferometer Gravitational-wave Observatory (LIGO) had detected gravitational waves, on September 14, 2015, it was breaking news. The discovery coincided with the 100-year anniversary of Einstein's theory of General Relativity, which predicted the existence of gravitational …

Laser probers sniff more gravitational waves from mega black hole smash

An international team of physicists has announced that the Laser Interferometer Gravitational Wave Observatory (LIGO) has detected gravitational waves from a second pair of colliding black holes. The genius of Einstein At the start of the year, the scientific community was buzzing with excitement after rumours started …

'Cat-flap' pendulum offers 7x improvement for grav-wave detectors

A University of Western Australia (UWA) boffin who played a major part in Australia's contribution to finding gravitational waves reckons detectors can get a lot more sensitive. UWA Professor David Blair, who discussed how quantum noise can interfere with gravitational wave detection with Vulture South in 2011, has supervised …

CSIRO says it hasn't sacked the LIGO mirror-makers

In an example of how heated the debate over the much-reduced budget at Australia's Commonwealth Scientific and Industrial Research Organisation (CSIRO) has become, an argument has broken out over whether the division that helped craft mirrors for the groundbreaking LIGO experiment still exists. Mirrors and their calibration …

Boffins' gravitational wave detection hat trick blows open astronomy

Analysis A 15-year experiment using some of the most advanced technology known to Man has picked up the first detection of a gravitational wave, the first direct measurement of black holes, and the first direct evidence of binary black holes. It has also opened up an entirely new field of astronomy. The signal was picked up on …

LIGO boffins set to reveal grav-wave corker

After weeks of speculation, the stage is set for Laser Interferometer Gravitational-wave Observatory (LIGO) boffins to announce their findings. The LIGO Scientific Collaboration has briefly popped its head over the parapet to say it'll come clean about what it has (or hasn't) found on Thursday at the National Science …
