Gravitational waves provide new window on the universe
... objects (just a few times that of the Schwarzchild radius), is further proof that GW150914 is due to a binary black hole merger. Future research We have reached a new step in astrophysics with the very first detection of gravitational waves. Without...

Latest gravitational wave catalogue details 35 new detections
... Around 32 of the events were most likely to be caused by black hole mergers – two black holes spiralling around each other that finally join together. Several of the black holes formed from these mergers exceed 100 times the mass of our Sun, and are...

Black hole collision may have exploded with light
... waves - ripples in space and time that can be detected with extremely sensitive instruments on Earth. Since black holes and black hole mergers are completely dark, these events are invisible to telescopes and other light-detecting instruments used...

Three massive black holes caught in the act of merging
When astronomers made the first observation of a binary black hole merger in February 2016, it was not just gravitational waves that were caught rippling through Earth; a wave of feverish ...

Using gravitational waves to search for Population III stars
... GW150914 is of primordial origin, in addition their studies estimate that aLIGO will detect roughly 1 primordial black hole – black hole (BH – BH) merger per year when modifications to aLIGO have been implemented later this year, although this rate...

A scientific breakthrough as gravitational waves detected for the first time
... with masses of ~36 and ~29 times greater than the mass of our Sun and while numerous black hole candidates have now been identified, black hole mergers have not previously been observed. “This is transformational,” said Prof Alberto Vecchio, of the...
