At the beginning of the 21st century it became obvious that using small-diameter (up to one metre) robotic telescopes in astronomy allowed for breakthroughs in observing non-stationary and short-lived events in the Universe. With the help of robotic...
... suggest just a 0.2 percent chance that these beams of intense radiation are a simple random coincidence with the GW150914 event. If it is established that the bursts originated from the same source as the gravitational waves, it would be a landmark...

... are easier to detect. After analysis of their models, the team find a ∼ 1% probability that the current detection GW150914 is of primordial origin, in addition their studies estimate that aLIGO will detect roughly 1 primordial black hole – black...
... false alarm probability of 0.0022. Its localisation was reported as ill-constrained but consistent with the direction of GW150914 and does not appear connected with other previously known astrophysical, solar, terrestrial, or magnetospheric activity...
