An international team of scientists led by an SKA Project Scientist has for the first time managed to identify the location of a fast radio burst using a combination of radio and optical telescopes, allowing them to confirm the current cosmological model of the distribution of matter in the Universe. The results are published in the journal Nature.

On April 18, 2015, a fast radio burst (FRB) was detected by the Commonwealth Scientific and Industrial Research Organisation (CSIRO)’s 64-m Parkes radio telescope in Australia. An international alert was triggered to follow it up with other telescopes and within a few hours, a number of telescopes around the world were looking for the signal, including CSIRO’s Australian Telescope Compact Array (ATCA).

FRBs are mysterious bright radio flashes generally lasting only a few milliseconds. Their origin is still unknown, with a long list of potential phenomena associated with them. FRBs are very difficult to detect; before this discovery only 16 had been detected.

“In the past FRBs have been found by sifting through data months or even years later. By that time it is too late to do follow up observations.” says Dr Evan Keane, Project Scientist at the Square Kilometre Array Organisation and the lead scientist behind the study. To remedy this, the team developed their own observing system at Swinburne University of Technology in Australia to detect FRBs within seconds, and to immediately alert other telescopes, when there is still time to search for more evidence in the aftermath of the initial flash.
