In a paper <a href=\"https:\/\/arxiv.org\/abs\/1703.10173\">to be published<\/a> in <i>Monthly Notices of the Royal Astronomical Society<\/i>, a research team from Australian National University, Swinburne University of Technology, University of Sydney and the ARC Centre of Excellence for All-sky Astrophysics (CAASTRO), has confirmed the FRBs do in fact originate from outer space and \u2013 in some cases, at least \u2013 from galaxies beyond the Milky Way.<\/p>\n<p>The research team, headed by PhD candidate and first author Manisha Caleb, has successfully identified the origin of three distinct FRBs.<\/p>\n<p>The use of the updated Molonglo telescope (UTMOST) \u2013 a 778-metre-long parabolic cylindrical antenna array comprising a total of 352 independent antennae, with 7,744 ring antennae at the focus of the parabola \u2013 overcomes the limitations of the single-dish radio telescopes such as Parkes that initially detected FRBs as one-off events.<\/p>\n<p>\u201cSingle-dish antennas have difficulty establishing that transmissions originate beyond Earth\u2019s atmosphere,\u201d explains researcher Dr Chris Flynn of Swinburne\u2019s Centre for Astrophysics and Supercomputing.<\/p>\n<p>The Molongo antennae\u2019s enormous focal length, however, has enabled researchers to use the technique of interferometric detection to calculate the minimum distance of FRBs.<\/p>\n<p>&#8230;&#8230;&#8230;.<\/p>\n<p>Caleb, who led the work developing software to do that sifting, explains that UTMOST detects only events more than 10,000 km away, thereby ruling out terrestrial sources of interference as an origin for FRBs.<\/p>\n<p>\u201cThe telescope has literally been reborn and transformed exclusively to search for these Fast Radio Bursts,\u201d she says. \u201cWe have scientifically confirmed that FRB\u2019s are extra-terrestrial.\u201d<\/p>\n<p>With funding from the Australian Research Council (ARC), the Molonglo telescope will upgraded over the next two years to enable the localisation of FRBs to individual galaxies.<\/p>\n<p>\u201cFiguring out where the bursts come from is the key to understanding what makes them,\u201d Caleb says. \u201cOnly one burst has been linked to a specific galaxy.\u201d<\/p>\n<p>That burst, identified by the Arecibo Observatory in Puerto Rico, was only able to be localised as the only FRB known to have been repeated. In future UTMOST should be able to identify the host galaxy of a burst without repeat events.<\/p>\n<p>\u201cWe expect Molonglo will do this for many more bursts,\u201d Caleb says.<\/p>\n","protected":false},"excerpt":{"rendered":"<p class=\"excerpt\">. &nbsp; https:\/\/cosmosmagazine.com\/space\/born-again-australian-telescope-solves-mystery-of-intergalactic-fast-radio-bursts &nbsp; .
