A massive technical upgrade of the Southern Hemisphere’s largest radio telescope in pursuit of an answer to one of modern astronomy’s greatest
puzzles has reaped its first dividends, by confirming the origins of the mysterious bursts of radio energy known as Fast Radio Bursts (FRBs).
FRBs are short, bright and highly dispersed pulses of radio waves that occur randomly. They typically last just a few milliseconds but register
about a billion times brighter than anything ever observed in the galaxy.
Since they were first detected almost 10 years ago by the Parkes radio telescope in New South Wales, these enigmatic radio transients have perplexed
astronomers. While they appeared to come from vast distances, their was still a possibility that their origin was closer to home. Were they signals
from far-off galaxies or simply some unknown form of local interference?
Now, thanks to the extensive upgrade of the Molonglo Observatory Synthesis Telescope (MOST), located about 350 km south of Parkes near Canberra,
there is a definitive answer. In a paper to be published in Monthly Notices of the Royal Astronomical Society, 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 – in some cases, at least – from galaxies beyond the Milky Way.
