In a paper published in Science, Bannister et al. describe
observations with ASKAP to determine the precise location of a Fast
Radio Burst (FRB). A real-time search pipeline identified the
milli-second duration burst in the data 281 ms after its arrival,
triggering the download of several seconds of buffered data containing
the burst. Subsequent processing of that data allowed the FRB to be
localised to the outskirts of a Milky Way-sized galaxy about 3.6
billion light-years away.
The FRB itself is shown in the image above (where the burst has been
de-dispersed, i.e., the arrival times at all frequencies are the same).
Two bands around 1200 MHz are regions flagged due to radio-frequency
interference in the data.
The strong spectral modulation is similar to the previous FRBs
detected with ASKAP, suggesting that they belong to the same population.
