After the experiment, there was no radio signal in the low frequency band.
Fast radios (FRBs) are signals that come from an unknown source in deep space. They were first recorded in 2007. Since then, several dozen such outbreaks have been reported.
FRBs are supposed to be the consequences of a large amount of energy release. They only last a few milliseconds and identify the source of their origin difficult.
A team of scientists from the Australian University of Painters, led by Marcin Sokolowski, found that FRB was not observed at low frequencies. Scientists have sent the same patch of two telescopes: MWA and CSIRO Australian SKA Pathfinder. It was used to detect dozens of deep-space signals written in Nature. But at that time, like ASKAP, they discovered a new FRB, the second telescope did not notice anything.
"When ASPAP sees these exceptionally clear events and MWA – no, it tells us that there is something really unexpected, or fast radio broadcasting that is not broadcast at low frequencies or signals blocking on the way to the ground," Sokolowski said.
Scientists were able to track one FRB of dwarf galaxies three billion light-years from Earth. The signal was repeated, which is very unusual. All other FRBs were one-off events and watched their work.
