A team of scientists headed by Shivani Bhandari, an astronomer with the Commonwealth Scientific and Industrial Research Organization (CSIRO), Australia’s federal agency responsible for scientific research, has made a breakthrough discovery by pinpointing the precise location of four fast radio bursts (FRBs).
FRBs are very mysterious bursts of radio waves coming from somewhere in the universe. The average pulse ranges for a few milliseconds, caused by high-energy sources, which are not entirely understood.

Bhandari’s new research, published on June 1 in The Astrophysical Journal Letters, reveals that four FRBs came from massive galaxies forming new stars. They said FRBs originated not from the center of galaxies, but rather from the outer edges.
“These precisely localized fast radio bursts came from the outskirts of their home galaxies, removing the possibility that they have anything to do with supermassive black holes,” said Bhandari.
Bhandari’s team found exact locations for FRB 180924, FRB 181112, FRB 190102, and FRB 190608 by using the Australian Square Kilometre Array Pathfinder (ASKAP) radio telescope in Western Australia.
