Astronomers discover powerful fast radio bursts impaling nearby galaxies and help find dark matter

Many astronomers think they are emitted by neutron stars. The density and magnetic field strength of these very compact stars are unique in the universe. Now they have become a tool that measures the concentration of dark atoms in the galaxies it passes through
In the figure, Australia's main science agency CISRO's ASKAP radio telescope detected a fast radio burst and determined its exact location. Ground-based telescopes around the world, KECK, VLT and Gemini, were then directed to follow-up observations of the galaxy where the event occurred. CSIRO / Andrew Howells

The image on the left taken in infrared shows the field of view of the Parkes radio telescope with the area where the event occurred marked in red. On the right, a successive series of close-ups of the area. At lower right is the visible-light image of the galaxy where the burst occurred, as taken from the Subaru Telescope in Hawaii, with the elliptical regions showing the location of signals that faded over six days as seen with ATCA Credit: © D.
