Astronomers have pinpointed the location of a repeating fast radio burst, Astronomers in Europe, in collaboration with BRIM members of the Canadian radio collaboration BRIM, have identified the location of repeated high-speed radio blasts (FRB) that were first discovered by the 2018 CHIME telescope in British Columbia.
This breakthrough is only the second time that scientists have pinpointed the exact location of the recurring source of this millisecond space wave explosion. Researchers have reached a resolution high enough to find FRB in an area of about seven light years comparable to individuals on Earth who can distinguish a person from the moon.
“We used Gemini North, Hawaii, an eight meter telescope to take sensitive pictures showing galaxies of weak Milky Way arms, showing that the FRB source was in one of these arms in the star-forming region, the researcher said.
With more than 1000 antennas, CHIME’s wide field of view offers a far better chance of getting volatile eruptions than conventional radio telescopes, each of which can only observe a small area in the sky. When determining FRB 180916, the CHIME / FRB team worked closely with its EVN counterparts to determine exactly where the VLBI telescope should be directed.
By recording and processing raw signals from each antenna element that forms CHIME, we can improve the position of the source to a level close enough to the EVN to observe and find some bursts from the FRB source.
Half a billion light years from Earth, source FRB 180916 is about seven times closer than the only other local explosion and more than ten times closer than some repeated FRB scientists did.
This is interesting for astronomers because it will allow for more in-depth studies that can help limit possible explanations for FRB. We have a new opportunity to capture emissions from other wavelengths – X-rays or visible light, researchers say. Leading member of the CHIME / FRB collaboration. And if we do that, it will be very limiting for the model.
