First discovered in 2007, FRBs (or FRBs – Fast Radio Burst) still hide many mysteries. Of unknown and unpredictable origin, these flashes of light are observed with interest by a new generation radio telescope, in order to learn more about these phenomena coming from remote regions of the universe as well as from our galaxy.
radioscope Beating (Canadian Hydrogen Intensity Mapping Experiment), based in southwest Canada, identified 535 fast radio bursts in one year of operation, thus completing the catalog — limited — for the first 140 observed since 2007. “To see a fast radio burst, you have to be very lucky. Regarding where and when to aim your radio dish,” MIT says in a published statement June 9. You also have to be fast, because these flashes “fire for a few milliseconds before disappearing without leaving a trace”. However, there are many more, about 800 per day across the sky, according to an MIT estimate.

Scientific studies using CHIME made it possible to develop an “index” of the FRB of the telescope, which was presented during the conference of the American Astronomical Society. It will make it possible to “significantly” expand the existing library on FRBs and deepen knowledge of their properties. Thus, the latest study made it possible to highlight two types of fast radio bursts: those that are recurring and isolated instances. “These observations strongly suggest that repeats and colons arise from separate astrophysical mechanisms and sources,” MIT explains. Further studies to come should help determine the origins of these bright signals.
Unlike most radio telescopes, which rotate to focus light from the sky, CHIME is a fixed, fixed array, made up of four cylindrical radio antennas. Using a telescope to detect FRBs should also allow us to map the distribution of gas in the universe.
