Astronomers at the CHIME Observatory in Canada have captured fast radio bursts (FRBs) occurring less frequently than previous FRBs.

Fast Radio Bursts (FRBs), which are incredibly short but very powerful radio wave emissions, were only discovered by scientists in 2007 – specifically by Duncan Lorimer and one of his students, David Narkiewicz, who works at the University of Virginia in the United States. Experts are still debating exactly what causes them, but it turns out we can actually distinguish between two basic types: one that can be associated with a one-time event, and one that recurs continuously.

However, according to researchers at the Canadian Observatory for Hydrogen Intensity Mapping Experiment (CHIME), this may not be the case. During their observations, the experts doubled the number of known replicating FRBs: they discovered 25 new ones in addition to the 21 already known. In addition, another 14 signals are still being observed, but there is a good chance that they may also be repeating FRBs.

This is now ArXiv In their study posted on a preprint server, they write that the big difference between the 25 FRBs just discovered and the 21 previously known FRBs is that the former is much less active. The previously detected fast radio bursts are thought to be emitted by objects such as neutron stars orbiting a heavier object.

Some neutron stars – magnetars – have incredibly strong magnetic fields. The interaction of the magnetic field between them and their companion object results in FRBs.

Of the 25 FRBs just discovered, only 12 emissions have been measured even at their most energetic, making detection and more comprehensive study very difficult. So the researchers want to continue the observations, which they do 24 hours a day with the observatory.

Researchers want to know why some FRBs occur more frequently and others less frequently. According to their assumption, starting from this, all FRBs are recurring, we don’t pay attention to them long enough to catch new and new events.
