As it might be known, one of the defining features of the strange deep-space waves we dubbed fast radio bursts is that they are irregular. They belch out across the universe without synchrony or reason, with no distinct model, becoming extremely challenging to examine.
According to a recent study, however, some things might change a little bit. Astronomers succeeded in identifying a quick radio burst, also known as FRB, that repeats on a constant cycle. So, for every 16,35 days, the signal, now titled FRB 180916.J0158+65, realizes a similar path. For four days, it will dismiss a blast or two/hour. After that, it becomes silent for almost 12 days. Then all repeats.
Astronomers utilized the CHIME (the Canadian Hydrogen Intensity Mapping Experiment) to analyze the 16-days cycle for 409 days. Their research is still missing some significant pieces, but it could be another part of the complex puzzle of FRBs. What are these radio bursts? They’re immensely energetic flashes of radiation in the radio spectrum that persist only a few milliseconds at highest.
CHIME recorded a mysterious, repeating fast radio burst signal
During the before-mentioned period, they can send as much power as hundreds of millions of Suns. Also, most of them had only been detected once. Such a thing makes it hard to track those bursts to a source galaxy. Some FRBs, however, discharge repeating radio bursts, but extremely random. These are easiest to detect to a galaxy, but until now, that hasn’t sent us any closer insights.
Back in 2019, for example, the CHIME collaboration declared that they had identified a great eight new repeating FRBs, reaching the then sum of repeaters to 10 out of almost 155 FRB sources. FRB 180916.J0158+65 was one of the eight mentioned, and besides its repeat blasts, initially, it didn’t seem to be anything unique.
But as the CHIME analysis proceeded to watch the sky, a model resurfaced. “The discovery of a 16.35-day periodicity in a repeating FRB source is an important clue to the nature of this object,” explained the researchers. Black holes and stars are other cosmic features that proved periodicity manages to be binary systems.
