More Fast Radio Bursts Have Been Detected From Auriga

If you have interests in capturing a weird fast radio burst, namely FRB, it seems that the best option you should choose is the constellation of Auriga (the charioteer), because 17 FRBs have been detected there from the same source.

As they were all released by a single source, it is reasonable that astronomers are quite excited since it is the only repeating FRB, which was found at the earlier days this year. Such unique discovery, also called as FRB 121102, has made these phenomena much more mysterious.

As the unbelievably high-energy phenomenon, FRBs are a quick flash of radio waves which could last just for a few milliseconds. Since their discovery in 201, a lot of explanations have been given to illustrate what is inexplicable, such as outlandish and improbable alien communication systems.

According to the intensity of the signal, scientists were clear that the source must have had an extragalactic origin. From the speed at which they appear and disappear, it could indicate that a one-off event might take place, something like a collision between stars. But FRB 121102 has thrown a spanner in that line of thought.

In in the paper published in the Astrophysical Journal, the authors wrote that

their discovery of repeating bursts from FRB 121102 had shown that for at least one source, the origin of the bursts could not be cataclysmic, and it should be able to repeat on short [less than 1 minute] timescales. And the authors also believed that no matter FRB 121102 was a unique object in the currently known sample of FRBs, or all FRBs were able to repeat, its characterization was very vital to understanding fast extragalactic radio transients.

The international group of scientist has doubt that the source is a young neutron star embedded in a dense cloud from either a star-forming region (like the Pillars of Creation) or a supernova remnant.

However we know quite little about the source, because we are not able to establish a distance owing to the fact that we are still trying to find the galaxy that is hosting the source using visible light. Since less than 20 different sources of FRBs exist, no one is actually certain what we are seeing.

What is yet to be known is half the fun in the field of astronomy. Researchers expect there are 10,000 FRBs released from every direction in the sky each day. What we should do is to take the telescope pointed to the right place at the right time. If we could find more like FRB121102, it could finally help us solve this cosmic puzzle.
