They are called rapid radio blasts or FBBs and these off-shore signals remain hidden. But thanks to the largest radio telescope in Canada, astrophysics finds a lot in search to find out why these things are amazing.
The first FRB in 2007 was a astrophysicist and pupil in New South Wales, Australia, from the Parks Observatory in 2001. discovered during research. Tens of others have been identified since then. Scientists have not yet been able to find out about these signals.
But the short cuts that crossed the universe – and only milliseconds – was another surprise: some of them were repeated.
The first of these replicators was opened by McGill PhD Dr. Paul Scholz in 2015. The second version was found last January. This list is being expanded.
In a new study, A group of Canadian scientists, previously sent to the Astrophysical Journal Letters and posted on arXiv.org, has identified eight more recurrent FBs on the Canadian hydrogen intensification experiment (CHIME) telescope.
The results of the research are an important step towards better understanding of what these strong signals are and where they come from.
"The first big conclusion [from the paper] this is not anomalous phenomenon. That's real, "said Victoria Caspi, an astrophysicist at the University of Cardiff and the Canadian Institute for Advanced Studies (CIFAR)." It takes time and patience to find them. Secondly, this gives them the opportunity to isolate them and this is very great in the FRB field. "
The CHIME instrument is sensitive or inaccessible in its definition, so it can not localize the signal. Instead, his task is to find as many people as possible. Their actual location is in line with other telescopes.
STORAGE: The telescope CHIME is put into operation
"It's very important to find eight eyes, because we have a recurrent FB and if we track them with other telescopes, then we can identify the environment and galaxies of this FDR," says Prague Chavla. and McGill PhD doctorate at the Space Institute.
Only 10 of the 10 recaptured FRBs have reached their destination: one in the dwarf galaxy, the other in the spiral galaxy.
More FRB can be detected
FBB is an urgent topic in the astronomical world as it is a new discovery and the mechanism of response is unclear.
"We think we understand what is in space," Kaspi said. "But there was a sudden explosion in the radio. Nobody expected them. No one has predicted them. Indeed, this was a technological breakthrough, and we were able to see it. In my opinion, it's very interesting to know what's really going on right now. in the universe. "
Because they produce such intense energy, some theories suggest that this is a neutron star, a dense star that remains after a very new star. Another theory suggests that it can be a magnet with a very strong magnetic field similar to that of a neutron star.
Known FBBs – both replicators and non-replicates are thought to emerge in other galaxies, but one that is newly discovered is closer to one another, perhaps even to our galaxies. However, if Chávla is found in our galaxy, "that would be surprising.
"We know many neutron stars that emit such pulses in our galaxy, but none of them have ever been found on the edge of our galaxy."
CHIME was very successful in looking for these amazing things, but even better news is that the telescope does not work at full capacity: it should be checked carefully. It is expected that more FRB will be detected daily after the completion. This means more data for other astrophysicists to provide their own secrets.
"I think the coming year will be a good year for FRB," Kaspi said. "Will we know the answer in a year? I do not know. I do not know. Maybe. But in a year we will achieve significant results. "
