News – Canadian astronomers have burst mysterious radio 2

Thursday, January 10, 2019, 4:23 a.m. – In the deepest space, there are radio signals that astronomers do not understand. Now a Canadian research team has found a recurring sign, only the second of its kind is found.

Fast radio stations or FRBs are cosmic radio stations that last only in milliseconds. The source is a powerful magnetic field that generates a signal through the radio frequency band.

In a new paper published in the Nature magazine, researchers reveal in the British telescope of British Columbia that the Canadian Hydrogen Intensity Mapping Experiment (CHIME) has 13 more FRBs, but, more importantly, it repeated FRB the second time.

The first FRB 121102 was discovered in 2007 in the telescope data in 2001. Since then, 36 have been found – only 19 summer researchers using an Australian radio telescope.

But it is not known that powerful radio signals from distant galaxies. There are many theories, even if foreigners are involved, but some of the major theories have magnetic iman magnetor like magnetic magnetization.

In 2015, Dr. Fred Scholz, a Ph.D. graduate of McGill University, previously detected FRB, repeated it. Astronomers have already scratched themselves on a cosmic puzzle.

MYSTERY

"We are surely sure that CHIME telescopes can find fast radio stations," said Ingrid Ladders, a member of the CHIME group and the astrophysics of the British Columbia University. "And we were lucky enough to tackle 13 of these things in the phase".

In the phase of prediction the telescope was not extended to its full potential. In fact, it was only a quarter of a quarter to be able to watch.

Kendrick Smith, Waterloo, Ont. -Cosmologist from the Perimeter Theoretical Physics Institute worked on a detective software, FRB is a unique challenge.

"FRB was an unexpected mystery. There are not so many qualitative mechanisms in astrophysics," Smithe said. "So, in its recent years, its character has become one of the greatest astrophysic problems."

FRBs are similar to pulleys, small and fast rotating, similar to solid star emitting signals, similar to cosmic ocean. However, our pulse has been found in our galaxy. The FRB to be detected from other galaxies means that the signal must be brighter than a pulse.

"That's the way to continue with 12. That's great," said Shriharsh Tendulka, an astronomer at McGill University and a member of CHIME. "We do not know how to make something shiny".

The discovery of FRBs may be a strange discovery, but they are more foreign than their counterparts. In normal FRBs, they emit a single spike. But in both repeaters, astronomers have found nails that come in different frequency and some time.

"We do not have such a structure as the fastest radiocommunications in this single explosion," said Tendulker. "So it's exciting. It highlights the difference between its internal mechanisms."

These 13 FRBs, including the repeater, were detected before being detected. Most FRBs are in frequencies of around 1400 MHz (MHz). But 400 to 800 MHz were discovered.

"CHIME's bandwidth sits in that gap where we did not know anything, so it's fantastic," Tendillo said. "It gives us more information".

BEFORE YOU NEED

The stairs leads to discovery of a "stunning group" of PhD PhD researchers, and there are more discoveries on the horizon.

"CHIME is looking at the whole northern sky every day, so you'll find plenty of opportunities to find some of these things," he said. "In a different way we found such a thing, there could be much more."

With regard to the mystery behind the FRB, and especially those that are repeated, the Canadian team expects CHIME to be in full capacity, with more repeaters revealing themselves.

"CHIME is still in the beginning and the most exciting results are still coming," Smithe said.
