Fast radio bursts (FRBs) are often mysterious in their origin, but it is not an uncommon phenomenon. A new study on an FRB discovered in November of 2018, reveals more about this, as well as in the vast galactic halo he went on and on.

The study, published in Science, notes that, in the signal FRB 181112 is also identified.

“The source of the fast radio burst, they expose the nature of the magnetic field of the galaxy, and the structure of the halo gas. The study demonstrates a new and innovative technique for the exploration of the nature of galaxy haloes,” said the study’s lead author, J. Xavier Prochaska, professor of astronomy and astrophysics at the University of California at Santa Cruz, in a statement.

FRB 181112, was located by the Australian Square Kilometre Array Pathfinder radio telescope. Follow-up observations using the ESO’s Very Large Telescope, found that the radio pulses are passed through the halo of a massive galaxy on the way to the Ground.

Prochaska and other researchers have used data from the Australian Square Kilometre Array Pathfinder radio-telescope and the European Southern Observatory’s (ESO) Very Large Telescope to make their observations.

“When we overlaid the radio and optical images, we were able to see that the fast radio burst, pierce to the halo of this agreement, showing the foreground galaxy, and, for the first time, we had a direct way of investigating the invisible matter around galaxies”, and one of the study’s co-authors, Cherie Day, it will be added to the list.

According to the EARTH, and the galactic halo, which has both dark and ordinary matter, which is largely comprised of hot, ionized gas.

The light-emitting portion of a huge galaxy, it would be about 30 000 light-years across, roughly spherical halo is about ten times larger in diameter, the” RING-written in the statement. Halo gas and star formation, as it is in the direction of the center of the milky way galaxy, while other processes, such as supernova explosions, that can eject material out of the star-forming region in the galactic ” halo.”

To the LEFT is added to that of the astronomers like to study halo gas to the understanding of the ejection process is completed, stars are being formed.

“These are the galaxy’s halo is a great food,” Prochaska adds. “The message was to a large extent remain unaffected by the galaxy, which is in stark contrast to the previous models of prediction, it would have been done in the history.”

More research is needed to determine whether it is the soothing nature of the halo is common, or if it is an exception to the rule. “This galaxy may be special,” Prochaska to continue. “We have to be fast to be a radio outbursts and to study dozens or hundreds of star systems, over a range of masses and ages, the rate of the population as a whole.”


It is not known how often the FRBs and most of their origins are mysterious.

Some researchers have speculated that they originate from an alien civilization, as well as others, including the Search for Extraterrestrial Intelligence Institute, or SETI, has said that the statement, “don’t.” They come from every corner of the space and the arrangement of the co-operative alien’s behavior, when the one-way communication cost of billions and billions of years is unlikely to be careful,” SETI wrote in a September blog post.

For the first time, discovered in 2007, the FRBs are relatively new to astronomers, and their origins are mysterious. According to ScienceAlert, some of them will be able to generate as much energy as a 500-million suns, within a few milliseconds.

In July, 2018 and, as a FRB that the Earth was hit, it was close to 200 mhz and lower than that of the other radio burst has ever been found.
