About 10 paragraphs down in the original article linked below.

Now that astronomers have seen an FRB that not only repeats but is also linked to something we can see, it’s possible to start exploring what it is, Chatterjee said.

According to study co-author Sara Burke-Spolaor, of the National Radio Astronomy Observatory in Socorro, New Mexico, one possibility is that they are blobs of gas getting hit by powerful jets. Galactic nuclei have supermassive black holes at their centers, and those black holes spew jets of subatomic particles such as electrons, positrons (the antimatter siblings of electrons) and some atomic nuclei at near the speed of light. (The origins of the jets are still somewhat mysterious). When a passing gas cloud hits one, it gets blasted and releases a burst of radio energy.

I am not sure whether the whole of the second paragraph is the opinion of Sara Burke-Spolaor or whether it is just the first sentence of that paragraph.

However, not being an astrophysicist, I thought black holes (the part I have emboldened) did not allow anything to escape due to their huge gravitational field. I understood that even light was not able to escape - hence the name "Black Hole".

It seems from this that small particles ARE able to escape.

From the standpoint of classical physics nothing should be able to escape from a black hole. But from the standpoint of quantum mechanics, the emission of what is called Hawking radiation, named after Stephen Hawking, from black holes is theorically possible.

You might find this paper by theoretical physicist Edward Witten interesting. In it he explains the quantum mechanics of black holes.

If I understand this pdf correctly, on a quantum mechanics level, a few atoms of water spilled on the floor could statistically possibly produce one or two of these finding their way back into the glass from which they were spilled. By the same token massive bodies attracted into a black hole could statistically produce a few particles which escape from the massive gravitational field of the black hole. This effect cannot be measured in black holes because there are too few particles escaping but appears to have parallels in other parts of physics.

Purely speculatory and coming from someone who is totally ignorant of much physics at all, but if black holes are actually as described in some sci-fi movies, then they expell their 'food matter' into other parts of the galaxy (or into other dimensions). This would preserve the balance of energy within the universe.

At the end of December 2016 we received 6 FRBs from the same area of space. This caused further speculation as to what might cause them since they are not often logged from the same area because they are so rare.

This article is probably reporting the same series of FRBs which are being reported in the original link above.

Scientists have discovered six more bursts of radio signals coming from a place in deep space outside our galaxy from where similar signals were detected earlier this year and in 2012.


A total of 17 such radio signals have been received from this location in space, and given their nature, speculation has already begun on whether we are being hailed by extra-terrestrial life forms.

Headquartered in Cambridge, Mass., the Harvard-Smithsonian Center for Astrophysics (CfA) is a joint collaboration between the Smithsonian Astrophysical Observatory and the Harvard College Observatory. CfA scientists, organized into six research divisions, study the origin, evolution and ultimate fate of the universe.
A recent article ( Thursday, March 9, 2017) by the Centre for Astrophysics at Havard
Could Fast Radio Bursts Be Powering Alien Probes?

Poses a question whether this could be caused by an intelligent species rather than a natural occurance.

When this type of organisation is thinking these types of thoughts and publishing them too, it must mean that ET is a valid possibility. Thats interesting.

Thanks to Mark S for this link in the paranormal forum.

A year ago, the research team pinpointed the location of FRB121102 and reported that it lies in a star-forming region of a dwarf galaxy at a distance of more than three billion light-years from Earth.

The enormous distance to the source implies that it releases a monstrous amount of energy in each burst - roughly as much energy in a single burst of one millisecond as the Sun releases in an entire day.
A new theory about the FRBs which may or may not be the answer. Article from BBC website 11 Jan 2018

Quote:
When polarised radio waves pass through a region with a magnetic field, the polarisation gets "twisted" by an effect known as Faraday rotation. And the stronger the magnetic field, the greater the twisting.

"The only sources in the Milky Way that are twisted as much as FRB121102 are in the galactic centre, which is a dynamic region near a massive black hole. Maybe FRB121102 is in a similar environment in its host galaxy," said Daniele Michilli, a co-author from the University of Amsterdam.

"However, the twisting of the radio bursts could also be explained if the source is located in a powerful nebula or supernova remnant," he added.

Being that we had all the recent news of the Pentagons secret involvement into UFOs and aliens over the years, as well as them even admitting they have recovered unknown metal alloys from various UAPs, that makes it clear we are already being visited and probably have been for a very long time. So why would it be news that some extraterrestrial civilization could be hailing us or sending signals out?

Unless they are speculating this may be from a less advanced civilization, one that is not yet able to come here, but may be able to send out signals to other worlds/ dimensions?

So, it seems there is no doubt these FRBs came from space... but there are always bugs in software.

Link 1 18Jun2018
Quote:
Professor Anne Green of the University of Sydney added, “it is very exciting to see the University of Sydney’s Molonglo telescope making such important scientific discoveries by partnering with Swinburne’s expertise in supercomputing.”

Green is referring to the new software which allowed the scientists to sift through all the data collected from Molonglo and pinpoint these three FRBs. The Ph.D. student at Australian National University, Manish Caleb, who designed the software said, “because of the telescope’s characteristics, we’re 100 percent sure the bursts came from space. We have scientifically confirmed that FRBs are extraterrestrial…we expect Molonglo will do this for more bursts.”
...

Quote:
Despite confirming their origin, scientists still do not know what they mean. One hypothesis is that these bursts could be remnants of alien space probes or even alien megastructures. In order to leave a trail that bright or long-lasting, it is surmised that the transmitter would need to have a surface area twice the size of Earth. This would require not only more advanced technology, but massive construction effort. Still, the stutter “heard” from the star KIC 8462852 would need an almost inconceivably-sized alien megastructure. The only reason a civilization would need to build a structure that size, scientists said, is for interstellar travel.

The raw power required to leave such a focused radio stream would be enough to propel a one million ton ship over vast distances.

“That’s big enough to carry living passengers across interstellar or even intergalactic distances,” cited Manasvi Lingam of Harvard University.

Such a ship would need radio beams to “push” its sails. These beams then leave traces in space which are detected by human technology as bright pockets in the sky. To that end, Harvard-Smithsonian Center for Astrophysics researcher Avi Loeb stated, “science isn’t a matter of belief, it’s a matter of evidence. Deciding what’s likely ahead of time limits the possibilities. It’s worth putting ideas out there and letting the data be the judge.”

These FRBs continue to happen and still no theories as to what causes them.


Link 1 (Article 05 Aug 2018)

Quote:
FRB 180725A (named for the year, month, and day it was detected) sent a low frequency wave of 580 megahertz, which is almost 200 MHz lower than other FRBs, according to a statement released in The Astronomer's Telegram .
"[O]ne such burst of mysterious energy whizzed past a new array of radio telescopes nestled in the mountains of British Columbia, Canada, registering one of the rarest radio frequencies ever detected," Live Science reported.


"These events have occurred during both the day and night, and their arrival times are not correlated with known on-site activities or other known sources," Patrick Boyle, project manager for the Canadian Hydrogen Intensity Mapping Experiment (CHIME) that detected it, per the report.
