One of the rare and brief bursts of cosmic radio waves that have puzzled astronomers since they were first detected nearly 10 years ago has finally been tied to a source: an older dwarf galaxy more than 3 billion light years from Earth.

The continuing barrage from this repeating source, roughly 3 billion light - years away in the constellation Auriga, implies that whatever is causing some radio bursts is not a one - time destructive

«Fast radio bursts are exceedingly bright given their short duration and origin at great distances, and we haven't identified a possible natural source with any confidence,» said theorist Avi Loeb of the Harvard - Smithsonian Center for Astrophysics.

Dark matter hitting black holes could be the source of some fast radio bursts — mysterious blasts of radio waves that come from billions of light years away, first detected 10 years ago.

New detections of radio waves from a repeating fast radio burst have revealed an astonishingly potent magnetic field in the source's environment, indicating that it is situated near a massive black hole or within a nebula of unprecedented power.

«A repeating fast radio burst from an extreme environment: Extragalactic source of radio - wave flashes resides in a powerfully magnetized astrophysical region.»

The amount of twisting observed in FRB 121102's radio bursts is among the largest ever measured in a radio source, leading the researchers to conclude that the bursts are passing through an extraordinarily strong magnetic field in a dense plasma.

The observations by the Breakthrough Listen team at UC Berkeley using the Robert C. Byrd Green Bank Telescope in West Virginia show that the fast radio bursts from this object, called FRB 121102, are nearly 100 percent linearly polarized, an indication that the source of the bursts is embedded in strong magnetic fields like those around a massive black hole.

Fast radio bursts are brief, bright pulses of radio emission from distant but so far unknown sources, and FRB 121102 is the only one known to repeat: more than 200 high - energy bursts have been observed coming from this source, which is located in a dwarf galaxy about 3 billion light years from Earth.

That points to neutron stars — which form when short - lived massive stars in stellar nurseries die — as the source of fast radio bursts.

Scientists have identified the source of mysterious flashes of cosmic radio waves known as fast radio bursts: a surprisingly small galaxy more than 3 billion light - years away.

Those observations reveal that the location of the bursts coincides with a faint, remote galaxy that also hosts a persistent source of radio waves.

«This impressive result shows the power of several telescopes working in concert — first detecting the radio burst and then precisely locating and beginning to characterize the emitting source,» said Phil Puxley, a program director at the National Science Foundation that funds the VLA, VLBA, Gemini and Arecibo observatories.

These fast radio bursts (FRBs) are brief, bright pulses of radio emission from distant but unknown sources.

In addition to detecting the bright bursts from FRB 121102, the VLA observations also revealed an ongoing, persistent source of weaker radio emission in the same region.

Astronomers at Sweet Briar College and the Naval Research Laboratory have detected a powerful new bursting radio source whose unique properties suggest the discovery of a new class of astronomical objects.

«These ultra high precision observations showed that the bursts and the persistent source must be within 100 light - years of each other,» said Jason Hessels, of the Netherlands Institute for Radio Astronomy and the University of Amsterdam.

They are also developing (with Dr. Kent Wood of NRL) a model that attempts to account for the radio bursts as a new type of outburst from a class of sources known as «magnetars.»

Observing a fast radio burst in conjunction with neutrinos would be a coup, helping establish source objects for both types of phenomena.

«Fast radio bursts are exceedingly bright given their short duration and origin at great distances, and we haven't identified a possible natural source with any confidence,» said Harvard professor Avi Loeb.

Also, astronomers familiar with the signal are considering the possibility of a microlensing event — a distant radio source may have been momentarily amplified by HD164595 through the warping of spacetime, creating a cosmic lens, making the radio signal look like a suspect radio burst.

Either way, if the researchers fail to spot a dimming of the steady radio source associated with the Spitler burst, then the whole magnetar theory may be ready for the astrophysical scrapheap.

They hope to localize more bursts to see whether they usually live in dwarf irregular galaxies, and whether they all appear alongside steady radio sources, both of which would support the newborn - magnetar theory.
