Surprising New Features of Mysterious Fast Radio Bursts Defy Current Understanding

Fast Radio Bursts – A Puzzling and Deepening Mystery
An international team of scientists reveals an evolving, magnetized environment and surprising source location for deep-space fast radio bursts – observations that defy current understanding.
Fast radio bursts (FRBs) are millisecond-long cosmic explosions that each produce the energy equivalent to the sun’s annual output. Their perplexing nature continues to surprise scientists more than 15 years after the deep-space pulses of electromagnetic radio waves were first discovered. Now, newly published research only deepens the mystery surrounding them.
Unexpected new observations from a series of cosmic radio bursts by an international team of scientists challenge the prevailing understanding of the physical nature and central engine of FRBs. The researchers, which includes University of Nevada, Las Vegas (UNLV) astrophysicist Bing Zhang, published their findings in the September 21 issue of the journal Nature.
The Five-hundred-meter Aperture Spherical radio Telescope (FAST) is located in a natural depression in the landscape in Guizhou, China. It is the world’s largest single-dish radio telescope, with a 500 meter (1,600 foot) diameter dish and a receiving area equivalent to 30 football fields. It is anticipated that FAST will maintain its world-class status for the next 20 to 30 years. With its innovative design, FAST has broken the 100-meter engineering limit for telescope construction and created a new mode to build large radio telescopes.
The cosmic FRB observations were made in late spring 2021 using the massive Five-hundred-meter Aperture Spherical radio Telescope (FAST) in China. The team detected 1,863 bursts in 82 hours over 54 days from an active fast radio burst source called FRB 20201124A. The scientists were led by Heng Xu, Kejia Lee, Subo Dong from Peking University, and Weiwei Zhu from the National Astronomical Observatories of China, along with Zhang.
“This is the largest sample of FRB data with polarization information from one single source,” said Lee.
Recent observations of a fast radio burst from our 
The Five-hundred-meter Aperture Spherical radio Telescope (FAST), nicknamed Tianyan (“Eye of the Sky/Heaven”) is a radio telescope located in the Dawodang depression, a natural basin in Pingtang County, Guizhou, southwest China. It consists of a fixed 500-meter diameter dish constructed in a natural depression in the landscape. It is the world’s largest filled-aperture radio telescope, and the second-largest single-dish aperture after the sparsely-filled RATAN-600 in Russia.
What makes the latest observations surprising to scientists is the irregular, short-time variations of the so-called “Faraday rotation measure,” essentially the strength of the magnetic field and density of particles in the vicinity of the FRB source. The variations went up and down during the first 36 days of observation and suddenly stopped during the last 18 days before the source quenched.
“I equate it to filming a movie of the surroundings of an FRB source, and our film revealed a complex, dynamically evolving, magnetized environment that was never imagined before,” said Zhang. “Such an environment is not straightforwardly expected for an isolated magnetar. Something else might be in the vicinity of the FRB engine, possibly a binary companion,” added Zhang.
To observe the host galaxy of the FRB, the team of astronomers also made use of the 10-m Keck telescopes located at Mauna Kea in Hawaii. Zhang says that young magnetars are believed to reside in active star-forming regions of a star-forming galaxy, but the optical image of the host galaxy shows that – unexpectedly – it’s a metal-rich barred spiral galaxy like our Milky Way. The FRB location is in a region where there is no significant star-forming activity.
“This location is inconsistent with a young magnetar central engine formed during an extreme explosion such as a long gamma-ray burst or a superluminous supernova, widely speculated progenitors of active FRB engines,” said Dong.

Astronomers Shocked By Mysterious Radio Waves That Seem to Defy Physics
This is really out there.
Wave Goodbye
New observations of a far-flung galaxy cluster have left a group of scientists stumped as they ponder whether they’ve discovered a new form of physics.
In their new paper, researchers Tessa Vernstrom of The University of Western Australia and Christopher Reisely from Italy’s Università di Bologna describe how their discovery of a series of large, low frequency radio wave-emitting objects in a galaxy cluster about 800 million light-years away appear to defy the laws of physics.
Using radio and X-Ray telescopes, the researchers discovered three large, radio wave-emitting objects — a fossil radio emission, a radio relic, and a radio halo — within the Abell 3266 galaxy cluster.
These kinds of objects are relatively rare, the researchers noted, but not entirely unheard of.
Zoom In
These three objects were all too faint to detect until the researchers applied a complicated algorithm to the telescope imagery of the galaxy cluster — and in doing so, found the ancient remnants of a supermassive black hole that created the galaxy cluster.
Abell 3266’s radio relic in particular caught the researchers’ attention, a sonic boom-like arc of radio waves that are “powered by shockwaves [traveling] through the plasma,” as the they noted in a piece for The Conversation.
This relic is unlike any radio object scientists have ever seen before, according to the team, due to its highly unusual concave shape, earning it its “wrong-way relic” nickname.
“If it’s a shock wave, you might think it would bend down like an arc around the edge,” Vernstrom told ABC Australia, “but this one is flipped around.”
Wrong Turn
The researchers are now faced with a puzzle.
“Our best physical models simply can’t fit the data,” the researchers wrote in The Conversation. “This reveals gaps in our understanding of how these sources evolve – gaps that we’re working to fill.”
That means the team has to go back to the drawing board.
“Maybe there’s some kind of new physics going on there that we haven’t fully understood,” Vernstrom concluded, “when our models can’t match the observations.”
