Astronomers Trace Fast Radio Burst to a Distant, Deep-Space Galaxy


The burst's host galaxy is more than halfway across the observable universe and up to 100 times fainter than other host galaxies.



Astronomers have traced a fast radio burst (FRB) back to its origin, and what they've found is unlike any other FRB host previously discovered. The signal appears to have come from a tiny dwarf galaxy more than halfway across the observable universe, making it at least 46 billion light-years from Earth. This incredible distance and the galaxy's small but mighty stature bring researchers a little closer to understanding how fRBs come to fruition.

FRBs are brief but highly intense bursts of energy detected in radio-wave frequencies. Though short-lived, these electromagnetic eruptions are often powerful enough to outshine entire galaxies. This alone is strange enough to warrant investigation, but FRBs might also have something to teach astronomers about the evolution of the universe and the properties of the intergalactic medium, by which they're sometimes distorted as they travel. They also lead astronomers to "new" host galaxies, as FRB 20190208A has done.

An international team of astronomers first detected FRB 20190208A in February 2019. Using radio telescopes, the team observed the burst for just under 66 hours, then caught it again in February 2021 and August 2023. This meant FRB 20190208A was a repeating FRB, the likes of which were only discovered half a decade ago.

FRB 20190208A's persistent pops allowed the astronomers to track down its origin, and then use optical telescopes to scope out the area. At first, they struggled to find a galaxy from which the burst might have originated. Then, on closer examination, they found a "faint smudge" in deep space. The smudge was a small and faint dwarf galaxy, and while the team hasn't yet nailed down its exact distance from Earth, they estimate that it sits at least halfway across the observable universe. That would make the host galaxy 46 billion light-years from Earth at minimum, though that doesn't mean FRB 20190208A traveled for so long; accounting for the expansion of the universe, the astronomers think the burst traveled for some 7 billion years.

Though the exact cause of FRBs has been difficult to nab, scientists think they're formed by a type of neutron star called a magnetar, whose powerful magnetic field snaps in a sudden burst of energy. Strangely, repeating FRBs like FRB 20190208A seem to be more strongly associated with dwarf galaxies than with larger galaxies, suggesting that the former provide an optimal environment for magnetars and potentially other FRB sources that astronomers haven't yet tracked down.

"Finding repeating FRB sources in dwarf galaxies thus potentially links these repeating FRB sources with massive star progenitors," Danté Hewitt, a radio astronomer involved in the research, told ScienceAlert. "It's a little poetic. When the most massive stars die, they unleash some of the most energetic explosions in the universe; and then maybe, the remnants of those explosions continue to scream into the void, repeatedly producing FRBs."

Freezing light? Italian scientists froze fastest thing in universe, here’s how

In a rare occurrence, physics made it possible to control the fastest travelling element - light. Italian scientists have managed to freeze the light, as per reports. A recent study published in a British weekly journal reportedly revealed that light can exhibit ‘ supersolid behavior ’ a unique state of matter that flows without friction while retaining a solid-like structure. The research, led by Antonio Gianfate from CNR Nanotec and Davide Nigro from the University of Pavia, marks a significant step in understanding supersolidity in light. The scientists described their findings as “just the beginning” of this exploration, as per reports. In what can be termed as ‘manipulating photons under controlled quantum conditions ’, the scientists demonstrated that light, too, can exhibit this behaviour. (A photon is a bundle of electromagnetic energy which is massless, and travel at the speed of light) How did scientists freeze light? As we know, freezing involves lowering a liquid’s tempera...

Physicists observe a new form of magnetism for the first time

MIT physicists have demonstrated a new form of magnetism that could one day be harnessed to build faster, denser, and less power-hungry " spintronic " memory chips. The new magnetic state is a mash-up of two main forms of magnetism: the ferromagnetism of everyday fridge magnets and compass needles, and antiferromagnetism, in which materials have magnetic properties at the microscale yet are not macroscopically magnetized. Now, the MIT team has demonstrated a new form of magnetism , termed "p-wave magnetism." Physicists have long observed that electrons of atoms in regular ferromagnets share the same orientation of "spin," like so many tiny compasses pointing in the same direction. This spin alignment generates a magnetic field, which gives a ferromagnet its inherent magnetism. Electrons belonging to magnetic atoms in an antiferromagnet also have spin, although these spins alternate, with electrons orbiting neighboring atoms aligning their spins antiparalle...
