Mysterious fast repeating radio bursts (FRBs) from 'dead' galaxies have left astronomers puzzled and hoping to discover more, according to a recent study.
The Fed is known for its rapid flashing of radio waves, ABC News reported The researchers noted that these FRBs are coming from an unexpected source.
The paper said that the sources of FRBs were “previously associated with young magnetized neutron stars that consume large amounts of energy as they form.” But the dormant galaxies where these radio bursts occur should not contain these types of young stars, according to a paper published Wednesday in The Astrophysical Journal Letters. ”
According to the paper introductionFRBs are “bursts of radio emission with a duration of microseconds to milliseconds originating from extragalactic distances,” and although researchers have detected thousands of them, their origin remains a mystery. wrapped.
FRBs are expected to come from inside galaxies, but they're clearly on the outside of galaxies, where older or dead stars reside, Vishwangi Shah, a doctoral student in the physics department at McGill University in Montreal, told ABC News. Explained.
“This discovery was truly surprising and exciting,” she said.
Seth Szostak, Senior Astronomer at the SETI Institute, 2019 called The Fed makes a “radio burp” from space:
FRBs usually come from galaxies far away from our galaxy. Therefore, it is difficult for researchers to trace the source, Earth.com. reported Wednesday.
In 2024, researchers studied According to the Jet Propulsion Laboratory at the California Institute of Technology, the unusual behavior when a dead star emits an FRB is:
Two NASA X-ray telescopes recently observed such an event, known as a fast radio burst, just minutes before and just after it occurred. This unprecedented view puts scientists on the path to a deeper understanding of these extreme radio phenomena.
Although they last only a fraction of a second, fast radio bursts can release nearly as much energy as the sun releases in a year. Their light also forms laser-like beams, setting them apart from the more chaotic cosmic explosions.
Shah's team used the Gemini North telescope in Hawaii to pinpoint the origin of the burst, leading them to believe there was a faint galaxy there, but they had no idea it existed at first.
Shah said further study of the FRB will give researchers more insight into its origins and activity in the space between the Milky Way and more distant regions.
