Three Fast Radio Bursts Punched Right Through a Nearby Galaxy By Nancy_A
Scientists say the new data and images are much sharper than previously possible. That allowed the multiple bursts that punched through the nearby Triangulum Galaxy to immediately pinpointed.said principal investigator Joeri van Leeuwen from ASTRON.FRBs are among the brightest explosions in the universe. The bursts contain immense amounts of energy, approximately ten trillion times the annual energy consumption of the entire world population, according to ASTRON.
By investigating the flashes, astronomers hope to better understand the fundamental properties of the matter that makes up the universe. But studying these flashes is difficult. No one knows where in the sky the next burst will go off, and they only last a millisecond.Previously, radio telescopes could only roughly indicate where an FRB occurred. But the ARTS upgrades now enables Westerbork to determine the exact location of an FRB very accurately.
“We demonstrated that three of the FRBs we discovered had skewered our neighbour, the Triangulum Galaxy!” said Van Leeuwen. “We were thus able to count how many invisible electrons that galaxy contains at most, for the first time. A fantastic result.”In theirthey found they could expect to detect a new FRB approximately once every seven days, which they said ensures a considerable number of new sources to study.
“The combination of detection rate and localization accuracy …thus marks a new phase in which a growing number of bursts can be used to probe our Universe,” t By continuing to pinpoint the sources and study FRBs, astronomers hope to not only learn more about the radio bursts, but also about the mysterious dark matter and dark energy that makes up about 95% of the Universe.
