Recently, astronomers have reported a fast radio burst (FRB) whose characteristics are different from almost all other FRBs previously detected, except one.
The scientists used the National Science Foundation’s Karl G Jansky Very Large Array (VLA) and other telescopes to study the object.
About Fast radio burst
- FRBs are bright flashes of light that appear for a few milliseconds and then vanish. Since the first FRB was discovered in 2007, 140 more were discovered until June 2021.
- Their origins are unknown, and their appearance is unpredictable.
- FRB 20190520B, first discovered in 2019.
- What makes it different is that unlike many other FRBs, it emits frequent, repeating bursts of radio waves.
- And between bursts, it constantly emits weaker radio waves.
- The detection and localization of the repeating FRB 190520B, which is co-located with a compact, persistent radio source and associated with a dwarf host galaxy of high specific-star-formation.
- Only one FRB has been previously observed to behave this way. Called FRB 121102, that was discovered in 2012.
