Article Synopsis
- Fast Radio Bursts (FRBs) are powerful, brief astrophysical events that have been detected at various frequencies, but lower-frequency emissions have been challenging to observe.
- One notable FRB, FRB 20180916B, shows a 16.35-day periodicity and emits at frequencies as low as 120 megahertz, with its activity window varying by frequency — narrower and earlier at higher frequencies.
- The findings indicate that lower-frequency emissions can escape their surrounding medium, suggesting that some FRBs are in environments that don't absorb low-frequency signals, contradicting previous theories about absorption affecting FRB periodicity.
