What to know about Scientific Discovery and Research

Astronomers used the CHIME telescope to conduct follow-up observations of the highly active fast radio burst source, FRB 20220912A. The monitoring campaign detected 828 bursts over 201.2 hours, revealing that the source's mean weekly burst rate changes significantly over time. The study also determined the source's total energy output, suggesting it may reside in a unique local environment.

Why it matters

Results of the monitoring campaign, published April 10 on the preprint server arXiv, could help us better understand the nature of these enigmatic sources.

Common ground

Fast radio bursts (FRBs) are intense bursts of radio emission lasting milliseconds showcasing the characteristic dispersion sweep of radio pulsars.
