Exoplanetary Space Weather Broadens Narrowband Signals, Reshaping Technosignature Search Strategies

To the point

Vishal Gajjar's study shows that turbulent space weather around other stars can broaden ultra-narrowband radio signals at the source, spreading power across nearby frequencies and lowering peak intensity so traditional spike-like searches may miss them, especially near active M dwarfs, and Grayce C. Brown notes we should adjust search pipelines to detect signals spread across a band or varying in time rather than single-channel spikes, a point echoed by EXO WORLDS discussions advocating broader technosignature strategies.
