Stellar Space Weather Could Blur Narrowband Signals and Explain SETI Silence

To the point

Space weather from stellar winds and eruptions around distant stars can blur and broaden narrow radio signals, which can hide them from SETI detectors, and by calibrating this broadening with solar data and making searches more flexible in frequency and timing, we could improve the chances of detecting technosignatures even if signals are intermittently masked.

If a signal gets broadened by its own stars environment, it can slip below our detection thresholds, even if its there.
