Space Weather May Broaden Technosignatures, Challenging Narrowband SETI Searches

To the point

NASA-funded SETI Institute researchers say space weather can widen the frequency spread of technosignatures, which makes narrowband searches miss them; simulations show significant broadening for many stars and even larger effects during solar eruptions, so using higher radio frequencies and designing searches that account for how stellar activity reshapes signals is recommended, led by Vishal Gajjar and Grayce C. Brown.
