Vishal Gajjar is an astronomer at the seti-institute and lead author of the 2026 Astrophysical Journal paper on stellar-plasma-scattering of radio technosignatures (see src-plasma-technosignature-scattering-2026). His work demonstrates that stellar wind plasma turbulence and coronal mass ejections near a transmitting planet can broaden narrowband radio signals before they exit the home system, causing them to evade standard seti detection pipelines. He argues this effect may partly explain the radio silence seen in technosignatures surveys.
