Exo–IPM Scattering as a Hidden Gatekeeper of Narrowband Technosignatures

The Astrophysical Journal
Narrowband radio technosignatures can be significantly modulated by the host star’s exoplanetary interplanetary medium (Exo-IPM), where turbulence in stellar winds and coronal mass ejections (CMEs) imprint spectral broadening.

All-sky Ultra-narrowband Spectral Imaging with the OVRO–LWA: Technosignature Constraints and Axion-like Particle Prospects

The Astronomical Journal
We present an imaging-domain search for technosignatures at decametric wavelengths with the Owens Valley Radio Observatory Long Wavelength Array, targeting ultra-narrowband continuous-wave signals between 50 and 86 MHz.
