The MegaWave Radio Surveyor
T. Joseph W. Lazio, Evgenya Shkolnik, James Aguirre +40
Several Decadal-level questions in astrophysics, exoplanets, astrobiology, and cosmology can be addressed only at low radio frequencies inaccessible from Earth. The MegaWave Radio…
All-Sky Ultra-Narrowband Spectral Imaging with the OVRO-LWA: Technosignature Constraints and Axion-Like Particle Prospects
Nikita Kosogorov, Gregg Hallinan, Greg Hellbourg +46
We present an imaging-domain search for technosignatures at decametric wavelengths with the OVRO-LWA, targeting ultra-narrowband continuous-wave signals between 50 and 86 MHz. We i…
A Commensal Radio-Only Cosmic Ray Detector at the Owens Valley Radio Observatory Long Wavelength Array
Kathryn A. Plant, Andrew Romero-Wolf, Gregg Hallinan +46
The brief (10 nanoseconds) transient radio emission from cosmic ray air showers carries key information about the energy and mass composition of high energy cosmic rays, but anthro…
Upper Limits on Pulsed Radio Emission from Unseen Compact Objects in Six Galactic Stellar Binaries
Melanie Ficarra, Fronefield Crawford, T. Joseph W. Lazio
We have conducted a search for radio pulsars in six Galactic stellar binary systems having unseen primary stars. All six systems have estimated primary masses in the range that cou…
