Summary of the First Year of the Space Weather Around Young Suns Program: 900 Hours of Low-frequency Radio and Optical Data Dedicated to Young, Solar-type Stars
Ivey Davis, Gregg Hallinan, Nikita Kosogorov +51
The Space Weather Around Young Suns (SWAYS) program was introduced in \citet{Davis2025} as a multi-wavelength monitoring program for studying the activity and particle environments…
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…
COMAP Pathfinder -- Season 2 results I. Improved data selection and processing
J. G. S. Lunde, N. -O. Stutzer, P. C. Breysse +24
The CO Mapping Array Project (COMAP) Pathfinder is performing line intensity mapping of CO emission to trace the distribution of unresolved galaxies at redshift . We pres…
COMAP Pathfinder -- Season 2 results II. Updated constraints on the CO(1-0) power spectrum
N. -O. Stutzer, J. G. S. Lunde, P. C. Breysse +24
We present updated constraints on the cosmological 3D power spectrum of carbon monoxide CO(1-0) emission in the redshift range -. The constraints are derived from the two…
