Story summary

Since 2023, Japanese researchers at Hirosaki University, led by Hideki Asada and Shun Yamamoto, study nanohertz gravitational waves detected from pulsars.
They propose a method to identify wave sources by analyzing beats when similar frequencies interact.
The work, published in the Journal of Cosmology and Astroparticle Physics, could distinguish cosmic inflation from supermassive black hole binaries as sources, pending 5-sigma confirmation.
